Step 2: Setting Up Android Studio

• Open Android Studio and navigate to Preferences.
• In the Plugins section, search for and install the Flutter and Dart plugins.
• Restart Android Studio after installation.

Step 3: Create a New Flutter Project

Once Android Studio is set up, you can create a new Flutter project:

flutter create my_flutter_web_app

This command generates a new Flutter project with a sample web layout.

Step 4: Enabling Web Support

To enable web support in your Flutter project, run the following command in your terminal:

flutter config --enable-web

With web support enabled, you can use the command below in your project’s root directory to launch the web app:

flutter run -d chrome

Building a Simple Flutter Web Application

Let’s walk through building a simple Flutter web application. This app will showcase a basic layout with a few interactive elements.

Step 1: Define the App Structure

Open the lib/main.dart file in your project and define a simple app structure:

import 'package:flutter/material.dart';
void main() {

  runApp(MyApp());

}
class MyApp extends StatelessWidget {

  @override

  Widget build(BuildContext context) {

    return MaterialApp(

      title: 'Flutter Web Demo',

      theme: ThemeData(primarySwatch: Colors.blue),

      home: HomePage(),

    );

  }

}
class HomePage extends StatelessWidget {

  @override

  Widget build(BuildContext context) {

    return Scaffold(

      appBar: AppBar(title: Text('Welcome to Flutter Web')),

      body: Center(child: Text('Hello, Flutter Web!')),

    );

  }

}

Step 2: Add Interaction

Now, let’s add some interactivity by including a button that changes the text on the screen:

class HomePage extends StatefulWidget {

  @override

  _HomePageState createState() => _HomePageState();

}
class _HomePageState extends State {

  String message = 'Hello, Flutter Web!';
void updateMessage() {

    setState(() {

      message = 'You clicked the button!';

    });

  }
@override

  Widget build(BuildContext context) {

    return Scaffold(

      appBar: AppBar(title: Text('Welcome to Flutter Web')),

      body: Center(

        child: Column(

          mainAxisAlignment: MainAxisAlignment.center,

          children: [

            Text(message),

            SizedBox(height: 20),

            ElevatedButton(

              onPressed: updateMessage,

              child: Text('Click Me'),

            ),

          ],

        ),

      ),

    );

  }

}

Step 3: Running the Application

After adding the interactivity, save the file and run your application again using:

flutter run -d chrome

This will launch your web application in the browser, and you will see your text and button.
