Implementation
@override
Path getClip(Size size) {
Path path = Path();
double notchWidth = 100;
double notchHeight = 20;
double notchRadius = 30;
// Start from bottom left
path.lineTo(size.width / 2 - notchWidth / 2, 0);
// Create notch curve
path.quadraticBezierTo(
size.width / 2 - notchWidth / 2 + notchRadius,
-notchHeight,
size.width / 2,
-notchHeight,
);
path.quadraticBezierTo(
size.width / 2 + notchWidth / 2 - notchRadius,
-notchHeight,
size.width / 2 + notchWidth / 2,
0,
);
path.lineTo(size.width, 0);
path.lineTo(size.width, size.height);
path.lineTo(0, size.height);
path.close();
