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 == MessageType.SEND) {
    path.lineTo(size.width - nipRadius, 0);
    path.arcToPoint(Offset(size.width - nipRadius, nipRadius),
        radius: Radius.circular(nipRadius));
    path.lineTo(size.width - nipWidth, nipHeight);
    path.lineTo(size.width - nipWidth, size.height - bubbleRadius);
    path.arcToPoint(Offset(size.width - nipWidth - bubbleRadius, size.height),
        radius: Radius.circular(bubbleRadius));
    path.lineTo(bubbleRadius, size.height);
    path.arcToPoint(Offset(0, size.height - bubbleRadius),
        radius: Radius.circular(bubbleRadius));
    path.lineTo(0, bubbleRadius);
    path.arcToPoint(Offset(bubbleRadius, 0),
        radius: Radius.circular(bubbleRadius));
  } else {
    path.lineTo(size.width - bubbleRadius, 0);
    path.arcToPoint(Offset(size.width, bubbleRadius),
        radius: Radius.circular(bubbleRadius));
    path.lineTo(size.width, size.height - bubbleRadius);
    path.arcToPoint(Offset(size.width - bubbleRadius, size.height),
        radius: Radius.circular(bubbleRadius));
    path.lineTo(bubbleRadius + nipWidth, size.height);
    path.arcToPoint(Offset(nipWidth, size.height - bubbleRadius),
        radius: Radius.circular(bubbleRadius));
