Flutter is an open-source User Interface SDK that is Software Development Kit. Flutter is an open-source project, and it is maintained by Google. Currently, in March 2021. Google has been released another new version of flutter that is Flutter 2. Flutter as a software development kit is great, but while building a big application, there will be some problems or bugs in the code that has to be debugged.

Flutter provides multiple debugging tools such as timeline inspector, memory and performance inspector, and else. These tools ease up the debugging process for a developer, below are listed different tools for debugging flutter apps.

Hello friends, I will talk about my new blog on Explore Onboarding Overlay In Flutter. We will also implement an Explore Onboarding Overlay Widget demo and use them in your flutter applications. So let’s get started.

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 It means that you can use one programming language and one codebase to create two different apps (for iOS and Android).”.

Onboarding Overlay :

The Onboarding Overlay Package animated implements onboarding overlay following custom design guidelines, in this, we can use any widget within onboarding overlay, we use it to introduce the user to a feature about which they wouldn’t you know. Onboarding overlay is a flexible onboarding widget that can start and stop with an arbitrary number of steps and arbitrary starting points.

Implementation :

You need to implement it in your code respectively :

Step 1: Add dependencies.

Add dependencies to pubspec — yaml file.

dependencies:
onboarding_overlay: ^2.1.0

Step 2: import the package :

import 'package:onboarding_overlay/onboarding_overlay.dart';

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

Code Implementation :

Create a new dart file called onboarding_overlay_demo.dart inside the libfolder.

First of all, we have to define our GlobalKey and inside it, whose name is onBoardingKey and scaffoldKey.

final GlobalKey<OnboardingState> onboardingKey = GlobalKey<OnboardingState>();final GlobalKey<ScaffoldState> scaffoldKey = GlobalKey<ScaffoldState>();

Now we will use the Onboarding Widget inside which we will use Steps property inside which we have used some different types of properties like its title, titleTextColor, labelBoxPadding, labelBoxDecoration, bodyText, etc. which we have used a code below can be understood with the help of reference.

OnboardingStep(
focusNode: focusNodes[0],
title: 'Tap anywhere to continue Tap anywhere to continue',
titleTextColor: Colors.black,
bodyText: 'Tap anywhere to continue Tap anywhere to continue',
labelBoxPadding: const EdgeInsets.all(16.0),
labelBoxDecoration: BoxDecoration(
shape: BoxShape.rectangle,
borderRadius: const BorderRadius.all(Radius.circular(8.0)),
color: const Color(0xFF00E1FF),
border: Border.all(
color: const Color(0xFF1E05FB),
width: 1.0,
style: BorderStyle.solid,
)),
arrowPosition: ArrowPosition.bottomCenter,
hasArrow: true,
hasLabelBox: true,
fullscreen: true,
),

Code File :

import 'package:flutter/material.dart';
import 'package:onboarding_overlay/onboarding_overlay.dart';class OnBoardingOverlayDemo extends StatefulWidget {
const OnBoardingOverlayDemo({
Key? key,
required this.focusNodes,
}) : super(key: key);

final List<FocusNode> focusNodes;

@override
_OnBoardingOverlayDemoState createState() => _OnBoardingOverlayDemoState();
}

class _OnBoardingOverlayDemoState extends State<OnBoardingOverlayDemo> {
late int _counter;

@override
void initState() {
super.initState();
_counter = 0;
}

@override
void dispose() {
super.dispose();
}

void _increment(BuildContext context) {
setState(() {
_counter++;
Onboarding.of(context)!.show();
});
}

@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
leading: IconButton(
focusNode: widget.focusNodes[4],
icon: const Icon(Icons.menu),
onPressed: () {},
),
title: Focus(
focusNode: widget.focusNodes[3],
child: const Text('Title'),
),
),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Focus(
focusNode: widget.focusNodes[0],
child: const Text('You have pushed the button this many times:'),
),
Focus(
focusNode: widget.focusNodes[2],
child: Text(
'$_counter',
style: Theme.of(context).textTheme.headline4,
),
),
],
),
),
floatingActionButton: FloatingActionButton(
focusNode: widget.focusNodes[1],
onPressed: () {
_increment(context);
},
child: const Icon(Icons.add),
),
);
}
}

Conclusion :

In this article, I have explained Explore Onboarding Overlay In Flutter, which you can modify and experiment with according to your own, this little introduction was from the Explore Onboarding Overlay In Flutter demo from our side.

I hope this blog will provide you with sufficient information on Trying up the Explore Onboarding Overlay In Flutter in your flutter project. We showed you what the Explore Onboarding Overlay In Flutter is and work on it in your flutter applications, So please try it.
