在列表视图的前导中如何制作卡片

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('Card View in List')),
        body: ListView.builder(
          itemCount: 10,
          itemBuilder: (context, index) {
            return ListTile(
              leading: Card(
                elevation: 4.0,
                child: Container(
                  width: 60,
                  height: 60,
                  decoration: BoxDecoration(
                    color: Colors.blue,
                    borderRadius: BorderRadius.circular(8.0),
                  ),
                  child: Center(
                    child: Text(
                      '${index + 1}',
                      style: TextStyle(color: Colors.white, fontSize: 20),
                    ),
                  ),
                ),
              ),
              title: Text('Item $index'),
              subtitle: Text('Description for item $index'),
            );
          },
        ),
      ),
    );
  }
}
