getClip method

  1. @override
Path getClip(
  1. Size size
)
override

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.lineTo(size.width - radius - nipSize, 0);
    path.arcToPoint(Offset(size.width - nipSize, radius),
        radius: Radius.circular(radius));

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

    path.quadraticBezierTo(
        size.width - nipSize, size.height - nipSize, size.width, size.height);
    path.quadraticBezierTo(size.width - nipSize, size.height - nipSize,
        size.width - sizeRatio * nipSize, size.height - nipSize);

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

    path.arcToPoint(Offset(0, size.height - radius - nipSize),
        radius: Radius.circular(radius));

    path.lineTo(0, radius);
    path.arcToPoint(Offset(radius, 0), radius: Radius.circular(radius));
  } else {
    path.lineTo(size.width - radius, 0);
    path.arcToPoint(Offset(size.width, radius),
        radius: Radius.circular(radius));
    path.lineTo(size.width, size.height - radius - nipSize);
    path.arcToPoint(Offset(size.width - radius, size.height - nipSize),
        radius: Radius.circular(radius));

    path.lineTo(sizeRatio * nipSize, size.height - nipSize);
