Static Methods

collapseNode<T>({required List<FlatNode<T>> currentList, required String nodeId}) → ({int index, List<FlatNode<T>> list})?

Incrementally collapse a node: remove all descendants that follow it. Returns the new list and the index of the collapsed node, or null if the node was not found (caller should fall back to full rebuild).

expandNode<T>({required List<FlatNode<T>> currentList, required String nodeId, required Set<String>? expandedNodeIds}) → ({int index, List<FlatNode<T>> list})?

Incrementally expand a node: insert its flattened subtree right after it. Returns the new list and the index of the expanded node, or null if the node was not found (caller should fall back to full rebuild).

flatten<T>({required List<Node<T>> nodes, required Set<String>? expandedNodeIds, int depth = 0, bool isRoot = true, List<bool> ancestorIsLastFlags = const []}) → List<FlatNode<T>>

Flattens a tree of nodes into a list of FlatNodes, only including children of expanded nodes.
