如何知道在flutter中点击了哪个按钮

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('Button Click Example'),
        ),
        body: Center(
          child: MyButton(),
        ),
      ),
    );
  }
}

class MyButton extends StatelessWidget {
  void _onButtonClicked(String buttonName) {
    print('Button $buttonName clicked');
  }

  @override
  Widget build(BuildContext context) {
    return Column(
      mainAxisAlignment: MainAxisAlignment.center,
      children: <Widget>[
        ElevatedButton(
          onPressed: () => _onButtonClicked('Button1'),
          child: Text('Button 1'),
        ),
        SizedBox(height: 20),
        ElevatedButton(
          onPressed: () => _onButtonClicked('Button2'),
          child: Text('Button 2'),
        ),
      ],
    );
  }
}
