在Flutter中使用文本和单选按钮的动态列表视图

import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  final List<String> items = ['Item 1', 'Item 2', 'Item 3', 'Item 4'];

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Dynamic List View',
      home: Scaffold(
        appBar: AppBar(
          title: Text('Dynamic List View'),
        ),
        body: ListView.builder(
          itemCount: items.length,
          itemBuilder: (context, index) {
            return ListTile(
              title: Text(items[index]),
              leading: Radio(
                value: index,
                groupValue: selectedItemIndex,
                onChanged: (value) {
                  // 更新选中的索引
                  selectedItemIndex = value;
                },
              ),
            );
          },
        ),
      ),
    );
  }
}
