detach method

  1. @override
void detach ()
override

Mark this node as detached.

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 first call their inherited detach method, and then detach all their children.

Implementation

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