Integration Testing For Testers In Flutter

Hi everyone! today we start learning about Integration testing in a flutter, It is the phase in software testing in which individual software modules are combined and tested as a group. Integration testing is conducted to evaluate the compliance of a system or component with specified functional requirements. It occurs after unit testing and before system testing.

What is Integration Testing?:

INTEGRATION TESTING is defined as a type of testing where software modules are integrated logically and tested as a group. A typical software project consists of multiple software modules, coded by different programmers. The purpose of this level of testing is to expose defects in the interaction between these software modules when they are integrated

Integration Testing focuses on checking data communication amongst these modules. Hence it is also termed as ‘I & T’ (Integration and Testing), ‘String Testing’, and sometimes ‘Thread Testing’.

Why do Integration Testing?:

Although each software module is unit tested, defects still exist for various reasons like

  • A Module, in general, is designed by an individual software developer whose understanding and programming logic may differ from other programmers. Integration Testing becomes necessary to verify the software modules work in unity
  • At the time of module development, there are wide chances of change in requirements by the clients. These new requirements may not be unit tested and hence system integration Testing becomes necessary.
  • Interfaces of the software modules with the database could be erroneous
  • External Hardware interfaces, if any, could be erroneous
  • Inadequate exception handling could cause issues.

Example of Integration Testing:

Let us assume that we have a Gmail application where we perform the integration testing.

First, we will do functional testing on the login page, which includes the various components such as username, password, submit, and cancel buttons. Then only we can perform integration testing.

The different integration scenarios are as follows:

> Scenarios1:

  • First, we log in as P users and click on the Compose mail, and perform the functional testing for the specific components.
  • Now we click on the Send and also check for Save Drafts.
  • After that, we send a mail to Q and verify in the Sent Items folder of P to check if the send mail is there.
  • Now, we will log out as P and login as Q and move to the Inbox, and verify if the mail has reached.

> Secanrios2: We also perform the integration testing on Spam folders. If the particular contact has been marked as spam, then any mail sent by that user should go to the spam folder and not in the inbox.

Note: We will perform functional testing for all features, such as to send items, inbox, and so on.

As we can see in the below image, we will perform functional testing for all the text fields and every feature. Then we will perform integration testing for the related functions. We first test the add user, list of users, delete user, edit user, and then search user.

Note:

  • There are some features, we might be performing only the functional testing, and there are some features where we are performing both functional and integration testing based on the feature’s requirements.
  • Prioritizing is essential, and we should perform it at all the phases, which means we will open the application and select which feature needs to be tested first. Then go to that feature and choose which component must be tested first. Go to those components and determine what values to be entered first.
    And don’t apply the same rule everywhere because testing logic varies from feature to feature.
  • While performing testing, we should test one feature entirely and then only proceed to another function.
  • Among the two features, we must be performing only positive integrating testing or both positive and negative integration testing, and this also depends on the features needed.

Types of Integration Testing:

Integration testing can be classified into two parts:

  • Incremental integration testing
  • Non-incremental integration testing

> Incremental Testing:

In the Incremental Testing approach, testing is done by integrating two or more modules that are logically related to each other and then testing for the proper functioning of the application. Then the other related modules are integrated incrementally and the process continues until all the logically related modules are integrated and tested successfully.

1) Bottom-up Integration Testing: It is a strategy in which the lower-level modules are tested first. These tested modules are then further used to facilitate the testing of higher-level modules. The process continues until all modules at the top level are tested. Once the lower-level modules are tested and integrated, then the next level of modules is formed.

Diagrammatic Representation:

Advantages:

  • Fault localization is easier.
  • No time is wasted waiting for all modules to be developed unlike the Big-bang approach

Disadvantages:

  • Critical modules (at the top level of software architecture) which control the flow of applications are tested last and may be prone to defects.
  • An early prototype is not possible

2) Top-down Integration Testing: It is a method in which integration testing takes place from top to bottom following the control flow of the software system. The higher-level modules are tested first and then lower-level modules are tested and integrated to check the software functionality. Stubs are used for testing if some modules are not ready.

Diagrammatic Representation:

Advantages:

  • Fault Localization is easier.
  • Possibility to obtain an early prototype.
  • Critical Modules are tested on priority; major design flaws could be found and fixed first.

Disadvantages:

  • Needs many Stubs.
  • Modules at a lower level are tested inadequately.

Sandwich Testing:

Sandwich Testing is a strategy in which top-level modules are tested with lower-level modules at the same time lower modules are integrated with top modules and tested as a system. It is a combination of Top-down and Bottom-up approaches therefore it is called Hybrid Integration Testing. It makes use of both stubs as well as drivers.

How to do Integration Testing?:

The Integration test procedure irrespective of the Software testing strategies (discussed above):

  1. Prepare the Integration Tests Plan
  2. Design the Test Scenarios, Cases, and Scripts.
  3. Executing the test Cases followed by reporting the defects.
  4. Tracking & re-testing the defects.
  5. Steps 3 and 4 are repeated until the completion of Integration is successful.

Brief Description of Integration Test Plans:

It includes the following attributes:

  • Methods/Approaches to testing (as discussed above).
  • Scopes and Out of Scopes Items of Integration Testing.
  • Roles and Responsibilities.
  • Pre-requisites for Integration testing.
  • Testing environment.
  • Risk and Mitigation Plans.

Entry and Exit Criteria of Integration Testing:

Entry and Exit Criteria to Integration testing phase in any software development model

Entry Criteria:

  • Unit Tested Components/Modules
  • All High prioritized bugs were fixed and closed
  • All Modules to be code completed and integrated successfully.
  • Integration tests Plan, test case, scenarios to be signed off and documented.
  • Required Test Environment to be set up for Integration testing

Exit Criteria:

  • Successful Testing of Integrated Application.
  • Executed Test Cases are documented
  • All High prioritized bugs were fixed and closed
  • Technical documents to be submitted followed by release Notes.

Conclusion

This is all about Integration testing and its implementation in both the White box and Black box techniques. Hope we explained it clearly with relevant examples.

Test Integration is an important part of the testing cycle as it makes it easier to find the defect when two or more modules are integrated to integrate all the modules all together in the first step itself.

It helps in finding the defects at an early stage which in turn saves the effort and cost as well. It ensures that the integrated modules work properly as expected.

Focusable Action Detector In Flutter

Whenever you will code for building anything in Flutter, it will be inside a widget. The focal design is to assemble the application out of gadgets. It depicts how your application view should look with its ongoing design and state. Right when you made any change in the code, the gadget adjusts its portrayal by working out the separation between the past and current widget to pick the irrelevant changes for conveying in the UI of the application.

In Flutter, to build any application, we start with widgets. The construction block of flutter applications. Widgets portray what their view should look like given their current setup and state. It consolidates a text widget, line widget, segment widget, container widget, and some more.

While building a custom UI control in Flutter it’s enticing to simply utilize a GestureDetector and tap out, yet to do so would be a mix-up! Particularly assuming you’re anticipating supporting clients with alternate inputs like a mouse or keyboard.

In this article, we will explore the Focusable Action Detector. We will implement the Focusable action detector demo program and learn how to use the same in your flutter applications.

FocusableActionDetector class – widgets library – Dart API
API docs for the FocusableActionDetector class from the widgets library, for the Dart programming language.api.flutter.dev

Conclusion

Incidentally, making a UI control that acts “appropriately” for different input sources is a lot more confounded than simply detecting taps. Generally, the control you make needs the accompanying features:

  • > a hover state
  • > a focus state (for tab-key or arrow-key traversal)
  • > a region that changes the mouse-cursor
  • > key handlers for [Space] and [Enter] keys (or maybe others)

Focusable Action Detector:

FocusableActionDetectorcombinesFocus,Actions,Shortcuts andMouseRegioninto one, and is used pretty heavily inside of the Flutter SDK, including the Material DatePicker,Switch,Checkbox,RadioandSlider controls.

Customarily, you could make that by making a significant block out of widgets including Focus, Actions, Shortcuts, and MouseRegion. This works, however, is a ton of boilerplate, and space. Fortunately, Flutter gives a committed widget for this purpose: FocusableActionDetector.

Demo Module :

This demo shows how the detector works in an app. It shows how the buttons are having focus and hover changes and mouse changing regions.

Constructor:

To utilize Focusable Action Detector, you need to call the constructor underneath:

FocusableActionDetector({
Key key,
bool enabled = true,
bool autofocus = false,
FocusNode? focusNode,
bool descendantsAreFocusable = true
,bool descendantsAreTraversable = true
,Map<ShortcutActivator, Intent>? shortcuts,
Map<Type, Action<Intent>>? actions,
ValueChanged<bool>? onShowFocusHighlight,
ValueChanged<bool>? onShowHoverHighlight,
ValueChanged<bool>? onFocusChange,
MouseCursor mouseCursor = MouseCursor.defer,
@required Widget child,
});

In Above Constructor all fields marked with @required must not be empty.

Properties:

There are some properties of FocusableActionDetector:

  • > actions → Map<Type, Action<Intent>>?A map of Intent keys to Action<Intent> objects that defines which actions this widget knows about.
  • > autofocus → bool True if this widget will be selected as the initial focus when no other node in its scope is currently focused.
  • > child → Widget The child widget for this FocusableActionDetector widget.
  • > descendantsAreFocusable → bool If false, will make this widget’s descendants unfocusable.
  • > descendantsAreTraversable → bool If false, will make this widget’s descendants untraversable.
  • > enabled → boolIs this widget enabled or not.
  • > focus Node → FocusNode?An optional focus node to use as the focus node for this widget.
  • > mouse Cursor → MouseCursorThe cursor for a mouse pointer when it enters or is hovering over the widget.
  • > onFocus Change → ValueChanged<bool>?A function that will be called when the focus changes.
  • > onShowFocusHighlight → ValueChanged<bool>?A function that will be called when the focus highlight should be shown or hidden.
  • > onShowHoverHighlight → ValueChanged<bool>?A function that will be called when the hover highlight should be shown or hidden.
  • > shortcuts → Map<ShortcutActivator, Intent>?The map of shortcuts that the ShortcutManager will be given to manage.

How to implement code in dart file:

You need to implement it in your code respectively:

Create a new dart file calledbutton.dart inside thelib folder.

To start with, make a StatefulWidget that can hold your _isFocused and _isHovered state. We’ll likewise make a FocusNode that we can use to demand focus on press, which is a typical way of behaving for buttons. Likewise, make some run of the mill onPressed and label fields to design the button.

class MyCustomButton extends StatefulWidget {
@override
State<MyCustomButton> createState() => _MyCustomButtonState();
}

class _MyCustomButtonState extends State<MyCustomButton> {
bool _isHovered = false;
bool _isFocused = false;
FocusNode _focusNode = FocusNode();

@override
Widget build(BuildContext context) {
// TODO:
}

void _handlePressed() {
_focusNode.requestFocus();
widget.onPressed();
}
}

Because we’re making a button, we’ll add some basic configuration options:

const MyCustomButton({Key? key, 
required this.onPressed, 
required this.label}) : super(key: key);
final VoidCallback onPressed;
final String label;
final Color color1;
final Color color2;

When we run the application, we ought to get the screen’s output like the underneath screen capture.

All that’s left now, is to fill out the build() method.

Widget build(BuildContext context) {
Color outlineColor = _isFocused ? Colors.black : Colors.transparent;
Color bgColor = _isHovered ? widget.color1 : widget.color2;
return GestureDetector(
onTap: _handlePressed,
child: FocusableActionDetector(
mouseCursor: SystemMouseCursors.click,
onShowFocusHighlight: _handleFocusHighlight,
onShowHoverHighlight: _handleHoveHighlight,
actions: {
ActivateIntent:
CallbackAction<Intent>(onInvoke: (_) => _handlePressed()),
},
shortcuts: const {
SingleActivator(LogicalKeyboardKey.keyZ, control: true):
ActivateIntent(),
},
child: Container(
padding: const EdgeInsets.all(8),
child: Text(widget.label),
decoration: BoxDecoration(
color: bgColor,
border: Border.all(color: outlineColor, width: 2),
),
),
),
);
}

In the above code, note that you still do need to wrap a GestureDetector to detect taps. Additionally, notice how you can change the appearance of your UI, according to the hover/focus state.

keyboard actions:

The final step for any control is Keyboard bindings. By default, most OS controls support [Space] and [Enter] to “submit”. You can do this by wiring up the built-in ActivateIntent in the .actions field:

FocusableActionDetector(
actions: {
ActivateIntent: CallbackAction<Intent>(onInvoke: (_) => _handlePressed()),
},
child: ...
),

You can also add additional key bindings using the .shortcuts parameter. Here we’ll bind yet [Ctrl + Z] to the same ActivateIntent. Now our control will submit on [Enter], [Space] and [Ctrl + Z]!

FocusableActionDetector(
shortcuts: {
SingleActivator(LogicalKeyboardKey.keyZ, control: true): ActivateIntent(),
},
child: ...
),

When we run the application, we ought to get the screen’s output like the underneath screen capture.

With that, you have a finished control that works exactly as you’d expect on desktop, web, and mobile! keyboard actions

Code File:

import 'package:flutter/material.dart';
import 'package:flutter/services.dart';

class MyCustomButton extends StatefulWidget {
const MyCustomButton(
{Key? key,
required this.onPressed,
required this.label,
required this.color1,
required this.color2})
: super(key: key);
final VoidCallback onPressed;
final String label;
final Color color1;
final Color color2;

@override
State<MyCustomButton> createState() => _MyCustomButtonState();
}

class _MyCustomButtonState extends State<MyCustomButton> {
bool _isHovered = false;
bool _isFocused = false;
final FocusNode _focusNode = FocusNode();

void _handleFocusHighlight(bool value) {
setState(() {
_isFocused = value;
});
}

void _handleHoveHighlight(bool value) {
setState(() {
_isHovered = value;
});
}

@override
Widget build(BuildContext context) {
Color outlineColor = _isFocused ? Colors.black : Colors.transparent;
Color bgColor = _isHovered ? widget.color1 : widget.color2;
return GestureDetector(
onTap: _handlePressed,
child: FocusableActionDetector(
mouseCursor: SystemMouseCursors.click,
onShowFocusHighlight: _handleFocusHighlight,
onShowHoverHighlight: _handleHoveHighlight,
actions: {
ActivateIntent:
CallbackAction<Intent>(onInvoke: (_) => _handlePressed()),
},
shortcuts: const {
SingleActivator(LogicalKeyboardKey.keyZ, control: true):
ActivateIntent(),
},
child: Container(
padding: const EdgeInsets.all(8),
child: Text(widget.label),
decoration: BoxDecoration(
color: bgColor,
border: Border.all(color: outlineColor, width: 2),
),
),
),
);
}

void _handlePressed() {
_focusNode.requestFocus();
widget.onPressed();
}
}

Conclusion:

In the article, I have explained the essential construction of the Focusable Action Detector widget in a flutter application; you can alter this code as indicated according to your choice. This was a little prologue to the Focusable Action Detector widget on User Interaction from my side, and its functioning utilizing Flutter.

I hope this blog will provide you with sufficient information on Trying up the Focusable Action Detector widget in your flutter projects. We showed you what the Focusable Action Detector widget is?, its constructor, and its properties of the Focusable Action Detector widget. We made a demo program for working Focusable Action Detector widget. So please try it.

Implement Obx In Flutter

Flutter is awesome! It’s by far the fastest way to create truly cross-platform apps without compromising beauty, performance, and features. With development experience unlike any other framework, it does tick most of the boxes. However, it’s not perfect. Some things slow down the development from time to time.

If you’re looking for the best Flutter app development company for your mobile application then feel free to contact us at — support@flutterdevs.com.

Enter GetX!:

GetX is a micro-framework that aims to provide a top-notch development experience by minimizing the boilerplate combined with neat syntax and a simple approach. When developing with GetX, everything feels self-evident and practical. It’s a solid blend of simplicity and power. It’s one of those rare packages that try to do everything and do it.

GetX provides a combination of State Management, Dependency Injection, and Route Management solutions that work great together. But things don’t end here, it provides a ton of utilities that make it easy to implement internationalization, theming, validation, etc.

All of these solutions and utilities are packed in individually compiled containers which give us the freedom to choose what to use and what not to, without compromising performance. However, once you’re using GetX, it’s hard to not use everything this package has to offer because everything works so seamlessly together. And, that’s what I call The GetX Ecosystem.

What’s so special?:

  • Firstly, I love the syntax! Before I used GetX, I couldn’t imagine that things like navigating a route can be made this simple. We don’t need, a builder or anything. Just write Get.to(SomePage()) and that’s it. And that’s just one example.
  • The primary focus is on performance. Normally, we would have to choose which controllers to dispose of and manually dispose of them. With GetX, it’s the opposite. We have to choose which one to keep in the memory as they are disposed of automatically. Saves memory, and lines of code.
  • 100% Decoupling! With GetX, it’s possible to achieve this. Business logic is separated from views, and even dependencies can be separated using something called Bindings.
  • It just works. Working with GetX is quite a satisfying experience. Whenever I’ve to implement a certain feature, there’s always a simpler way to do it with GetX, no matter the use case.
  • It’s well maintained and up-to-date. It can be challenging to keep all your packages updated and in sync with each other. Sometimes, there are breaking changes and things can get nasty. GetX centralizes most of our development needs under one package, so we don’t need to worry about compatibility and maintenance.

Let’s Start:

State Management? State Management!:

State Management is still the hottest topic in Flutter Community. There are tons of choices available and it’s super intimidating for a beginner to choose one. Also, all of them have their pros and cons. So, what’s the best approach? The answer is simple — The one you feel comfortable with. Can GetX be the one? Let’s take a look!

GetMaterialApp:

Step 0: Use GetMaterialApp instead of MaterialApp.

class MyAppState extends State<MyApp> {
@override
Widget build(BuildContext context) {
return GetMaterialApp(
localizationsDelegates: context.localizationDelegates,
supportedLocales: context.supportedLocales,
locale: context.locale,
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: const MyHomePage(title: 'Easy localization'),
);
}
}

Boom! Now you’re officially in the ecosystem.

GetxController:

Controllers are classes where all our business logic goes. All the variables and methods are placed here and can be accessed from the view. While we can just create a simple class for this purpose, GetX provides a class called GetxController which extends DisposableInterface.

This means that our controller will get deleted from memory as soon as the widgets using it are removed from the navigation stack. We don’t have to manually dispose of anything and the memory consumption is reduced, resulting in high performance.

class Controller extends GetxController {
TextEditingController ctrl = TextEditingController();
var buttonName = "edit".obs;
void upDate() {
if (ctrl.text.isNotEmpty) {
buttonName.value = 'Save';
} else {
buttonName.value = 'Edit';
}
}

void goToNexPage() {
if (ctrl.text.isNotEmpty) {
ctrl.clear();
upDate();
Get.to(() => const SecondScreen());
}
}
}

Add .obs to any variable and you make it observable. You’re turning buttonName type String. This means that we can listen to the changes made to buttonName our view using GetX.

We use update() the method inside any method in the controller so that our widgets can listen to the changes made by the method. If you have used the Provider package, it’s just like notifyListeners().

Obx:

This one is a personal favorite. It has the simplest syntax and implementation. All we’ve to do is wrap the widget in Obx(() ⇒ ) and we’re done!

_buildButtonView() {
return GestureDetector(
onTap: ()
{
controller.goToNexPage();
},
child: Container(
height: 67,
alignment: Alignment.center,
decoration: BoxDecoration(
color: Colors.blue,
borderRadius: BorderRadius.circular(20),
),
child: Container(
alignment: Alignment.center,
padding: const EdgeInsets.symmetric(horizontal: 10),
child: Obx(
() => Text(
controller.buttonName.value,
textAlign: TextAlign.center,
style: const TextStyle(color: Colors.white, fontSize: 20),
),
),
),
),
);
}

The syntax is shorter than, setState though there’s one extra step here. We need to initialize the Controller to use our variables and methods.

This is how we do it in GetX:

final controller = Get.put(Controller());

Release Build Process In Flutter

Hi everyone! today I am back with a new topic let’s start learning about the release build process in a flutter, Software Build and Release refers to the specialized subfield of system administration that focuses on the process of building software from source code for (initially) testing and (ultimately) releasing and distributing the software.

Conclusion

What is the difference between build and release?:

A “build” is given by the dev team to the test team. A “release” is the formal release of the product to its customers.

A build when tested and certified by the test team is given to the customers as a “release”. A “build” can be rejected by the test team if any of the tests fail or it does not meet certain requirements. One release can have several builds associated with it.

What is Build and Release Management:

Build and release management is the process of managing, planning, scheduling, and controlling a software build throughout its lifecycle.

Building an application or software includes different stages. Each build has different build numbers and it is constantly worked from a source code storehouse like git. Building an application or programming requires assembling apparatuses like a subterranean insect, expert, Gradle, and so forth. Assemble instruments incorporate the source code records into reusable executable documents or bundles.

Build and Release the executives will control the existing pattern of a product item, the most common way of arranging, making due, planning, and controlling the form in various stages and conditions like the turn of events, testing, organizing, and creation stages.

There are 5 types of environments in build and release infrastructure :

  • DEV — The development team keeps up with this climate to compose their code. Just the development team has access to this environment. QA or different groups don’t approach this environment. Dev group uses this environment, for the most part, to write unit test cases.
  • QA — QA environment is owned by the testing group and the real testing happens in this environment. The DEV group doesn’t approach the QA environment. After coding is finished, the code is moved from DEV to the QA environment for test execution.
  • UAT — User Acceptance Test environment is used by business users to conduct testing after system testing has been completed. In this phase, the product is tested from the business point of view. UAT environment access is restricted only to the business users and on some occasions, temporary access will be provided to the QA team if in case of business users need assistance.
  • STAGING — The STAGING environment exactly resembles the production environment. The application installed in the staging environment should match closely with the production environment.
  • PROD — The PROD environment is the production environment that is accessed by real users and none of the DEV and QA teams have access to this environment.

Overview:

To ensure your app works in deployment, test your release build in a variety of conditions before submitting the app or app update for review, or distributing to Enterprise users. To catch commonly occurring errors or edge-case situations that might not occur during development, consider the differences between development-environment debug builds and user-environment release builds, shown below.

An app may behave differently on a particular user’s device for a variety of reasons. Different devices and operating system versions offer varying software features, and app updates involve data migrations, keychain access, or default data that are not present in a fresh app installation. Disabled features, frame throttling, or other delays may result in limited device power, system memory, or network availability. Xcode allows development and release build settings to diverge, and disables watchdog timeouts.

Create an Xcode Archive:

To test the specific states of your application client’s insight, make a delivery fabricate. In your Xcode undertaking’s plan supervisor, set the run objective to a device and change the chronicle errand to the Release configuration.

Then, choose the Archive option in Xcode’s Product menu. After the archive builds, the Organizer displays.

Xcode saves app archives on disk so you can refer to a particular build later, for example, to submit the build to App Review after the app passes beta tests. The archives’ distribution workflow offers several ways to test the app:

  • TestFlight — TestFlight automates app distribution and submission to reduce the chances of submitting the wrong build to App Review. To distribute an app archive through TestFlight, choose the archive pane’s App Store Connect option.
  • Ad Hoc — To distribute your app to testers manually, for example, by emailing them an .ipa file, choose the archive pane’s Ad Hoc option.
  • Enterprise — Enterprise distribution is similar to Ad Hoc distribution except that you choose the Enterprise option from the Archive pane. Xcode looks for a different code signing identity for Enterprise app distribution that contains a valid Enterprise distribution certificate.
  • Development — The development distribution method signs the release build with your development credentials. This option enables testing if you lack access to team distribution identities. The debugger can attach to a development-signed release build, but be aware that it can mask watchdog timeouts.

For all distribution methods except TestFlight, choose the following options to enhance your chances of discovering a bug that manifests only in the release build:

  • Set App Thinning to “All compatible device variants”.
  • Check “Rebuild from Bitcode”.

You can access an app archive after distribution to debug a user-reported error. If the issue didn’t surface in beta tests, refer to crash logs and app logging to track down the cause; To attempt to reproduce the issue, check the build version in the crash log, and test a release build from an app archive with a matching version.

Compare Build Configuration Settings:

The Xcode project’s Build Settings support various qualities in light of the dynamic form design. The default build configuration are Debug and Release, which the venture plot guides to the Run errand and Archive task, individually. Since the chronicle task makes the delivery construct, the delivery fabricate can act uniquely in contrast to the form that designers run in the debugger as it connects with fabricate settings.

By default, most build settings match the two configurations. To check for differences, inspect the target’s build settings thoroughly. When a setting varies across configurations, Xcode displays <Multiple values>. To see each value, expand the setting’s disclosure triangle.

To ensure the app’s behavior differs across build configurations as intended, take a moment to consider the full implications of each difference, per setting. In the figure above, the app defines a different Info.plist for the release build.

Disconnect the Debugger:

When Xcode launches an app, it enables a debugger that creates some differences from what users experience:

  • The Xcode debugger disables watchdog terminations, which can prevent testers from observing a hang issue while running the app in Xcode. The easiest way to check for watchdog terminations is to disconnect the device from the development machine and launch the app from the home screen.
  • Xcode’s debugger prevents apps from being suspended, so launch your app from the home screen to test background processes. For example, NSURLSession implements a background session, but when the app runs in the Xcode debugger, the background session never runs.

Test a Fresh Install and App Update:

Xcode enhances application building and establishment during improvement by refreshing applications steadily. Thusly, as your application’s code changes during improvement, outdated put away information made by an earlier form might wait except if you cleanse the earlier establishment totally. Despite the fact that the application may never again make old information, admittance to it might cause the application to act contrastingly during testing than what clients experience. To forestall this transient reliance, eliminate the application during improvement to guarantee that Xcode introduces a new form. At the point when you eliminate the application, decide to likewise eliminate the application’s earlier information.

There are two exceptions:

  • The system preserves App Group data on the device as long as the app in the group is installed. To remove potentially obsolete test data from an App Group container, remove all apps that share the group.
  • The system preserves an app’s keychain data on the device even after you delete the app. To clear the keychain, use secItemDelete(_:). If you create a separate utility that removes keychain data, the utility and the app need to share the same application identifier.

If the release build updates a previous version of your app, some users may have the prior version on their device. When your app update aims to support data created by the prior version, test the app update to prevent any regressions. For example, if the updated app changes a file format, or migrates prior data, test the app-update scenario to ensure that the new app properly handles prior app data.

Run the App on Various Devices and OS Versions:

An error may surface only on a particular device, OS version, or a particular combination of the two. To ensure a consistent user experience, test on a wide array of devices and OS versions your app supports.

When diagnosing user-reported issues, pay attention to the user’s device and OS version. See Hardware Model and OS Version in Examining the Fields in a Crash Report. To reproduce a user-reported issue, maintain a robust suite of test devices that vary in device model and OS version. Although it’s possible to run a release build in the Simulator, consider the Simulator a separate device that users don’t use. As such, always test release builds on an actual device.

Check File System Access:

On macOS, users can have different levels of file system access depending on their user account privilege. One way to test the difference that a user’s account privilege makes in your app is to run the app as a guest user. The file system privileges of a guest user fall under the everyone category in Finder’s Get Info pane. By default, the file system access level everyone differs from the default admin access level.

Ensure Network Compatibility:

Debug builds typically run in an isolated network during development, whereas release builds access to varying networks that service your app’s users. Your app can exhibit a problem in one particular network and not another, for example, due to network congestion or network type, such as IPv6 versus IPv4.

  • If developers and beta testers run the app in an IPv4 network, be sure to also test an IPv6 connection to catch any potential issues related to DNS64 or NAT64.
  • To simulate slow or unreliable internet connections on iOS, you can use the Network Link Conditioner. Enable this feature with the Settings app > Developer > Network Link Conditioner option.
  • To debug high-level HTTP issues, run your release build with an HTTP debugging proxy. For low-level issues, like a TCP connection or DNS failure, examine network-level activity for causes.
  • To debug lost network connections, ensure that network connections reach their destination with no breakdowns along the way by reviewing your server-side logs. For private networks, consider potential blockages due to firewall configuration, network proxies, or load balancers.

Some network errors are unavoidable, for example, during server or network downtime. Ensure that your app provides clear user instructions on what to do when the network doesn’t function as expected.

Enable Battery-Saving Modes:

Devices can behave differently based on battery level, the amount of time passed since fully charged, or whether the device battery is charging. For example, Core Location enables an app to request a desired accuracy but it may perform less accurately than your app requests depending on the device battery level. Alternatively, if a concurrent app or system process requests a high accuracy, Core Location might provide a higher accuracy than requested, which may consume the device battery faster. To observe an app error that might result from a lower battery level, or lower Core Location accuracy than your app expects, test under either battery-saving mode:

  • On macOS, run the app on a Macbook unplugged from the power source.
  • On iOS or iPadOS, enable Low Power Mode in Settings > Battery.

To ensure the device is in Low Power Mode, check that the battery indicator is yellow.

Minimize Memory Use:

A user’s device may have less memory available at runtime than testers do either because of varying hardware specifications or the number of apps the device runs concurrently. To simulate an array of user environments, testers need to vary the amount of memory available to your app. One way to limit available memory is to open other apps. On macOS, you can observe memory statistics using Activity Monitor. The difference between the Physical Memory and Memory Used values equals the system’s available memory.

Apps that crash due to memory depletion generate a different kind of crash report, called a jetsam event report.

The volatile nature of memory availability makes it difficult to judge the likelihood of a jetsam event in your app. A good strategy to guard against runtime memory depletion is to proactively minimize your app’s memory requirements using Instruments or MetricKit.

Support User-Defined Input:

Because of the wide range of variation in user-supplied data, apps that support opening users’ files need to anticipate uncommon scenarios, like corrupt or excessively large data. To ensure a good user experience, test bad and unsupported files.

Test Regions and Languages:

The Region user preference setting determines the format of the dates that the OS provides to your app. When a user changes their Region, the system changes the format of every NSDate it supplies to your app. If your app processes dates or times test every language that your app supports to ensure your app can handle all of the possible date formats.

Conclusion:

There is a distinct difference between Build and Release although these two words are often used interchangeably. The main difference between Build and Release in Software Testing is that Build is a version of the software the development team hands over to the testing team for testing purposes while Release is the software the testing team hands over to the customer.

Equatable In Flutter

We all know we can compare two things with “==” this operator, but do you know how to compare two instances of the same class?. Well, it is quite a lengthy process, comparing each instance by overriding “==” and hashCodes, and to simply that exact process we have Equatable.

In this article, we will explore Equatable In Flutter. We will implement the Equatable demo program and learn how to use the same in your flutter applications.

Equatable:

The Equatable is used to simplify the process of comparing instances of the same object without the need for boilerplate codes of overriding “==” and hashCodes.

Using flutter equatable we can Simplify Equality Comparisons in order to compare different instances of the same class we have to override the == operator as well as hashcode. By default, == returns true if two objects are the same instance of the class.

Code Implement:

Step 1: Add the dependencies

Add dependencies to pubspec — yaml file.

dependencies:
equatable: ^2.0.3

Step 2: Import

import 'package:equatable/equatable.dart';

Step 3: Run flutter packages get in the root directory of your app.

How to implement code in dart file :

You need to implement it in your code respectively:

Create a new dart file called phone.dart inside the lib folder.

class Phone {
final String phoneName;
final String phoneImage;

const Phone({
required this.phoneName,
required this.phoneImage,
});
}

Also, Create a new dart file called main.dart inside the lib folder.

We create two phone objects,

final Phone samsung = const Phone(
phoneName: 'Samsung S20 FE 5G',
phoneImage: 'assets/phone1.jpeg',
);
final Phone iphone = const Phone(
phoneName: 'Iphone 11',
phoneImage: 'assets/phone2.jpeg',
);

Now if we try to compare these two objects, they will never be the same,

Output

but if we create two same objects,

final Phone iphone = const Phone(
phoneName: 'Iphone 11',
phoneImage: 'assets/phone2.jpeg',
);
final Phone iphone2 = const Phone(
phoneName: 'Iphone 11',
phoneImage: 'assets/phone2.jpeg',
);

and compare the two still, they are not the same because under the hood Dart doesn’t compare the objects by their value.

Output

here iPhone and iphone2 both objects are in different memory locations. It doesn’t matter if they have the same values. They both will be considered as different objects.

So, what can we do now?

Let’s use equatable for comparing two instances of the same object,

First, we extend the existing class with Equatable, and then override a getter method props.

import 'package:equatable/equatable.dart';

class Phone extends Equatable {
final String phoneName;
final String phoneImage;

const Phone({
required this.phoneName,
required this.phoneImage,
});

@override
List<Object?> get props => [phoneName, phoneImage];
}

Note: Equatable is designed to only work with immutable objects so all member variables must be final.

That’s it!!

Output

Now the two objects are the same based on their values, the prop property of the equatable is further explained below.

Property:

Equatable comes with props property which has its own purpose in object comparison.

Props property decides which objects we should consider for object comparison.Props is a getter method that will return List<Object>. HereObject can be of any type (like : int,double, list etc). You have to simply return a list of all the objects that are available in your class, (phoneName and phoneImage in our case).

Uses:

Equatable is useful in many cases, one of which is with flutter_bloc

In Bloc, we have to extend Equatable to States and Events classes to use this functionality. This helps us when it comes to stream as we need to decide state updation based on it.

For example,

abstract class FetchUserState extends Equatable {}

FetchUserState will not make duplicate calls and is not going to rebuild the widget if the same state occurs. Now, think if we hadn’t used Equatablehere, then how many times the widget will be rebuilt?

Code File:

import 'package:equatable_example/phone.dart';
import 'package:flutter/material.dart';

void main() {
runApp(const MyApp());
}

class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);

@override
Widget build(BuildContext context) {
return MaterialApp(
debugShowCheckedModeBanner: false,
title: 'Flutter Demo',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: const MyHomePage(),
);
}
}

class MyHomePage extends StatefulWidget {
const MyHomePage({Key? key}) : super(key: key);

@override
State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
final Phone samsung = const Phone(
phoneName: 'Samsung S20 FE 5G',
phoneImage: 'assets/phone1.jpeg',
);
final Phone iphone = const Phone(
phoneName: 'Iphone 11',
phoneImage: 'assets/phone2.jpeg',
);
final Phone iphone2 = const Phone(
phoneName: 'Iphone 11',
phoneImage: 'assets/phone2.jpeg',
);

comparePhone(BuildContext context) {
if (iphone == iphone2) {
ScaffoldMessenger.of(context)
.showSnackBar(const SnackBar(content: Text("YES, They are EQUAL")));
} else {
ScaffoldMessenger.of(context).showSnackBar(
const SnackBar(content: Text("NO, They are not EQUAL")));
}
}

@override
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: Colors.teal,
appBar: AppBar(
automaticallyImplyLeading: false,
title: const Center(child: Text('Equatable Example')),
),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: [
phoneWidget(
phoneName: iphone.phoneName, phoneImage: iphone.phoneImage),
ElevatedButton(
style: ButtonStyle(
backgroundColor: MaterialStateProperty.all(Colors.green),
),
onPressed: () {
comparePhone(context);
},
child: const Text("Compare"),
),
phoneWidget(
phoneImage: iphone2.phoneImage,
phoneName: iphone2.phoneName,
),
],
),
),
);
}

phoneWidget({
required phoneImage,
required phoneName,
}) {
return Column(
children: [
Image.asset(phoneImage),
const SizedBox(height: 5),
Text(
phoneName,
style: const TextStyle(
fontSize: 15,
fontWeight: FontWeight.w800,
),
),
],
);
}
}

Conclusion:

In the article, I have explained the essential construction of the Equatable in a flutter application; you can alter this code as indicated according to your choice. This was a little prologue to the Equatable package on User Interaction from my side, and its functioning utilizing Flutter.

I hope this blog will provide you with sufficient information on Trying up the Equatable package in your flutter projects. We showed you what the Equatable package is? its properties of the Equatable package. We made a demo program for working Equatable package. So please try it.

Conclusion

What is Automation Testing?:

Automation Testing is the method of testing software products with special testing tools and frameworks to minimize human intervention and maximize quality.

Automation Testing is finished with the assistance of computerization programming, and it controls the progression of the execution of tests according to the composed test scripts. They are then contrasted with anticipated results to guarantee the quality and dependability of the application. With Automation Testing, one can perform essential monotonous errands and those assignments that are difficult to accomplish with manual testing. Hence, this kind of testing is basic for CI/CD pipelines.

Why Automation Testing?:

At the point when an organization develops an item, having defects is bound. In this way, before the arrival of the item, the organization needs to catch the defects in it to give a consistent client experience. The testing group must perform different sorts of testing, from practical to non-functional, to guarantee the viability, effectiveness, and better client experience of the general item.

However, testers do both Manual and Automation testing, doing Automation Testing facilitates a ton of manual work, gives precise outcomes, and sets aside a ton of time, which results in the faster delivery of the item.

Automation Testing Life Cycle:

To offer the best quality item, an association ought to circle back to the bit by bit Automation Testing life cycle to pull off outcomes on the market. Take a look at the below image that shows the six phases of Automation Testing:

The Scope of Automation Testing:

Before completing the testing system, one should check for the possibility of Automation. Here are what to consider while distinguishing the extent of Testing Automation:

  • What are the modules that can be automated?
  • What are the total effective costs and the team size?
  • What are the tests to be automated, and which is the approach to be taken?

The Right Automation Tool:

Automation Testing is beyond the realm of possibilities without the right testing device. Choosing the right device is a basic stage in the testing life cycle where one needs to think about the accompanying focuses:

  • Familiarity with the tool among the resources on-board
  • Total budget and flexibility
  • Technologies and programming languages used to build the project
  • Choosing a tool that has a support team to take care of any queries and issues

Automation Test Plan, Design, and Strategy:

As the name recommends, in this stage, you make an arrangement, plan the engineering, and formulate a procedure to accomplish the objective of test Automation.

  • Test plan: Creation of test principles and strategies, hardware, programming, and test information prerequisites
  • Test design: Design the test architecture to determine the flow of the test procedures that follow
  • Test strategy: Select a suitable test automation framework

Setting up the Test Environment:

You want to set up a remote machine or a machine where the test cases can be run. It ought to cover a broad test inclusion range for various test situations, various programs, support work areas, and mobile applications.

Automation Test Script Execution:

In this step, you will execute the test scripts and check regardless of whether the contents run accurately. This step includes every one of the utilitarian angles and similarities across numerous stages. You likewise need to create a bug report if the test case fails.

Analysis and the Generation of Test Results and Test Reports:

This is the last phase of the testing life cycle. Here, you will dissect the test reports to decide if they need extra testing or not. Then, the age of test results outcomes is finished to affirm assuming the test contents can recognize mistakes in the application. At long last, the test reports are imparted to the individuals/clients who are involved in the project.

Types of Automation Testing:

At the point when you are given an item, the information on automation types will help you to conclude which sort of test suites you can use for Automating. Automation Testing can be isolated into three classifications as given below:

1) Automation Testing Based on the Types of Testing:

Now, you can check out the types of Automation Testing in the following section.

> Functional Testing

Functional testing is about what the item does and checks each capability/element of the application. It depends on clients’ prerequisites. With useful testing, you approve the activities that you act in the product. It tends to be done Manually as well as automated. An example of functional testing is testing the login functionality of a website.

> Non-functional Testing

Non-functional testing is about how the item acts and checks the non-functional perspectives, like execution, unwavering quality, convenience, and so forth, of the item. It depends on clients’ assumptions. With non-functional testing, you approve the presentation of the product. It is difficult to Manually do. An example of non-functional testing is testing how long it takes for the dashboard in a website to load.

2) Automation Testing Based on the Phases of Testing:

> Unit Testing

A unit refers to the smallest part of the product. For the whole item/programming to function admirably, it is fundamental that every one of the singular pieces of the code fill in as required. Unit testing gives a granular perspective on how the code is performing. It has a quicker execution time since you are trying just lumps of code at a time. As a rule, engineers like to perform unit testing.

> API Testing

API stands for Application Programming Interface. It acts as a middle interface between the UI and the database.

API testing checks the end-to-end functionality of the application. Here, testers will not have access to the source code, and the process does not involve inputs and outputs from the keyboard. Instead, the software is made to send API calls to get the output, and the testers note the system/application response to check the functionality.

> UI Testing

In UI testing, the testers search for the accuracy of the visual components, for example, fields, buttons, names, joins, text fields, and pictures on the framework’s screen. These components should be shown accurately and function as expected for a superior client experience. UI testing additionally checks for the usefulness of the application in dealing with client activities, which are done using their console, mouse, and other information gadgets. Its principal aim is to give a well-disposed UI (UI) and experience.

3) Automation Testing Based on the Types of Tests:

Below is a list of the tests that are common in the field of automation:

> Smoke Testing

Smoke testing is otherwise called build verification testing (BVT). It is finished in the underlying phases of use testing. At the point when you add another component or usefulness to the current form, smoke testing is done that goes about as a designated spot to continue toward a higher degree of testing.

> Integration Testing

Integration testing is also called I&T testing or string testing or rarely thread testing. It is to approve the appropriate correspondence between every one of the modules of the application. All in all, since the product is comprised of a ton of more modest modules, in integration testing, testers legitimately bunch them and test them as gatherings to uncover the defects while keeping up with the communication between these software modules.

> Regression Testing

To be sure if the developed and tested software works the same way after changes have been made, then, at that point, you perform regression testing. The progressions can be bug fixes, arrangement changes, or the improvement of the product. You accomplish this by re-running functional and non-functional tests on the application.

> Security Testing

As a tester, you would rather not cause information breaks, loss of income, and a disaster for notoriety because of unapproved access. To keep away from such episodes and forestall malignant interruption, security testing is finished, which disentangles the basic hazardous strings, weaknesses, dangers, malware, and different dangers in the product application. Security testing assists you with detecting every one of the weaknesses and fragilities in the framework’s security, which you can forestall opportune by thinking of viable arrangements.

> Performance Testing

Regardless of whether your item gets a weighty responsibility, it requirements to work without slack. Thus, you want to test your item before sending off it to the clients to look at its responsiveness, speed, dependability, unwavering quality, and strength under a specific responsibility. An example of performance testing is checking the program reaction time and the server demand handling time.

> Acceptance Testing

Acceptance testing is the last phase of testing before sending off the item into the market. It is finished to ensure all the client needs, business necessities, and the client’s requests are met and to decide whether the item is good for delivery or not.

Testing Frameworks:

Let’s learn about testing frameworks and their types:

A testing framework does only this during the testing system. It has a bunch of rules for the experts that incorporate coding guidelines, store the board, and treatment of test information to come by recipient results, for example, simple code reuse, diminished opportunity to oversee contents, and high movability.

Here are the commonly used testing frameworks:

> Linear Framework

This is the simplest structure of all. Under this framework, you want to compose a basic code to run the experiments with no measured quality of successive advances. It fills in as a record-and-playback model.

> Keyword-driven Framework

It is a scripting technique where you associate keywords with specific activities, for example, opening or shutting of a program, mouse-click events, and others. Later on, in your test scripts, you can call these keywords to perform a particular step. Also, you will have a file where you will maintain all the keywords, alongside the activities they perform.

> Data-driven Framework

In a data-driven framework, all the test case data inputs are put away in the table or extension files, including .xls, .xml, .csv, and so forth. While executing the test scripts, it will peruse the qualities from the table. With the assistance of this structure, you can perform both positive and negative test cases.

> Page Object Model Framework

In the POM framework, you will make an article vault for the web UI components. It permits you to call these strategies later on without composing the code once more. Consequently, it brings about less verbosity, code reusability, and decreased time-utilization to write test scripts.

> Modular Framework

The modular framework permits you to isolate the test scripts into little, free modules. These modules will connect in various leveled ways to run enormous test scripts. This will likewise assist you with making the necessary test situations and testing the contents independently.

Automation Testing Tools:

An automation tool should be chosen based on the type of testing and the type of framework you will execute. There are a ton of devices accessible on the lookout for you to browse according to your necessities.

Some of the most widely used automation tools are listed below.

> Selenium

It is a tool to test web applications and web browsers. It has multiple powerful tools for testing web applications. Also, it supports multiple platforms and browsers.

> Sikuli

Sikuli is an open-source automation testing tool used to perform GUI testing.

> JMeter

It is a tool that is used for performance tests.

> QuickTest Professional (QTP)

Testers use QTP to perform automated regression testing to identify gaps between the actual and desired results and detect the errors/defects that the outcome has.

> JUnit and NUnit

These tools are used by professionals to perform unit testing.

> TestNG

TestNG is more like a framework than a tool, which supports Selenium, REST Assured, Appium, etc. Testers can generate HTML reports for the tests with their status — passed, failed, or skilled. Later on, they can re-execute the failed test cases.

> SoapUI

It is a testing tool used for API testing.

> Appium

It is a tool to perform mobile application testing and native app testing.

Benefits of Automation Testing:

If you are learning Automation Testing, you need to know the benefits of learning it. Like every other type of testing, Automation Testing has its pros and cons.

Here, you will learn about the 10 advantages of Automation Testing:

  • It proves to be reliable since it is carried out by efficient testing tools.
  • 70% faster than manual testing, which saves a lot of time for testers and the organization as a whole.
  • Automation Testing avoids human intervention while executing test scripts.
  • It allows re-usability and re-running of test cases.
  • It increases the speed and efficiency of the software testing process.
  • Automation Testing covers all the application features.
  • It also allows for the faster delivery of the product into the market.
  • Faster feedback systems, which come with Automation Testing, result in an easy communication flow between developers and testers and help detect and fix bugs earlier.
  • It offers improved accuracy as it holds no possibility of human errors.
  • It can run massive amounts of test cases at a time.

Conclusion:

Successful automation mandates a testing process. Just as a developer needs a system development process, testers need a testing process to successfully use test tools. The testing process provides the steps, guidelines, and techniques that will ensure practical, successful automation.

Explore Deep Linking in Flutter

Consider you have a web app or website, and two beautiful apps (Android and iOS) for making your product accessible to your customers. Now for some reason, the analytics shows the users are accessing the product information majorly via the browsers not just on the desktop, but also on the mobile.

Very often when a web app/ site is not mobile browser optimized, the user might find it really hard to get the information he/she is seeking which can lead to user drop-offs.

Why not redirect the users to the play store or app store and make them use the apps which are made just to provide an optimized mobile experience?

Oh yes! Why not?

But this can lead to another problem where the user downloads the app, but now he/she has to manually navigate to the products they were once interested in while hitting the URL on the mobile browser. This again breaks user experience which needs to be addressed.

URL’s

Assuming the deeplinkingdemoapp.page.link has an Android and an iOS app, the link should redirect you to one of these apps for a better user experience. If the app is already available on your device, there are high chances of you landing on the equivalent app screen if the concept of deep links (which is quite popular already) is implemented inside the apps.

But what happens if the app is not installed?

With Dynamic Links, users get the best available experience for the platform they open the link on. If the link is opened in iOS or Android browsers, it can be taken directly to the linked content in your native app. If a user opens the same link on a desktop browser, they will be taken to the equivalent content on your website or web app.

If a user opens a Dynamic Link on iOS or Android and doesn’t have the app installed, the user can be prompted to install it; then, after installation, your app starts and can access the link shared that was shared.

Dynamic links provide a way for deep links to survive the installation step in a way that the user never loses the context.

How are Dynamic links different from deep links?

A Dynamic Link is a deep link into your app that works whether or not your app is installed. It carries the following information:

  • Project information is available inside the Firebase Console.
  • The package name for the apps that it needs to target.
  • A fallback Url for redirection in those extreme cases where the app could not be installed.
  • And obviously, the deep link that the app should utilize to reach the web equivalent screen.

To add dynamic link support for the apps, we need to add our project in Firebase. This can be done directly from Android Studio:

Tools → Firebase

On the left side, the Firebase Assistant panel click on

Dynamic link → Add Dynamic Links

  • Adding intent filters in AndroidManifest.xml for the activity which will handle the deep links as:
<activity android:name=".MainActivity">
<intent-filter android:autoVerify="true">
<action android:name="android.intent.action.VIEW"/>
<category android:name="android.intent.category.DEFAULT"/>
<category android:name="android.intent.category.BROWSABLE"/>
<data android:host="example.com/link" android:scheme="http"/>
<data android:host="example.com/link" android:scheme="https"/>
<data
android:host="deeplinkingdemoapp.page.link"
android:scheme="https"/>
</intent-filter>
</activity>

> Now upon successful completion of the above steps, we can see our project in the Firebase console.

Firebase Console → Select your project → Dynamic links (Left side panel, under Grow) →Get Started

> Now click on the “New Dynamic link” button on the new page which will open:

  1. Add the deep link URL (URL for which the transition from the web page to the application is needed) as per your requirement. For our example, it will be: https://deeplinkingdemoapp.page.link/GoogleMapScreen

2. Provide app pieces of information to define link behavior for iOS and Android apps. The instructions for linking both Android and iOS apps are pretty much self-explanatory.

3. Click on create.

Now as we see there is another URL visible in the above screenshot :

  1. https://deeplinkingdemoapp.page.link/GoogleMapScreen

This is the dynamic link created which has all the information mentioned above, for it to be able to link (https://deeplinkingdemoapp.page.link/GoogleMapScreen) to our apps whether it is installed or not whenever the user hits the dynamic link on the mobile browsers.

Now the dynamic link has enough information about the app and it can open the app (if installed) or take the user to the play store or app store for app installation. And once the app is launched the deep link which can be retrieved from the dynamic link can be processed.

How to get deep link data from a dynamic link?

_handleDeepLinks() async {
final PendingDynamicLinkData? initialLink =
await FirebaseDynamicLinks.instance.getInitialLink();
if (initialLink != null) {
final Uri deepLink = initialLink.link;
print('Deeplinks uri:${deepLink.path}');
if (deepLink.path == '/ShowApiDataScreen') {
AppRoute.nextPage(
context,
ShowApiDataScreen(
deepLinkPath: '${deepLink.path}:Deep Link',
));
} else if (deepLink.path == '/GoogleMapScreen') {
AppRoute.nextPage(
context,
GoogleMapScreen(
deepLinkPath: '${deepLink.path}:Deep Link',
));
} else if (deepLink.path == '/UserSignUpScreen') {
AppRoute.nextPage(
context,
UserSignUpScreen(
deeplinkPath: '${deepLink.path}:Deep Link',
));
}
}
}

pendingDynamicLinkData will be https://deeplinkingdemoapp.page.link/GoogleMapScreen and pendingDynamicLinkData.getLink() returns the deep link (which will be https://deeplinkingdemoapp.page.link/GoogleMapScreen in our case) associated with the dynamic link received by the activity. Now, this deep link can be handled similarly to any other deep links that the app supports.

I hope this post will give you a basic idea of creating Firebase Dynamic Links and setting Firebase Dynamic Links SDK on Android.

Animating a Widget Across Screens In Flutter

Before figuring out how to animate widgets, we want to grasp the fundamentals of animations.

If you’re looking for the best Flutter app development company for your mobile application then feel free to contact us at — support@flutterdevs.com.

What are animations?

Animations are a fundamental and coordinated piece of any Flutter mobile application development organization like Aeologic Technologies, which adds to the regular and smooth working of the UI. The intelligent highlights and quick changes make it easy to understand and upgrade the client experience Flutter upholds different animation features for its consumers.

In this manner, it is significant to comprehend the basics of widget animations to convey an advanced client experience. Flutter SDK offers a few underlying animations for widgets.

The underlying animations presented by Flutter are Fade transition, Size transition, and slide transition. These widgets work by setting a beginning and end point. On the off chance that your picture doesn’t match the current devices, you can utilize the custom option.

  1. Fade Transition
    By changing the haziness of a widget, you might blur it in and out with Fade Transition. You should set opacity values in the Animation Controller at the underlying stage. One should give an opacity border with animation and a child widget in the animation code.

2. Size Transition
The size transition permits one to change the widget’s height, width, and alignment. It enlivens its child and clips through alignment.

3. Slide Transition
The slide transition permits you to change the ordinary place of the widget. It moves from right to left or left to right assuming one gives text direction.

Kinds of custom animation in Flutter:

There are by and large two methods for animating the widgets in Flutter, either tweens-based or physics-based.

  • > Tweens-based animation:
    Tween animation is the short name given “in-between”, and it produces pictures between two given keyframes. Keyframes are characterized as the pictures given at the initial and last mark of an animation — for example, the change of an animated creature hopping starting with one tree and then onto the next.

The tween animation gives in-between upsides of two alignments, positions, or tones. It naturally captures the progress going through a chain of middle-of-the-road values and adds the accuracy of characterizing the time and speed features.

  • > Physics-based animation:
    Physics-based animation gives a practical vibe to the spirits. The intelligent highlights of the application connect you to regular-world concepts and ideas.

You can animate the items by adding a spring, fall, glide, or swing characterizing the ideas of gravity. The animation deals with the contribution of movement entered by the client. The time, speed, and distance are determined by complying with the standard rules of physics.

How to animate a widget across screens in Flutter?

The animation, which shows a visual association when the client changes the components from one screen then onto the next, can be performed by animation in Flutter. This change is finished by utilizing a hero sort of movement.

Hero animations:

Hero routes are the least demanding to code in Flutter as it doesn’t need a lot of arrangement. The animation that shows smooth progress starting from one screen and then onto the next is Hero animation.

For instance, when you select a thing through a progression of thumbnails introduced in a sale, it takes you to another screen with a purchase option, and you can likewise fly back to the past screen. This sort of animation code is otherwise called a shared element transition.

The hero animation provides two types of animation codes:

  • Standard hero animation
  • Radial hero animation
  • > Standard hero animation: In standard animation code, the widget makes a trip starting with one space and then onto the next, finishing with a different shape and size than the first.
  • > Radial hero animation: Radial animation code has a shape change from circular to rectangular with progress starting with one screen and then onto the next.

Structure of Hero code animation: Two hero widgets are expected to carry out hero animation. The principal widget depicts the source course, and the subsequent one addresses the destination course.

Demo Module :

Constructor:

To utilize hero widget, you need to call the constructor underneath:

const Hero({
Key? key,
required this.tag,
this.createRectTween,
this.flightShuttleBuilder,
this.placeholderBuilder,
this.transitionOnUserGestures = false,
required this.child,
})

In Above Constructor all fields marked with @required must not be empty.

Properties:

There are some properties of Hero Widget:

  • child Widget: The widget subtree that will “fly” from one route to another during a Navigator push or pop transition.
  • createRectTween CreateRectTween: Defines how the destination hero’s bounds change as it flies from the starting route to the destination route.
  • flightShuttleBuilder HeroFlightShuttleBuilder: Optional override to supply a widget that’s shown during the hero’s flight.
  • placeholderBuilder HeroPlaceholderBuilder: Placeholder widget left in place as the Hero’s child once the flight takes off.
  • tag Object: The identifier for this particular hero. If the tag of this hero matches the tag of a hero on a PageRoute that we’re navigating to or from, then a hero animation will be triggered.
  • transitionOnUserGestures bool: Whether to perform the hero transition if the PageRoute transition was triggered by a user gesture, such as a back swipe on iOS.

How to implement code in dart file:

You need to implement it in your code respectively:

Create a new dart file called main.dart inside the lib folder.

We will create a stateless widget “FirstScreen” in which we will implement the Hero widget.

class FirstScreen extends StatelessWidget {
const FirstScreen({Key? key}) : super(key: key);

@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
automaticallyImplyLeading: false,
title: const Text('First Screen'),
),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Hero(
tag: "HeroOne",
child: Image.asset('assets/phone1.jpeg')
),
ElevatedButton(
child: const Text('Go to second screen'),
onPressed: () {
Navigator.push(context, CustomPageRoute(const SecondScreen()));
},
),
],
),
),
);
}
}

then we do the same for the second screen, and implement the Hero widget on that screen as well,

class SecondScreen extends StatelessWidget {
const SecondScreen({Key? key}) : super(key: key);

@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
automaticallyImplyLeading: false,
title: const Text("Second Screen"),
),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.start,
crossAxisAlignment: CrossAxisAlignment.center,
children: [
Hero(
tag: "HeroOne",
child: Image.asset('assets/phone2.jpeg')
),
ElevatedButton(
child: const Text('Back to first screen!'),
onPressed: () {
Navigator.pop(context);
},
),
],
)),
);
}
}

When we run the application, we ought to get the screen’s output like the underneath screen capture.

and lastly, for the page route animation, we will implement this code,

class CustomPageRoute<t> extends PageRoute<t> {
final Widget child;
CustomPageRoute(this.child);

@override
Color get barrierColor => Colors.black;

@override
String get barrierLabel => '';

@override
bool get maintainState => true;

@override
Duration get transitionDuration => const Duration(seconds: 2);

@override
Widget buildPage(
BuildContext context,
Animation<double> animation,
Animation secondaryAnimation,
) {
return FadeTransition(
opacity: animation,
child: child,
);
}
}

Code File:

import 'package:example_hero_widget_app/splash_screen.dart';
import 'package:flutter/material.dart';
void main() => runApp(const MyApp());

class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);

@override
Widget build(BuildContext context) {
return MaterialApp(
debugShowCheckedModeBanner: false,
routes: {
'/first': (context) => const FirstScreen(),
'/second': (context) => const SecondScreen(),
},
home: const Scaffold(
body: Splash(),
),
);
}
}

class FirstScreen extends StatelessWidget {
const FirstScreen({Key? key}) : super(key: key);

@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
automaticallyImplyLeading: false,
title: const Text('First Screen'),
),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Hero(
tag: "HeroOne",
child: Image.asset('assets/phone1.jpeg')
),
ElevatedButton(
child: const Text('Go to second screen'),
onPressed: () {
Navigator.push(context, CustomPageRoute(const SecondScreen()));
},
),
],
),
),
);
}
}

class SecondScreen extends StatelessWidget {
const SecondScreen({Key? key}) : super(key: key);

@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
automaticallyImplyLeading: false,
title: const Text("Second Screen"),
),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.start,
crossAxisAlignment: CrossAxisAlignment.center,
children: [
Hero(
tag: "HeroOne",
child: Image.asset('assets/phone2.jpeg')
),
ElevatedButton(
child: const Text('Back to first screen!'),
onPressed: () {
Navigator.pop(context);
},
),
],
)),
);
}
}

class CustomPageRoute<t> extends PageRoute<t> {
final Widget child;

CustomPageRoute(this.child);

@override
Color get barrierColor => Colors.black;

@override
String get barrierLabel => '';

@override
bool get maintainState => true;

@override
Duration get transitionDuration => const Duration(seconds: 2);

@override
Widget buildPage(
BuildContext context,
Animation<double> animation,
Animation secondaryAnimation,
) {
return FadeTransition(
opacity: animation,
child: child,
);
}
}

Conclusion:

In the article, I have explained the essential construction of the Hero widget in a flutter; you can alter this code as per your choice. This was a little introduction to the Hero widget on User Interaction from my side, and it’s working using Flutter.

I hope this blog will provide you with sufficient information on Trying up the Hero widget in your flutter projects. We showed you what the Hero widget is, its constructor, and its properties of the Hero widget. We made a demo program for the working Hero widget. So please try it.

Selenium WebDriver Architecture in Testing

Hi everyone! today we explore Selenium WebDriver Architecture In Testing. In the modern world, with each passing day, hundreds of web and mobile applications are being deployed to the web. QA team has to always be on their toes to ensure that these web applications are functional outside the development environment by ensuring the functionality is adequately tested before release to the customer.

Prior, this drawn-out task was finished by the manual testers through the human force of perception, taking a gigantic measure of time. Selenium entered the business. Selenium is a set-up of devices viz. Selenium IDE, WebDriver, Selenium RC, and so forth assist the QA with joining to mimic client activities on the internet browser and mechanizes the client stream, consequently helping in executing a huge no of experiments in a limited capacity to focus time.

Selenium Webdriver is one of the basic individuals from this family and is notable for its variety and security for web automation. Selenium Webdriver has sort of turned into a true for UI automation and over 80% of the organizations are utilizing it. Let’s understand the details of this tool by covering the following sections:

If you’re looking for the best Flutter app development company for your mobile application then feel free to contact us at — support@flutterdevs.com.

What is Selenium?

Selenium is a free (open source) automated testing framework used to validate web applications across different browsers and platforms. You can use multiple programming languages like Java, C#, Python, etc to create Selenium Test Scripts. Testing done using the Selenium testing tool is usually referred to as Selenium Testing.

Selenium Software is not just a single tool but a suite of software, each piece catering to different Selenium QA testing needs of an organization. Here is the list of tools

  • Selenium Integrated Development Environment (IDE)
  • Selenium Remote Control (RC)
  • WebDriver
  • Selenium Grid

At the moment, Selenium RC and WebDriver are merged into a single framework to form Selenium 2.

What is Selenium WebDriver?

Selenium WebDriver is a bunch of open-source APIs, which furnished the capacities to collaborate with any of the cutting-edge internet browsers and afterward, thus, computerize the client activities with that program.

It is a fundamental part of the Selenium family. As we probably are aware, Selenium is not a free device; rather, an assortment of instruments make the Selenium suite, which was made when two undertakings Selenium RC and WebDriver were blended.

Why use Selenium WebDriver for Web Automation?

Now that we know what Selenium WebDriver is and what it does let’s take a look at why it is the optimum choice to use for web automation.

  • DescriptionDynamic Web Page Automation: Selenium WebDriver can mechanize dynamic sites where the substance of pages changes by client activities.
  • Works Close to Browser: Program merchants transport their WebDriver execution. Subsequently, they are firmly coupled to the program giving a superior testing experience.
  • Technology Agnostic: Selenium WebDriver permits you to mechanize the experiments for all the web applications, regardless of the innovation utilized for the improvement of the application under test.
  • Mimics Real User: Selenium WebDriver permits QA to impersonate client activities on the sites. Selenium WebDriver can imitate ordinary client activities like structure filling, clicking, double tapping, and key-press, as well as cutting edge client activities like simplified, snap and hold, and so on.
  • Supports Cross Browser Testing: Selenium WebDriver enjoys the main benefit while doing cross-program testing — where a QA can test for a similar site, utilizing a similar piece of code on various programs. It empowers the confirmation and approval of experiments on numerous arrangements of programs simultaneously.
  • Supports parallel Execution: On the off chance that there are more scripts to be executed on numerous programs, doing them individually is tedious. So Selenium WebDriver permits equal execution, utilizing structures like TestNG, so the execution of experiments is quicker. This permits huge scope execution of experiments in a brief time frame.
  • View Execution Results: Selenium WebDriver permits a QA to see the live execution of the mechanized trial on the PC framework as well as on some other CI/CD pipeline machine by supporting functionalities like the screen capture, video-recording of test cases, and so on.
  • Supports modern development techniques: Selenium WebDriver coordinates very well with present-day Software Development standards like Behavior Driven Development through reconciliation with the Cucumber library.

In general, Selenium WebDriver is one of the main pieces of the Selenium suites, which upholds practically every one of the highlights required for the automation of a web application.

Why Selenium WebDriver is popular?

Apart from the above-mentioned capabilities, WebDriver, being part of the Selenium family, also encompassed some unique characteristics, which adds to its popularity as a web automation tool. A few of those characteristics are:

  • Multi-Browser Compatibility — One of the excellent explanations behind the prevalence of Selenium and WebDriver is its cross-program support utilizing a similar piece of code. It provides the capacity to run a particular piece of code that imitates a certifiable client utilizing a program’s local help to hit direct API calls without the requirement for any middleware software or device. The below shows a sample list of browsers supported:
  • Multi-Language Support — Not all testers are knowledgeable about a specific language. Since Selenium offers help for some dialects so a tester can utilize any language out of the upheld dialects and afterward use WebDriver for automation. This allows composing code in the language individuals is alright with.
  • Faster Execution —Unlike Selenium RC, WebDriver doesn’t rely upon a middleware server to communicate with the browser. WebDriver coordinates correspondences with browsers utilizing a characterized convention (JSON Wire), which empowers it to convey quicker than most Selenium devices. Additionally, since JSON Wire itself utilizes JSON, which is exceptionally lightweight, how much information move per call is extremely least. The below figure shows clearly how the WebDriver communicates with the Browser:
  • Locating Web Elements — To perform activities like Click, Type, Drag, and Drop we first need to distinguish on which web component (like button, checkbox, drop-down, text region) we want to play out an activity. To work with this, WebDriver has given techniques to distinguish web components utilizing different HTML credits — like id, name, class, CSS, label name, XPath, interface text, and so on.
  • Handling dynamic web elements — There are times when there are web components on the page that, change with each reload of the page. Since the HTML credits transform, it turns into a test to recognize these components. Selenium gives different strategies to deal with these circumstances –
  • Absolute Xpath — this contains the complete XML path of the element in question.
  • Contains( ) — using these functional elements can be searched with partial or full text and can be used to handle dynamic elements.
  • Starts-With( ) — this function is based on finding elements using starting text of the attribute under question.
  • Handling Waiting for Elements — Not every one of the pages has a similar construction. Some are lightweight, while some have a lot of information taking care of or AJAX calls. Commonly the web components get some margin to stack. To represent this WebDriver has given various holding up components that can be utilized to stop the content execution for a necessary measure of time given specific circumstances and afterward proceed with once the condition is full-filled. The accompanying figure shows an example list that shows the capacities of WebDriver which helps in dealing with the unique way of behaving of web pages.

What are the drawbacks of Selenium WebDriver?

Although Selenium works a long way out in solving the *UI *and functional automation of web applications, it is not without its drawbacks. Let’s look at some of the shortcomings/drawbacks:

  • Requires Programming Knowledge and Expertise — Since WebDriver permits you to computerize the client activities utilizing code written in a specific programming language, any individual who needs to utilize it ought to have an essential comprehension of how coding in the language functions. Individuals who don’t have a comprehension of coding in a programming language will find it hard to utilize WebDriver.
  • No Support for Desktop Applications — Selenium environment, including WebDriver, was worked for the automation of web applications. In that capacity assuming you are hoping to Automate windows based applications, you can not do such.
  • No Customer Support — The selenium ecosystem, including WebDriver is open-source, and that implies it is driven by people and not by any organization. Along these lines, there is not a committed help group to investigate your issues. On the off chance that an individual has stuck someplace, there are numerous networks, and discussions on which an individual can depend, however, there’s nothing else to it.
  • No Built-In Object Repository — Paid tools like UFT/QTP give a concentrated area to store objects/components, called the Object Repository. This capacity isn’t given as a matter of course in Selenium WebDriver. This can be defeated utilizing approaches like the Page Object Model, yet it requires impressive coding abilities and aptitude.
  • Lack of built-in reporting — Selenium WebDriver can assist you with running your automation tests yet to give a detailing capacity, you would have to coordinate it with a testing framework like Junit, TestNG, PyTest, Allure, and so on.
  • Managing Browser-Selenium Dependencies —Since Selenium needs to depend on similarity between the program drivers and the genuine program itself, commonly because of contradiction or bugs in either the program driver or program, usefulness breaks, and clients need to depend on local area backing to sort it out.

Understanding of Selenium WebDriver Architecture:

Being a piece of the general part framework, we find that the Selenium WebDriver isn’t a standalone testing tool. It involves different parts that are expected to run tests. These are the architectural components of Selenium.

So first let’s take a look at this image below

This image tells us about the core selenium web driver architecture and the major selenium components which comprise WebDriver.

  • Selenium WebDriver Client Libraries / Language Bindings — Software Testers need to select languages that they are comfortable with. Since WebDriver Architecture upholds various dialects, so there are ties accessible for a scope of dialects like Java, C#, Python, Ruby, PHP, and so on. Any individual who has fundamental information on working with any programming language can get explicit language ties and can get going. This is the way Selenium Architecture gives adaptability to testers to do automation in their usual range of familiarity.
  • JSON WIRE PROTOCOL — According to the Selenium Architecture over, the JSON Wire Protocol works with all the correspondence that is occurring in Selenium between the program and the code. This is the core of Selenium. JSON Wire Protocol gives a medium to information move utilizing a RESTful (Representational State Transfer) API which gives a vehicle system and characterizes a RESTful web service using JSON over HTTP.
  • Browser Drivers — Since different programs are upheld by Selenium, every program has its execution of the W3C standard that Selenium gives. As such program explicit doubles are accessible that are intended for the program and conceal the execution rationale from the end client. JSONWire convention lays out an association between the program pairs and the client libraries.
  • Browsers — Selenium will be simply ready to run tests on the browser if they are privately introduced, either on the local machine or on the server machines. So browser installation is essential.

How does Selenium WebDriver work?

In the section above, we saw the architecture of Selenium. Now let’s see how behind the scenes all the communication happens.

Take a look at the image below — this shows a view of what the actual workflow looks like.

When a user writes a WebDriver code in Selenium and executes it, the following actions happen in the background:

  • An HTTP request generates, and it goes to the respective browser driver (Chrome, IE, Firefox). There is an individual request for each Selenium command.
  • The browser driver receives the request through an HTTP server.
  • The HTTP server decides which actions/instructions need to execute on the browser.
  • The browser executes the instructions/steps as decided above.
  • The HTTP server then receives the execution status and then sends back the status to an automation script, which then shows the result ( as passed or an exception or error).

How to use Selenium WebDriver for Web Automation?

Selenium WebDriver provides a very seamless, user-friendly, and code-friendly approach to automation using various browsers. Since it supports most of the major browser vendors, it’s just a matter of using the respective browser driver and browser and setting up Selenium to use the same.

For any Selenium test script, there are generally the following 7 steps, which apply to all the test cases and all the applications under test (AUT):

  1. Create an instance of WebDriver specific to the Browser:
  • Eg: To create an instance of the Firefox driver, we can use the following commands:
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
WebDriver driver = new FirefoxDriver();

2. Navigate to the desired Web page which needs to be automated:

driver.get("https://www.google.com/")

3. Locate an HTML element on the Web page:

  • To interact with a web page, we need to locate the HTML elements on the web page. We can use any of the element locator strategies mentioned in “Selenium Locators”. Eg: if we want to get the “Full Name” text box, we can use the following commands:
import org.openqa.selenium.By; 
import org.openqa.selenium.WebElement; 
WebElement usernameElement = driver.findElement(By.id("userName"));

4. Act on an HTML element:

We can perform certain actions on the HTML elements, such as typing something using the SendKeys method, and clicking on the element if it is a button. Eg: if we want to type the name in the identified text box, we can use the following commands:

usernameElement.sendKeys("Pragati Oli");

5. Run tests and record test results using a test framework.

And, we are done with using the WebDriver to identify and perform the needed actions on the Web Application. Depending on the browser, on which we need to test our application, we can use the corresponding WebDriver.

Here is a list of various browsers and their respective browser drivers:

Recently Microsoft moved their Edge browser to the same platform as Chromium (which is the parent for Chrome), and due to this ChromeDriver can now also support Microsoft Edge Chromium.

Conclusion:

Selenium is a cost-effective and flexible tool developer can use in the automation testing of their web applications. The most intriguing feature of this software is the capacity to test applications across different internet browsers. This guarantees that sites don’t crash or breakdown down specific programs.

The Selenium software is great for organizations creating applications that help heavy traffic, particularly friendly stages and internet business sites. This software has gone through progress throughout the long term, which has increased the value of web development.

Explore Freezed In Flutter

Hello Everyone.! In this article, we learn about Freezed in Flutter Application. And how it works in Flutter Applications. With the help of freezed, we can reduce the lines of code.

If you’re looking for the best Flutter app development company for your mobile application then feel free to contact us at — support@flutterdevs.com.

Conclusion

Introduction:

Freezed is a code-generation package that helps you to create data classes in Dart. It stops you from writing a ton of error-prone lines. Sometimes you just want a class that obtains its values in a constructor, a toString method, and maybe value impartiality. That lone is a lot. But now visualize you want objects to remain fixed. For that, you need an extra copyWith method. If you know how to implement all this in Dart, you surely know that it takes many lines of code to achieve this.

How to Use Freezed:

  • Project Setup:- For using freezed first you need to create a project. Open Android Studio, create a new Flutter Project, and add the project’s name, project location, description, and also domain. For any project, we have to choose the platform, on which we want to run our project. After that, we have to add some dependencies which are necessary to use
  • Install:- First we have to add some dependencies in our project by which we can easily use Freezed. Build_Runner, Freezed, Freezed_Annotation.
dev_dependencies:
flutter_test:
sdk: flutter
build_runner: ^2.1.7
freezed: ^1.1.1
freezed_annotation: ^1.1.0

or we can add these dependencies by using commands.

flutter pub add freezed_annotation
flutter pub add --dev build_runner
flutter pub add --dev freezed

> freezed:- Freezed package is used to create the model. It’s code generator for data-classes/unions/pattern-matching/cloning.

> build_runner:- The build_runner package provides a concrete way of generating files using Dart code, outside of tools like the pub. Unlike pub serve/build, files are always generated directly on disk, and rebuilds are incremental – inspired by tools such as Bazel.

> freezed_annotation:- Freezed_annotations for freezed. This package does nothing without freezed. If we want to use Freezed so we have to use this package without this we can’t use Freezed.

  • Run the generator:- To run the code generator, execute the following command.
flutter pub run build_runner build

> When the packages providing Builder are configured with a build. ymal file they are designed to be consumed using a generated build script. Most builders should need little or no configuration, see the documentation provided with the Builder to decide whether the build needs to be customized. If it does you may also provide a build. ymal with the configuration.

and also add import the packages in dart file.

import 'package:freezed/builder.dart';
  • Creating a Model using Freezed:- First, you have to create a class that has the @freezed annotation. We create a class with the name of TestModel{}.
import 'package:freezed_annotation/freezed_annotation.dart';part 'response.freezed.dart';
part 'response.g.dart';@freezed
class TestModel{}

After creating the class we define the class with mixins. A mixin is a class whose methods and properties can be used by other classes without sub-classing.

import 'package:freezed_annotation/freezed_annotation.dart';part 'response.freezed.dart';
part 'response.g.dart';@freezed
class TestModel with _$TestModel{}

Now we add a factory method as a constructor with a list of all the arguments/properties. Here we have defined @Default inside the factory method which comes from ‘freezed_annotation’.The @Default annotation is used to set a default value for non-required properties.

import 'package:freezed_annotation/freezed_annotation.dart';part 'response.freezed.dart';
part 'response.g.dart';@freezed
class TestModel with _$TestModel {
@JsonSerializable(fieldRename: FieldRename.snake, explicitToJson: true)
const factory TestModel({
@JsonKey(name: 'id') int? id,
@JsonKey(name: 'label') String? label,
@JsonKey(name: 'image') String? image,
@JsonKey(name: 'status') int? status,

}) = _TestModel;

And at last, we have now created our constructor, In which we have to implement fromJson/toJson. In the freezed package, fromJson and toJson are not generated, but it knows what json_serializable is.

import 'package:freezed_annotation/freezed_annotation.dart';

part 'response.freezed.dart';
part 'response.g.dart';@freezed
class TestModel with _$TestModel {
@JsonSerializable(fieldRename: FieldRename.snake, explicitToJson: true)
const factory TestModel({
@JsonKey(name: 'id') int? id,
@JsonKey(name: 'label') String? label,
@JsonKey(name: 'image') String? image,
@JsonKey(name: 'status') int? status,

}) = _TestModel;

factory TestModel.fromJson(Map<String, dynamic> json) =>
_$TestModelFromJson(json);
}

For creating a response.freezed.dart and response.g.dart we have to run the command if we don’t run this command so our code will show errors. The next step is to navigate within the terminal to the folder where our project is located and execute the following command.

flutter pub run build_runner build --delete-conflicting-outputs

Conclusion:

In this article, we have been through how to use Freezed in Flutter. In this, you can see how it is to use, how much code will be saved, and also the time we can save by using freezed By using we can perform many operations and create a Flutter application.
