Flutter App for Web
Hello everyone! This is my first project on Flutter Web. Today we learn about how to create web applications using Flutter. For more understanding, we create a demo on Flutter Web.
Flutter’s web help develops applications that are wealthy in intuitive content. Web helps for Flutter gives a browser-based conveyance model for Flutter mobile applications. Flutter renders web applications similarly as it will deliver your android/iOS applications. It likewise converts your project over completely to native code (HTML, CSS, JS) when you wish to deploy.

Requirements For Flutter Web App:
We have some important requirements for creating any Flutter Web App.
- > Flutter SDK. See the Flutter SDK installation instructions.
- > Chrome; debugging a web app requires the Chrome browser.
- > Optional: An IDE that supports Flutter. You can install Android Studio, IntelliJ IDEA, or Visual Studio Code and install the Flutter and Dart plugins to enable language support and tools for refactoring, running, debugging, and reloading your web app within an editor. See setting up an editor for more details.
Important’s of Flutter Web:
Some important points of flutter web:
- > Users can open your website in any screen size, you need to make it responsive.
- > Many packages that bear the web, but always examine the supported platforms before coding.
- > If you are from a web development background and if you perceive to make any changes in native code, you are highly welcome to do so. You can replace the native code the same way we can change it for Android and iOS.
- When you want to deploy your web app, you can simply run:
flutter build webHow is the performance for Flutter Web and how it is different:
- > FlutterWeb works in appealing smooth contrast to native as it creates only a single page and hence generates less cargo on the browser.
- > With the help of Flutter, you can create some great animations very easily compared to native, hence making your web app more beautiful, and it is very useful for complex web applications.
- > Flutter Web directly bear installing your website as a unfasten application (Web-App) for which you require to individually code if in native.
- > Flutter, as it is a cross-platform framework, you can add some platform-specific code without any configuration changes by which we can apply many new things to our web application.
Set Up For Flutter Web App:
- > First, we have to create a flutter project and choose the web platforms in android studio. We choose android, Ios, and Web. if we want to create an app for Linux, Windows, or Mac OS so we have to select these options
- > Then, we have to check the flutter channel, for Flutter Channel we use channel beta if your flutter channel is different then you have to change the channel to beta by using this command.
$ flutter channel beta- > After changing the channel we have to upgrade the version of flutter by using this command.
$ flutter upgrade- > When we change the channel and also upgrade the flutter we have to config or enable the web to run the flutter web app. After running this command we have to restart the Android Studio and run the project on chrome or any other browser.
$ flutter config --enable-web- > After running this command we have to restart the android studio. when its opens we find a new folder whose name is the web. In the web folder we find many files like index.html, manifest.json, and also find a folder with the name of icons.
We can start our coding part to create a better Flutter Web Application.
Implementation:
Now we create a Flutter Web Application. Give the name of the application is flutter_web_demo. In main. dart we pass the MyApp() class in the runApp() and create a stateless class with the name of MyApp() and return MaterialApp in the context and pass the new class whose name is HomePage.
return const MaterialApp(
debugShowCheckedModeBanner: false,
title: 'Flutter Demo',
home: HomePage(),
);In the HomePage class we return the Scaffold and use the properties of the scaffold, in the app-bar we pass the title of the page.
appBar: AppBar(
backgroundColor: Colors.black,
centerTitle: true,
title: const Text('Flutter Web App',
style: TextStyle(
color: Colors.white
),),
),And create a button in the center of the page. Add a text at the button which is “click me” and by using the GestureDetector() we can tap on the button and go to the new page, which is the second page of the application. On tap, we navigate the screen to a new page by using Navigator. push().
GestureDetector(
onTap: (){
Navigator.push(context,
MaterialPageRoute(builder: (context)=> const NewScreen()));
},
child: Container(
height: 50,
width: 150,
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(20),
color: Colors.black,
),
child: const Center(child: Text('CLICK ME!!!',
style: TextStyle(
color: Colors.white
),)),
),
),When we run the application, we ought to get the screen’s output like the underneath screen capture.
In the new screen whose class name is NewScreen(), we return Scaffold and pass text in the body of it.
return const Scaffold(
body: Center(child: Text('Welcome to Flutter Web App...',
style: TextStyle(
fontStyle: FontStyle.italic,
fontSize: 30,
fontWeight: FontWeight.w500,
color: Colors.teal
),)),
);When we run the application, we ought to get the screen’s output like the underneath screen capture.
Conclusion:
I hope you like my article. Flutter web is extremely useful for web developers and also for app developers. Because of this, we don’t need to learn HTML, CSS, or JS. There are many browsers like Chrome, Safari, Edge and Firefox, Chrome (on Windows, macOS, and Linux), and Edge (on Windows).
