void remove(TreeNode<Object?> node, { bool notify = true, })

Implementation

void remove(TreeNode node, {bool notify = true}) {
  assert(node.isAttached, '''
    Node must be attached in order for it to be able to be removed
    ''');
  final oldIndex = node.index;
  final movedSiblings = node.siblings.sublist(oldIndex + 1);
  _cascadeRemove(node);
  if (_onMoved != null) {
    for (final (index, sibling) in movedSiblings.indexed) {
      _onMoved(sibling, oldIndex + index, sibling.parent, sibling.parent);
    }
  }

  if (_onChanged != null) {
    _onChanged();
  }
  if (notify) notifyListeners();
}
