detach method

  1. @override
void detach ()
inherited

Mark this node as detached.

Typically called only from the parent's detach, and by the owner to mark the root of a tree as detached.

Subclasses with children should override this method to first call their inherited detach method, and then detach all their children.

Implementation 

@override
void detach() {
  _clipper?._reclip?.removeListener(_markNeedsClip);
  super.detach();
}
