bool? debugSubtreeNeedsAddToScene
visibleForTesting">@visibleForTesting

Whether this or any descendant layer in the subtree needs addToScene.

This is for debug and test purpose only. It only becomes valid after calling updateSubtreeNeedsAddToScene.

Implementation

@visibleForTesting
bool? get debugSubtreeNeedsAddToScene {
  bool? result;
  assert(() {
    result = _needsAddToScene;
    return true;
  }());
  return result;
}
