Flutter如何从传递的数据中构建Widget列表？

class MyData {
  final String title;
  final String description;

  MyData({required this.title, required this.description});
}

class MyWidget extends StatelessWidget {
  final List<MyData> dataList;

  MyWidget({required this.dataList});

  @override
  Widget build(BuildContext context) {
    return ListView.builder(
      itemCount: dataList.length,
      itemBuilder: (context, index) {
        return ListTile(
          title: Text(dataList[index].title),
          subtitle: Text(dataList[index].description),
        );
      },
    );
  }
}

void main() {
  List<MyData> dataList = [
    MyData(title: 'Title 1', description: 'Description 1'),
    MyData(title: 'Title 2', description: 'Description 2'),
    MyData(title: 'Title 3', description: 'Description 3'),
  ];

  runApp(
    MaterialApp(
      home: Scaffold(
        body: MyWidget(dataList: dataList),
      ),
    ),
  );
}
