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) {
  var path = Path();

  if (type == BubbleType.sendBubble) {
    path.moveTo(radius, 0);
    path.lineTo(size.width - radius - nipSize, 0);

        radius: Radius.circular(radius));

    path.lineTo(size.width - nipSize, size.height - nipSize);

    path.arcToPoint(Offset(size.width, size.height),
        radius: Radius.circular(nipSize), clockwise: false);

    path.arcToPoint(Offset(size.width - 2 * nipSize, size.height - nipSize),
        radius: Radius.circular(2 * nipSize));

    path.arcToPoint(Offset(size.width - 4 * nipSize, size.height),
        radius: Radius.circular(2 * nipSize));

    path.lineTo(radius, size.height);
