Consider a code snippet as below:

import 'dart:math' as math;

class MyPainter extends CustomPainter {
  void paint(Canvas canvas, Size size) {;

    // rotate the canvas
    final degrees = 15;
    final radians = degrees * math.pi / 180;

    // draw the text
    final textStyle = TextStyle(color:, fontSize: 30);
    final textSpan = TextSpan(text: 'Hello, world.', style: textStyle);
    TextPainter(text: textSpan, textDirection: TextDirection.ltr)
      ..layout(minWidth: 0, maxWidth: size.width)
      ..paint(canvas, Offset(0, 0));


  bool shouldRepaint(CustomPainter old) {
