Flutter StatefulWidget Example

Here's a complete example showing how to create a stateful widget:

DARTCopy
class MyWidget extends StatefulWidget {
  const MyWidget({Key? key}) : super(key: key);

  @override
  State<MyWidget> createState() => _MyWidgetState();
}

class _MyWidgetState extends State<MyWidget> {
  int counter = 0;

  @override
  Widget build(BuildContext context) {
    return Text('Counter: $counter');
  }
}

Key Points

• StatefulWidget holds mutable state
• Use setState() to trigger rebuilds
• Separate State class manages the data

Check out the docs: https://flutter.dev

Use inline code like setState() for updates.
