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, size.height);
  double x = 0;
  double y = size.height;
  double yControlPoint = size.height - heightOfPoint;
  double increment = size.width / numberOfPoints;

  if (side == Sides.BOTTOM || side == Sides.VERTICAL)
    while (x < size.width) {
      path.quadraticBezierTo(
          x + increment / 2, yControlPoint, x + increment, y);
      x += increment;
    }

  path.lineTo(size.width, 0.0);

  if (side == Sides.VERTICAL)
    while (x > 0) {
      path.quadraticBezierTo(
          x - increment / 2, heightOfPoint, x - increment, 0);
      x -= increment;
    }
  path.close();
  return path;
