      padding: EdgeInsets.all(16.0),
      color: Colors.red,
      child: Text(

    effect: ScaleEffect.withRipple(
      scaleFactor: 0.9,
      rippleEffect: RippleEffect(color: Colors.green),

Complete Example #

Here’s a more comprehensive example demonstrating the use of both RippleEffect and ScaleEffect:

import 'package:flutter/material.dart';

}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(

            },
            effect: ScaleEffect.withRipple(
              scaleFactor: 0.95,
              rippleEffect: RippleEffect(
                color: Colors.blue.withOpacity(0.3),
              ),
