如何在flutter中从listview元素的文本字段中传递数据？

class MyListView extends StatelessWidget {
  final List<String> items;

  MyListView({required this.items});

  @override
  Widget build(BuildContext context) {
    return ListView.builder(
      itemCount: items.length,
      itemBuilder: (context, index) {
        return ListTile(
          title: Text(items[index]),
          onTap: () {
            // 在这里调用回调函数，将数据传递给父级Widget
          },
        );
      },
    );
  }
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    List<String> items = ['Item 1', 'Item 2', 'Item 3'];

    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Flutter ListView'),
        ),
        body: MyListView(
          items: items,
          onItemSelected: (selectedItem) {
            // 在这里处理从ListView中选中的文本字段数据
            print('Selected item: $selectedItem');
          },
        ),
      ),
    );
  }
}
