如何在Flutter上将可点击的正方形图像更改为圆形图像？

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('Circle Image'),
        ),
        body: Center(
          child: GestureDetector(
            onTap: () {
              print('Image clicked');
            },
            child: ClipOval(
              child: Image.network(
                'https://example.com/image.jpg',
                width: 200,
                height: 200,
                fit: BoxFit.cover,
              ),
            ),
          ),
        ),
      ),
    );
  }
}
