Answer 1

Create a custom widget:

class MyCustomWidget extends StatelessWidget {
  final String text;
  final VoidCallback? onTap;

  const MyCustomWidget(this.text, {
    Key? key,
    this.onTap,
  }) : super(key: key);

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

MyCustomWidget(
  'My button',
  onTap: () {},
)
