Methods

addListener(VoidCallback listener) → void

Register a closure to be notified when it is time to reclip.

inherited

getApproximateClipRect(Size size) → Rect

Returns a description of the clip given that the render object being clipped is of the given size.

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<Rect> oldClipper) → bool

Called whenever a new instance of the custom clipper delegate class is provided to the clip object, or any time that a new clip object is created with a new instance of the custom clipper delegate class (which amounts to the same thing, because the latter is implemented in terms of the former).

override
