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() {
  super.detach();
  ChildType? child = _firstChild;
  while (child != null) {
    child.detach();
    final ParentDataType childParentData = child.parentData! as ParentDataType;
    child = childParentData.nextSibling;
  }
}
