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().


void detach() {
  _painter = null;
