@override
Path getClip(Size size) {
  Path path = Path();

  path.moveTo(0, 0); // Top-left corner
  path.lineTo(size.width, 0); // Top-right corner
  path.lineTo(size.width,
      size.height - size.height * 0.2); // Bottom-right before triangle
  path.lineTo(size.width / 2, size.height); // Bottom triangle tip (sharp)
  path.lineTo(
      0, size.height - size.height * 0.2); // Bottom-left before triangle
  path.close(); // Complete the path

  return path;
