有没有办法在flutter中复制具有文本样式格式的文本文件数据

import 'package:flutter/material.dart';
import 'package:flutter/services.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Copy Text with Styles'),
        ),
        body: Center(
          child: CopyTextWidget(),
        ),
      ),
    );
  }
}

class CopyTextWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    final text = RichText(
      text: TextSpan(
        children: [
          TextSpan(text: 'Hello ', style: TextStyle(fontSize: 20)),
          TextSpan(text: 'World!', style: TextStyle(fontSize: 30, color: Colors.blue)),
        ],
      ),
    );

    return Column(
      mainAxisAlignment: MainAxisAlignment.center,
      children: [
        text,
        SizedBox(height: 20),
        ElevatedButton(
          onPressed: () {
            copyTextWithStyles(text);
          },
          child: Text('Copy Text'),
        ),
      ],
    );
  }

  void copyTextWithStyles(RichText text) async {
    final textController = TextEditingController();
    textController.text = text.toString();
    await Clipboard.setData(ClipboardData(text: textController.text));
    ScaffoldMessenger.of(context).showSnackBar(SnackBar(content: Text('Text copied to clipboard')));
  }
}
