detach method

  1. @override
void detach()
override

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() {
  _tap.dispose();
  _longPress.dispose();
  _offset.removeListener(markNeedsPaint);
  _showCursor.removeListener(_showHideCursor);
  super.detach();
  _foregroundRenderObject?.detach();
  _backgroundRenderObject?.detach();
}
