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) {
  Path path = Path();
  path.lineTo(0.0, 0.0);
  path.lineTo(0.0, size.height);
  if (dy > -20) {
    path.quadraticBezierTo((size.width / 2) - 28, size.height - 20,
        size.width / 2, size.height - dy - 56);
  }
  path.lineTo(size.width / 2, size.height - (dy == 0 ? 0 : (dy + 56)));
  if (dy > -20) {
    path.quadraticBezierTo(
        (size.width / 2) + 28, size.height - 20, size.width, size.height);
  }
  path.lineTo(size.width, size.height);
  path.lineTo(size.width, 0);
  path.lineTo(0.0, 0.0);
  return path;
