Features

• Single codebase for multiple platforms
• Fast development with hot reload
• Expressive and flexible UI
• Native performance
• Strong typing with Dart
• Rich widget library

Getting Started

flutter create my_app
cd my_app
flutter run

Basic Example

import 'package:flutter/material.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      home: MyHomePage(),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({super.key});

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  int _counter = 0;

  void _incrementCounter() {
    setState(() {
      _counter++;
    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('Flutter Demo'),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            Text('Count: $_counter'),
            ElevatedButton(
              onPressed: _incrementCounter,
              child: const Text('Increment'),
            ),
          ],
        ),
      ),
    );
  }
}
