ZdsBorderClipper class

A custom clipper that allows you to clip with different offsets on each side.

This ZdsBorderClipper class extends CustomClipper<Path> and can be used to create a custom Path for a ClipPath widget with distinct border clip lengths.

All the four sides (parameters: top, bottom, left, right) have to be provided upon creating an object. These parameters represent the offsets from the corresponding sides.

If any of the insets (parameters) change, the clipping area will be recalculated.

Example

ZdsBorderClipper clipper = ZdsBorderClipper(
  top: 10,
  bottom: 10,
  left: 10,
  right: 10,
);
ClipPath(
  clipper: clipper,
  child: YourChildWidget(),
);

Methods

addListener(VoidCallback listener) → void
Register a closure to be notified when it is time to reclip.
inherited
getApproximateClipRect(Size size) Rect
Returns an approximation of the clip returned by getClip, as an axis-aligned Rect. This is used by the semantics layer to determine whether widgets should be excluded.
inherited
getClip(Size size) Path
Create a new path using the parameters provided in the constructor.
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that the object notifies when it is time to reclip.
inherited
shouldReclip(covariant CustomClipper<Path> oldClipper) bool
Reclip only if any of the inset parameters have changed.
override
toString() String
A string representation of this object.
