有没有办法在Flutter中在文本内部作画？

import 'package:flutter/material.dart';

class TextWithDrawing extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Text with Drawing'),
      ),
      body: Center(
        child: CustomPaint(
          painter: MyPainter(),
          child: Text(
            'Hello World',
            style: TextStyle(fontSize: 24),
          ),
        ),
      ),
    );
  }
}

class MyPainter extends CustomPainter {
  @override
  void paint(Canvas canvas, Size size) {
    // 绘制一个红色的矩形
    final paint = Paint()..color = Colors.red;
    canvas.drawRect(Rect.fromLTWH(0, 0, size.width, size.height), paint);
  }

  @override
  bool shouldRepaint(covariant CustomPainter oldDelegate) {
    return false; // 不需要重新绘制
  }
}
