Hello friends, I will talk about my new blog on Feature Discovery In Flutter. we will explore the Feature Discovery In flutter using the feature_discovery_package. With the help of the package, we can easily achieve the flutter feature discovery. So let’s get started.
feature_discovery | Flutter Package
This Flutter package implements Feature Discovery following the Material Design guidelines. With Feature Discovery, you…pub.dev
Table of Contents :
Flutter :
“ Flutter is Google’s UI toolkit that helps you build beautiful and natively combined applications for mobile, web, and desktop in a single codebase in record time, Flutter offers great developer tools, with amazing hot reload”
Feature Discovery :
The Feature Discovery Package animated implements feature discovery following custom design guidelines, in this, we can use any widget within feature discovery, we use it to introduce the user to a feature about which they wouldn’t you know.
Demo Module :
Implementation :
Step 1: Add the dependencies
Add dependencies to pubspec — yaml file.
dependencies :
dependencies:
feature_discovery: ^0.13.0+2
Step 2: Importing
import 'package:feature_discovery/feature_discovery.dart';
Step 3: Run flutter package get
Code Implementation :
Create a new dart file called flutter__zoom_drawer_demo.dart inside the libfolder.
First of all, we have to wrap our widget tree in the feature discovery widget and inside it, we will add any class or material to the child widget.
FeatureDiscovery(
recordStepsInSharedPreferences: false,
child: FeatureDiscoveryDemoApp(),
),
Now we will implement FeatureDiscovery.discoverFeature inside the initState() method in which we will give the feature’s id so that the user taps the first feature then it will be sent to the next feature.
@override
void initState() {
WidgetsBinding.instance.addPostFrameCallback((timeStamp) {
FeatureDiscovery.discoverFeatures(context,
<String>[
'feature1',
'feature2',
'feature3',
'feature4',
]
);
});
super.initState();
}
Now we will discuss DescribedFeatureOverlay () widget. This widget takes all the parameters for an overlay displayed during feature search that will display the overlay as its child. This will pass a feature ID inside it which is of string type using the ID. So that we can know which feature is shown on this screen, we have defined feature1, first of all, we will see this feature.
DescribedFeatureOverlay(
featureId: 'feature1',
targetColor: Colors.white,
textColor: Colors.black,
backgroundColor: Colors.red.shade100,
contentLocation: ContentLocation.trivial,
title: Text(
'This is Button',
style: TextStyle(fontSize: 20.0),
),
pulseDuration: Duration(seconds: 1),
enablePulsingAnimation: true,
overflowMode: OverflowMode.extendBackground,
openDuration: Duration(seconds: 1),
description: Text('This is Button you can\n add more details heres'),
tapTarget: Icon(Icons.navigation),
child: BottomNavigationBar(items: [
BottomNavigationBarItem(title: Text('Home'), icon: Icon(Icons.home)),
BottomNavigationBarItem(
title: Text('Notification'),
icon: Icon(Icons.notifications_active)),
]),
),
When we run the application, we ought to get the screen’s output like the underneath screen capture.
In this screen, we have defined the featureId2 inside the DescribedFeatureOverlay() widget, in which it defines its title background color and description etc.
DescribedFeatureOverlay(
featureId: 'feature2',
targetColor: Colors.white,
textColor: Colors.white,
backgroundColor: Colors.blue,
contentLocation: ContentLocation.below,
title: Text(
'Menu Icon',
style: TextStyle(fontSize: 20.0),
),
pulseDuration: Duration(seconds: 1),
enablePulsingAnimation: true,
overflowMode: OverflowMode.clipContent,
openDuration: Duration(seconds: 1),
description: Text(
'This is Button you can add more details heres\n New Info here add more!'),
tapTarget: Icon(Icons.menu),
When we run the application, we ought to get the screen’s output like the underneath screen capture.
In this screen, we have defined the featureId3 inside the DescribedFeatureOverlay() widget, in which it defines its title background color and description etc.
DescribedFeatureOverlay(
featureId: 'feature3',
targetColor: Colors.white,
textColor: Colors.black,
backgroundColor: Colors.amber,
contentLocation: ContentLocation.trivial,
title: Text(
'More Icon',
style: TextStyle(fontSize: 20.0),
),
pulseDuration: Duration(seconds: 1),
enablePulsingAnimation: true,
barrierDismissible: false,
overflowMode: OverflowMode.wrapBackground,
openDuration: Duration(seconds: 1),
description: Text('This is Button you can add more details heres'),
tapTarget: Icon(Icons.search),
child: IconButton(icon: Icon(Icons.search), onPressed: () {}),
onOpen: () async {
return true;
},
),
When we run the application, we ought to get the screen’s output like the underneath screen capture.
