如何从Flutter中的数据结构内容创建widget？

class MyWidget extends StatelessWidget {
  final MyData data;

  MyWidget(this.data);

  @override
  Widget build(BuildContext context) {
    return Container(
      color: data.backgroundColor,
      child: Text(
        data.text,
        style: TextStyle(
          color: data.textColor,
          fontSize: data.textSize,
        ),
      ),
    );
  }
}

class MyData {
  final String text;
  final Color backgroundColor;
  final Color textColor;
  final double textSize;

  MyData({
    required this.text,
    required this.backgroundColor,
    required this.textColor,
    required this.textSize,
  });
}

void main() {
  MyData data = MyData(
    text: 'Hello, Flutter!',
    backgroundColor: Colors.blue,
    textColor: Colors.white,
    textSize: 20.0,
  );

  runApp(MyApp(data));
}

class MyApp extends StatelessWidget {
  final MyData data;

  MyApp(this.data);

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        body: Center(
          child: MyWidget(data),
        ),
      ),
    );
  }
}
