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.

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.

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

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