有没有办法在Flutter中处理应用程序状态下的列表？

class MyListWidget extends StatefulWidget {
  @override
  _MyListWidgetState createState() => _MyListWidgetState();
}

class _MyListWidgetState extends State<MyListWidget> {
  List<String> items = ['Item 1', 'Item 2', 'Item 3'];

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('My App'),
        ),
        body: MyListWidget(),
      ),
    );
  }
}
