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, size.height);
  double x = 0.0;
  double y = size.height;
  double increment = size.width / numberOfPoints / 2;

  if (side == Sides.BOTTOM || side == Sides.VERTICAL)
    while (x < size.width) {
      x += increment;
      y = (y == size.height) ? size.height - heightOfPoint : size.height;
      path.lineTo(x, y);
    }
  path.lineTo(size.width, 0.0);

  x = size.width;
  y = 0.0;
  if (side == Sides.VERTICAL)
    while (x > 0) {
      x -= increment;
      y = (y == 0) ? 0 + heightOfPoint : 0;
      path.lineTo(x, y);
    }

  path.close();
  return path;
