getClip method

@override Path getClip(Size size)

Returns a description of the clip given that the render object being clipped is of the given size.

Implementation

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

  // Start from bottom-left
  path.moveTo(0, size.height);

  // Line up to bottom of left corner
  path.lineTo(0, 20);

  // Top-left arc (rounded corner)
  path.quadraticBezierTo(
    0, // Control point X
    0, // Control point Y
    20, // End point X
    0, // End point Y
  );

  // Top line to top-right arc
  path.lineTo(size.width - 20, 0);

  // Top-right arc (rounded corner)
  path.quadraticBezierTo(
    size.width, // Control point X
    0, // Control point Y
    size.width, // End point X
    20, // End point Y
  );

  // Line down to bottom-right
  path.lineTo(size.width, size.height);

  // Close the path
  path.close();

  return path;
