detach method

  1. @override
void detach()

Mark this render object as detached from its PipelineOwner.

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 detach all their children after calling the inherited method, as in super.detach().

Implementation

@override
void detach() {
  // It's possible that the renderObject be detached during mouse events
  // dispatching, set the [MouseTrackerAnnotation.validForMouseTracker] false
  // to prevent the callbacks from being called.
  _validForMouseTracker = false;
  super.detach();
}
