Implementation
@override
Path getClip(Size size) {
final path = Path()
..lineTo(0.0, size.height)
..lineTo(size.width, size.height)
..lineTo(size.width, 0.0)
..quadraticBezierTo(size.width, 0.0, size.width - 20.0, 0.0)
..lineTo(40.0, 70.0)
..quadraticBezierTo(10.0, 85.0, 0.0, 120.0)
..close();
return path;
