如何使带有边框半径的Flutter ListView像一个图片

import 'package:flutter/material.dart';

class CustomListView extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Container(
      decoration: BoxDecoration(
        borderRadius: BorderRadius.circular(10), // 设置边框半径
        border: Border.all(
          color: Colors.grey, // 设置边框颜色
          width: 1.0, // 设置边框宽度
        ),
      ),
      child: ListView.builder(
        itemCount: 10, // 设置列表项数量
        itemBuilder: (BuildContext context, int index) {
          return ListTile(
            title: Text('Item $index'),
          );
        },
      ),
    );
  }
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Flutter ListView'),
        ),
        body: Center(
          child: CustomListView(), // 使用自定义的ListView Widget
        ),
      ),
    );
  }
}
