如何处理Widget上的点击手势？

import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Click Gesture Example'),
        ),
        body: Center(
          child: GestureDetector(
            onTap: () {
              // 处理点击手势的回调函数
              print('Widget被点击了！');
            },
            child: Container(
              width: 200,
              height: 200,
              color: Colors.blue,
              child: Center(
                child: Text(
                  '点击我',
                  style: TextStyle(
                    fontSize: 24,
                    color: Colors.white,
                  ),
                ),
              ),
            ),
          ),
        ),
      ),
    );
  }
}
