The animation is the word that always fills joy in users as well as in developers when it comes to experiencing better user-friendly UI designs. here in Flutter, there are some inbuilt animations provided by flutter but when we need to show something better than this and then we use Flare.
So here I am going to give a little introduction of Flare, Flare is basically used for animations and it helps to get a better UI experience to the user.
for Flare we use 2Dimensions and here you have to create your account if you have not created it before then you start working on it.
In this tool, there are two options Design and Animate, in design first you choose design patterns or images and then you animate all these things, you can also import images like png and SVG according to your choice, in design part, there are many options here you can choose shapes of designs, can rotate, can set scale can also add other features,
while you are designing the basic layout you mainly focus on the position of components and when you want to move your components at different position you have to fill that x and y value with clicking that box beside it and you will observe it is moving with its respective position,
after this we come in animation section here by clicking on each component which you added in a design you can move it according to your choice by giving positions in X-axis and Y-axis when you enter the position of a particular component and click on the box next to it, it automatically moves into the next place.
you can observe it in a video added below where every component is taking place of the component next to it.
This was the basic overview of the tool and we have to move in the next section where we would add it in our App.
How to use flare in Flutter:
As we know that flutter does not have the support of flare so we can implement it by using a plugin.
Implementation:
Step 1: Add the dependencies
Add dependencies to pubspec.yaml file.
Dependencies:
flare_flutter: any
after adding this dependency you have to add your flare file in assets
assets: - assets/flutter_flare_new.flr
How to implement in dart file:
Now after adding dependency and asset, you need to implement it in your code respectively
In the above code library of flare has been imported and here a widget FlareFactor has been used to implement the flare. and it is wrapped with Inkwell that makes it interactive when you tap on it, it starts again.
here in the video posted below, you will see how fonts are moving around a button and when you tap anywhere in that circle it starts again, but flutter also provides the functionality by which you can allocate a specific area for tap. It means in different parts of animation you can perform different actions.
So this was the basic introduction of Flare where we did a simple example and you can learn at least how it can be started?

Hello Everyone, This article is inlined for those who are keen to start with flutter, A roadmap for beginners to learn gradually from all the necessary resources.
What is Flutter?
Flutter is Google’s UI toolkit for building beautiful, natively compiled applications for mobile, web, and desktop from a single codebase.
Introductory to flutter is in best summarised in below-mentioned videos;
Why Flutter??
We already know there are a lot of frameworks out there that provide the cross-platform functionality then what makes flutter standalone in this rat race?
Fast Development
Flutter’s hot reload helps you quickly and easily experiment, build UIs, add features, and fix bugs faster. Experience sub-second reload times, without losing state, on emulators, simulators, and hardware for iOS and Android. Learn more
Expressive, beautiful UIs
Delight your users with Flutter’s built-in beautiful Material Design and Cupertino (iOS-flavor) widgets, rich motion APIs, smooth natural scrolling, and platform awareness. Browse the widget catalog
Native Performance
Flutter’s widgets incorporate all critical platform differences such as scrolling, navigation, icons and fonts to provide full native performance on both iOS and Android. Examples of apps built with Flutter
Check out what Flutter is capable of
Here are the showcases of flutter apps that developers around the world have built.
Flutter is fast and easy, If you are familiar with java or any object-oriented language you are good to go but I strongly recommend that you should have the basic knowledge of Dart.
These are some videos that you might find helpful to watch.
or you can use the IDE (Intellij, Android Studio, etc)
Project overview
When you create the flutter app you will see these files and folders, Most of the code is written in dart in lib folder and when In case of the native requirement android and ios are required.
Have got excited when you first app launches (Technically it’s not yours, Code was already there 😜 ). I got excited too 🎉.
When you create your flutter app you will see there is already code for a counter app.
When you run the code, you will see this. This is a simple counter application where you have a FAB(FloatingActionButton) and Text which indicate how many times the FAB has been pressed.
Widgets in flutter
If you see the code you will see StatefulWidget and StatelessWidget. Before we dive into that let’s understand what is a Widget in a flutter.
There’s also a youtube playlist (Widget of the week )provided by the Flutter team that only talks about Widgets in flutter.
Now
What is a Stateful and Stateless Widget?
In Stateless Widget, all of its properties are immutable which means a StatelessWidget will never rebuild by itself (but can from external events) but a StatefulWidget can.

Google has created quite a buzz with the roll-out of synchronous updates in Flutter 1.9 & Dart 2.5, it’s developer tool for building Cross-platform apps at Chinese Developer Conferencein late ’19 attracting developers around the globe to adapt flutter . Flutter’s newest version allows developers to write for mobile, desktop and web with the single codebase..
Flutter 1.9 & Dart 2.5 has come up with a lot of advancements from their previous version updates to strengthen their app development process and Apparently, The reason why flutter is creating quite a Stir Nowadays.The Major revelation though from all being the Successful Integration of the Flutter Web Support to the main Flutter Repository and Ml integration.
Still Unaware of the Recent Updates , Let’s Go!
Quick Keynotes of Update :
Flutter 1.9 Version will allow mobile app development companies to create mobile, web and desktop apps from Single Codebase.
Flutter 1.9 include support for iOS 13 and macOS Catalina.
Google Updated the Dart Language by integration of ML Autocomplete.
What’s New in Dart 2.5 : Supercharged development?
Flutter web
Dart has been updated to version 2.5,the Dart SDK brings a technical preview of ML Complete, Google’s take on machine learning-powered automatic code completion. It also includes the ‘Foreign Function Interface’ for calling C code directly from Dart which provides machine learning-powered code completions for the IDE.
New language defaults: New projects default to Swift instead of Objective-C and Kotlin instead of Java for iOS and Android projects respectively.
Default Language: Swift => Objective C Java => Kotlin
Suppport for Flutter Web: Upgrade your Flutter from the master or dev channel, so that you can target the web with the latest experimental version of Flutter .Support for web output with Flutter is still at an alpha phase, but this release represents a major step forward towards enabling Production support forweb development with Flutter. It include a flag to tell if an app is running on web (KIsWeb) right now .To view commonly asked questions and answers, see the web FAQ.
Building a web application with Flutter
To add support to an existing flutter project , run the following commands in the terminal of your project package:
Download the Flutter SDK:
Currently, you need either the master or dev channel of the Flutter SDK for web support. If you have the flutter tool installed already , run the following commands to install latest version :
$ flutter channel dev $ flutter upgrade
The flutter upgrade command fails when “origin” points to a personal fork. To nulify that enter the following:
cd <inside local copy of the flutter/flutter repo> git remote get-url origin ssh://git@github.com/flutter/flutter.git
Use the config command to enable web support:
flutter config --enable-web
Once web is enabled, flutter devices outputs a device named Chrome.
flutter devices 1 connected device:
Chrome • chrome • web-javascript • Google Chrome 76.0.3809.100
After enabling web support, restart the IDE. You Should now see Chrome (web) in the device pulldown to ensure correct installation.
NOTE : Support for web output with Flutter is still at an alpha phase. Not recommended for production yet but you can always Try out!
Also, What’s New in Flutter 1.9 Version?
Integrated Web Support with Main Repository of Flutter: With the latest version of Flutter 1.9, developers can have a Unified repository which makes it possible to develop applications for Mobile, Desktop and Web using the Single Codebase.
Now when web developers Create a project, the framework would create a web runner using a minimal web/index.html file that bootstraps the web-compiled code and accomplish web development processing.
The file would enable using either the Flutter CLI tool or IDE plugins so developers can edit and run flutter applications on the web. It’s built into the dart analyzer availed across dart-enabled editors, including Android Studio, IntelliJ, and VS Code.
For those keen to try Dart ML Complete, Google is recommending using the Flutter dev channel or the Dart dev channel.
Support Of New Material Widgets: Flutter 1.9 brings you up a wide range of Features and Material components that can make your web app development process far easier and hassle-free aiming to pixel- perfect User-experience .
Toggle Options: It offer a row of buttons and icons and have them as Single-selection or Multi-select options, as well as to require at least one selection also permitting none to be selected.
Worldwide Multi-Language Support: Flutter now suppports 24 additional languages including :
Structured Error messages : Error message are now made much more developer friendly , credits to flutter team working exponentially diligently to make them more Concise , Understandable and Actionable.
Added Support for iOS 13 And macOS Catalina:Google wants to make sure that Flutter is all ready to support the latest version of macOS. Flutter 1.9 added support for new Xcode build systems, enabling 64-bit support throughout the toolchain and simplifies the platform dependencies.
Note: Before upgrading to Catalina, you’ll need to upgrade to the Flutter 1.9.1 stable release the other order works, but you’ll see an error when you do it that way.
Flavors introduction: flavors are introduced in flutter also now for all to define some build configuration and switch them if you want : Staging, Development, Release.
Flutter build aar: new build command work exactly the same purposely as ‘flutter build apk’ or ‘flutter app bundle ’ but for plugins .
Advancement in Toolchain: With the latest release of Flutter 1.9, new projects default to Swift instead of Objective-C and Kotlin instead of java .
For more details on upgrading to Flutter 1.9, including details on how to fix any breaking changes that you might experience as you migrate your code, check out the detailed Flutter 1.9 release notes.
Closing Thoughts
This year has been Quite Eventful for flutter and Dart enthusiasts as this has paved up paths for many to adapt early to this wondrous Framework.
Hopefully, this blog will help you in trying out the Advancements in flutter & Flutter for web early adding a Perfect competitive niche to your business from your Peers.

Hello Everyone, This article is about how to paginate your data from the Firebase firestore.
What is Pagination?
“Pagination, also known as paging, is the process of dividing a document into discrete pages” When we gradually load the chunks of data and display it. It’s efficient, quick, and server-friendly to split the results up into multiple data set . if we fetch all the data at one time then things start slowing down the more results which are returned.
What do we want?
We are fetching the data from the firestore in chunks and display it our app.
Fetch data from firestore
We need to fetch all the documents from the movies collection, if we fetch all the data at once, it will be very hard to handle so we need to fetch the data gradually.
we will check every time a list reaches at the end and then we fetch the next list.
void _scrollListener() { if (controller.offset >= controller.position.maxScrollExtent && !controller.position.outOfRange) { print("at the end of list"); movieListBloc.fetchNextMovies(); } }
Let’s define the fetchNextMovies() in our MovieBloc.
when we fetch the next list, we are appending the documents in the existing list and sink the documents in3 the stream and update the UI using StreamBuilder .
To get the more idea, have a look at more way to paginate your data

Hello folks!, If you are a Flutter Developer you could have better or bitter experience while developing apps that require you to manage states as well. In flutter, there are various techniques for state management some of them are:
setState()
Inherited widget & Inherited Model
Provider & Scoped Model
Redux
BloC/Rx
MobX
Flutter_BLoc
As a flutter developer, I have experienced that all techniques are best but all have their benefits while flutter_bloc contains important and valuable things from other state management techniques mentioned above.
Why Bloc?
When we are building production quality application state management becomes a critical issue and being a developer we only want to know a few things and these are
How states are changing.
How an application is making interaction that actually helps to make data-driven decisions.
Is the developer able to work with a single code base following the same pattern?
fast and reactive apps.
and it is designed with three core values in mind and these are simplicity, powerfulness, and testability.
Before working with it we need to understand what its inner widgets do and how we manage our data with, Now firstly we have to get the basic knowledge of flutter_bloc.
Basic design patterns are used to make the project well managed, responsible, scalable, and optimized so the flutter_bloc does.
Implementation:
Step 1: Add the dependencies
Add dependencies to pubspec.yaml file.
dependencies:
flutter_bloc: ^latest version
Step 2: Import
import ‘package:flutter_bloc/flutter_bloc.dart’;
this is the installation flutter_bloc now let’s move to understand
core conceptsof the bloc.
There are various core concepts of the bloc to understand its working,
Events
Events are the inputs of the bloc and it is generally done by making an interaction by the user
Interaction, while designing an app is the basic task and in the upcoming example, we will better know how to fire an event during an interaction.
Generally, we fire an event when we make any interaction when we call onTap but here in the example, we will be making an API call without any button interaction so the event will be fired when we will be instantiating it in main.dart
States are the output of the bloc, it notifies the UI component of the app and helps it to rebuild itself according to the state.
As we have defined event in the app and it is for fetching data from API, then it will be mapped into the state by bloc and UI will be redrawing itself according to it.
class UserDetailsLoadedState extends UserDetailsState { UserResponseModel userResponseList; UserDetailsLoadedState(this.userResponseList); }
Transition
Transition helps to find out changes from one state to another, It holds the current state and the event and the next state
Basically, it helps to observe when and where states are getting changed It depends on the developer if he/she wants to use it or not.
Now after a small introduction let’s move to the core concept of Flutter Bloc
Bloc
Bloc (Business Logic Component) converts the incoming stream of events into outgoing stream of states
Every bloc converts every event into the state, and it can be accessed by using state property
Bloc Builder is a flutter widget that requires bloc and builder functions and it manages the widget according to new states
BlocBuilder<BlocA, BlocAState>( builder: (context, state) { // return widget here based on BlocA's state } )
BlocBuilder also contains few properties like bloc and condition for a specific purpose like when you want to specify a particular bloc and previous bloc. You can find a brief description here.
BlocProvider:
It is used as a dependency injection so that it can provide bloc to its children, there are different types to implement it but it depends on no. of blocs are implemented in any app, for single bloc you use BlocProvider.of<T>(context) but if you are managing your app by multiple blocs the MultiBlocProvider will be used to implement it
Now let’s implement it, for the sake of simplicity first create a package in the lib and make different classes for the event, state and bloc,
after this first, we make an event in the event class that will be fired when the application will start for fetching data.
abstract class UserDetailsEvent { const UserDetailsEvent(); }
class FetchUserDetailsEvent extends UserDetailsEvent { FetchUserDetailsEvent(); }
then we make all possible states which could happen in state class, state class must contain initial state because it is the state before any event has been received.
class UserDetailsState {}
class UserDetailsInitialState extends UserDetailsState {}
class UserDetailsLoading extends UserDetailsState {}
class UserDetailsLoadedState extends UserDetailsState { UserResponseModel userResponseList; UserDetailsLoadedState(this.userResponseList); }
class UserDetailsError extends UserDetailsState { Error e; UserDetailsError(this.e); }
there could be four possible states like
initial state,
loading state: when data is loading,
loaded state: when data is loaded,
error state: if we found any error.
Now let’s move to the bloc, here bloc mapEventToState means which event is fired will be converted in to map, in this code snippet we have called that event which we have fired from event class and all four possible states are used.
class UserDetailsBloc extends Bloc<UserDetailsEvent, UserDetailsState> { UserRepository userRepository = UserRepository();
@override UserDetailsState get initialState { return UserDetailsInitialState(); }
now let’s understand how we call API using retrofit, for this, we have to add few dependencies retrofit, json_serializable,build_runner, and retrofit_generator
then we define and generate API and for this, you should have at least JSON parameters and then you to define it as mentioned below
here one thing is very important which is @JsonKey(name: “ ”) becuase if JSON response is containing key like “per_page”
then during the parsing, it would give an error, so you need to define it by @JsonKey(name: “per_page”) above the particular key.
then we write the factory method as it is, now it may contain few errors but leave it for now, we will handle it a few steps later
we implement HTTP methods and add parameters required
after this, we import
part 'class_name.g.dart';
in JSON model class(you can see above model class) run a command in the terminal,
flutter pub run build_runner build
here you will observe those errors have gone because all the required methods have been generated automatically and if you make any changes in it then you have to run the next command in the terminal,
flutter pub run build_runner build --delete-conflicting-outputs
the auto-generated files will be refactored.
after we call this API in bloc class and we fetch all the details using state in Our UI

Images are major to each application. They can give urgent data by filling in as visual guides or just working on the stylish of your application. There are numerous ways of adding an image to your Flutter application.
At the point when you make an application in Flutter, it incorporates both code and resources (assets). An asset is a document, which is packaged and sent with the application and is open at runtime. Showing pictures is the major idea of most versatile applications.
This blog will explorethe Rendering Image From Byte Buffer/Int8List In Flutter. We will see how to implement a demo program. We are going to learn about how we can render an image in your flutter applications.
Perusing byte data from a given URL of an image and you can change this move to suit what is happening, like getting byte data from a file or a database Utilizing Image. memory to render the image from byte data.
Demo Module :
The above demo video shows how to render an image in a flutter. It shows how rendering an image from a byte will work in your flutter applications. It shows an image with its URL instead of the detour of getting its bytes from the URL and then using this byte list to display the image. It will be shown on your device.
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.
In Flutter, you can render a picture from an Int8List of bytes by utilizing the Image. memory constructor like:
Image.memory(Uint8List.fromList(myBytes));
Assuming that what you have are byte buffers, utilize this:
In the main. dart file, we will create a HomeScreen class. In this class, first, we will add Int8List byte data that will be used to render the image.
Int8List? _bytes;
Now, we will create a _getBytes() method. In this method, we will get byte data from an image URL. Inside, we will add the final ByteData data is equal to the NetworkAssetBundle(). We will add _bytes is equal to the data.buffer.asInt8List().
void _getBytes(imageUrl) async { final ByteData data = await NetworkAssetBundle(Uri.parse(imageUrl)).load(imageUrl); setState(() { _bytes = data.buffer.asInt8List(); print(_bytes); }); }
Now, we will create an initState() method. In this method, we will add _getBytes(Your Url’).
@override void initState() { // call the _getBytes() function _getBytes( 'https://upwork-usw2-prod-assets-static.s3.us-west-2.amazonaws.com/org-logo/425220847461273600'); super.initState(); }
In the body, we will add the Center widget. In this widget, we will add _bytes is equal-equal to null then, show CircularProgressIndicator. Else, show an Image.memory(). Inside this function, we will add Uint8List.fromList(_bytes!), width, height, and fit is equal to BoxFit.contain.
In the article, I have explained the Rendering Image From Byte Buffer/Int8List basic structure in a flutter; you can modify this code according to your choice. This was a small introduction to Rendering Image From Byte Buffer/Int8List On User Interaction from my side, and it’s working using Flutter.
I hope this blog will provide you with sufficient information on Trying upthe Rendering Image From Byte Buffer/Int8List in your flutter projects. We will show you what the Introduction is. Make a demo program for working with rendering an image from Int8List in your flutter applications. So please try it.

Hi everyone, In this article, we will be learning how to implement the dark theme in our app using the provider package
As we all now Dark theme is trending and most of the popular app has the feature to turn into the dark mode.
There are two ways to turn on the dark mode in any app:
1: Adding a custom option to change to the dark mode (Eg: Twitter, Medium app)
2: Depends on the Phone system setting (Eg: Instagram)
We already have both the options in flutter.
If you check the MaterialApp widget you will see
We have the theme and darkTheme parameter in MaterialApp widget we can provide the dark ThemeData in darkTheme and light ThemeData in theme if we want our app to change the theme according to the system preferences.
And if we have a custom button or something to change the dark theme then we just have to put some condition to change it.
we are using the SharedPreferences to set the value in the memory so even if we close the app and reopens it, our data won’t lose. Provider is used to manage the state when the dark theme is implemented on the app.
We are creating a separate class for the SharedPreferences so the code won’t mess up.
We have created a class DarkThemePreference where we are storing the bool value in for the dark theme, we have two methods for saving and retrieving the bool value.
We are accessing the preference value through the provider so whenever there is any change the notifyListeners() UI will be updated if we have attached the provider to the screen.
Step 4: Add custom theme data for dark mode
if you see we have to provide the ThemeData , so I have created a method for dark and light mode.
If you see the getCurrentAppTheme method, I am fetching the value from the preferences and set the value in the provider.
Now we will add notifier to the material app which is ChangeNotifierProvider and set a provider model to it, if any change happens in the provider it will notify its descendants.

As we all know Flutter has come up with new announcements in Flutter Interact which was recently held on Dec 11, 2019. Generally, developers eagerly wait for new announcements that Google Flutter is going to make and then observe and work with them, this time also Google Flutter wanted to make it a big release and for that, they prepared for it. In this release according to flutter they have merged 1905 pull requests from 188 contributors including Google and non-Google contributors.
Since its first release from Flutter 1.0 to Flutter 1.12, it’s 5 stable versions have been released and the flutter team always improved its shortcomings and in Flutter 1.12 they have come up with few new concepts and were focused on the concept of Ambient Computing.
Before we review announcements of Flutter 1.12 let’s take the overview of Ambient Computing.
Ambient Computing: When developers start developing an app they always find themselves in the dilemma that which gadget they need to aim while they are developing an app.
Actually, the fact is we daily use different internet-connected devices with the same purposes so the Flutter development team has decided to create a milieu that makes users use all services across all the devices now they have come with the concept of “ Write Once, Read Everywhere” and this is the ambient computing.
In all the flamboyant announcements this is the most awaited release because it is addressing one important problem which will help to handle and prevent errors when variable get a zero value and parse an integer. This string handling ability makes it the richest among all.
Beta web Support
Flutter for Web has been an astonishing release among the developer community and now the Flutter development team has added another feather in the cap by shifting it into beta version and by making it easier to apply Dart Compiler and Flutter architecture efficiently.
macOS Desktop Support
In this segment, developers will able to use release mode to develop a fully optimized macOS application with the help of Flutter
Desktop app support got rich with various new updates like menu dropdown keyboard navigation, visual density assistance, checkboxes, radio buttons and many more.
Linux and Windows support is also in the up-gradation Stage and soon will be upgraded.
iOS 13 Dark Mode
Flutter 1.12 also described the addition of complete dark mode in iOS13, previously flutter also provided support for auto toggling to dark mode on Android 10, all the iOS-like widgets, named Cupertino are available in dark mode. they can automatically be enabled by turning the dark mode on.
Another Feature of Flutter 1.12 is it makes developers enable to add flutter in the current Android and iOS app, Migration of an app in flutter is possible once, instead of creating it from the beginning.
Here in this video of Flutter dev, you can get an idea of doing it easily.
In updated DartPad not only the entire code can be edited but also can be assessed the rendered UI and running the flutter code efficiently.
Adobe XD to Flutter Plugin
Now flutter has come up with a new collaboration with Adobe XD and XD is accessible for flutter plugins. Actually flutter is trying hard to make developers work easy and this is the kind of effort where the latest XD in Flutter changes the XD designs automatically into code and makes it usable part of flutter development.
New Google Fonts Package
Flutter added this improvement in order to beautify user experience by adding 1000s open-source font families.
It helps to designers to add different typography while developing within a few code lines.
Multi-device Debugging
As a developer, we always develop and debug our flutter UI and when we want to debug it on different devices we need to debug it separately for the individual device but now flutter has come with the solution for this by adding multi-device debugging.
These were the important new features every developer should go with.
What is really needed to make it more efficient and compete with others
Flutter is trying hard to take the lead over the debate on Flutter Vs React native and this is a gamechanger effort that is surely going to get a lead. After all these announcements if we are still missing something which is pushing of codes of the designed apps directly.
Hope Flutter team will surely work on it and in upcoming announcements, we might see some new features in all segments.
Thanks for reading this article, if you find something you better know Please let me know, I will welcome it with full gratitude.

For AppBar , I have created a separate widget method because you must have seen in apps when selecting it’s the app bar changes. We also need to update the app bar whenever we are selecting items.
We will check in the selectedList length whether it has any item in the list and change the app bar accordingly.
