detach method

  1. @override
void detach()

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.

Implementations of this method should end with a call to the inherited method, as in super.detach().


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