detach method
- @override
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();
Layer child = firstChild;
while (child != null) {
child.detach();
child = child.nextSibling;
}
}
