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 = Path();
  path.lineTo(0, size.height);
  double xPosBottom = 0.0;
  double yPosBottom = size.height;
  final double increment = size.width / 2;
  while (xPosBottom < size.width) {
    xPosBottom += increment;
    yPosBottom = yPosBottom == size.height ? size.height - 5 : size.height;
    path.lineTo(xPosBottom, yPosBottom);
  }
  path.lineTo(size.width, 0);
  double xPosTop = size.width;
  double yPosTop = 0;
  final double decrement = size.width / 200;
  while (xPosTop > 0) {
    xPosTop -= decrement;
    yPosTop = yPosTop == 0 ? 15 : 0;
    path.lineTo(xPosTop, yPosTop);
  }
  path.lineTo(0, 0);
  path.close();
  return path;
