How can I create custom widgets in Flutter?

Creating custom widgets in Flutter involves extending the StatelessWidget or StatefulWidget classes. You can define your own widget by overriding the build method.

Can you give me an example of a simple custom widget?

Sure! Here's a simple example of a custom button widget:

class CustomButton extends StatelessWidget {
  final String label;
  final VoidCallback onPressed;

  CustomButton({required this.label, required this.onPressed});

  @override
  Widget build(BuildContext context) {
    return ElevatedButton(
      onPressed: onPressed,
      child: Text(label),
    );
  }
}

How do I use this CustomButton in my app?

You can use the CustomButton in your app like this:

CustomButton(
  label: 'Click Me',
  onPressed: () {
    print('Button pressed!');
  },
),

What are some best practices for creating custom widgets?

Some best practices include keeping your widgets small and focused, using composition over inheritance, and making them reusable.
