Properties

data ↔ List?: getter/setter pair
hashCode → int: The hash code for this object.
no setterinherited
hasListeners → bool: Whether any listeners are currently registered.
no setterinherited
rootController → NodeController: Get the controller for the root node. If null will be initialized according to the data
no setter
rootDataNode ↔ dynamic: getter/setter pair
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited

Methods

addListener(VoidCallback listener) → void: Register a closure to be called when the object changes.
inherited
collapseItem(TreeNode treeNode) → void: Begin collapse
createNewNodeController(NodeController parentController, int index) → NodeController
createNodeController(NodeController parentController, List<int> indexes) → List<NodeController>: Create controllers for each child node
dataForTreeNode(TreeNodeItem nodeItem) → dynamic: Gets the data associated with each item
dispose() → void: Discards any resources used by the object. After this is called, the object is not in a usable state and should be discarded (calls to addListener will throw after the object is disposed).
inherited
expandItem(TreeNode treeNode) → void: Begin expand
expandOrCollapse(int index) → TreeNode: Click item to expand or contract or collapse index The index of the clicked item
indexOfItem(dynamic item) → int: The index of the specified item
insertAllAtFront(NodeData? parent, List<NodeData> newNodes, {bool closeCanInsert = false}) → void: Appends all nodes to the head of parent. parent The parent node newNode The node will be insert closeCanInsert Can insert when parent closed
insertAtFront(NodeData? parent, NodeData newNode, {bool closeCanInsert = false}) → void: Insert a node in the head parent The parent node newNode The node will be insert closeCanInsert Can insert when parent closed
insertAtIndex(int index, dynamic parent, NodeData newNode, {bool closeCanInsert = false}) → void: Inserts a node at position index in parent. The index value must be non-negative and no greater than length.
insertAtRear(NodeData? parent, NodeData newNode, {bool closeCanInsert = false}) → void: Insert a node in the end parent The parent node newNode The node will be insert closeCanInsert Can insert when parent closed
isExpanded(dynamic item) → bool
itemChildrenLength(dynamic item) → int
levelOfNode(dynamic item) → int: The level of the specified item
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void: Call all the registered listeners.
inherited
numberOfVisibleChild() → int: Gets the number of visible children of the ListTreeView
parentOfItem(dynamic item) → NodeData?: Gets the data information for the parent node
rebuild() → void
removeItem(dynamic item) → void: remove
removeItemAtIndexes(int index, dynamic parent) → void
removeListener(VoidCallback listener) → void: Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
selectAllChild(dynamic item) → void
selectItem(dynamic item) → void: select
toString() → String: A string representation of this object.
inherited
treeData(List? data) → void
treeNodeOfIndex(int index) → TreeNode: TreeNode by index

Operators

operator ==(Object other) → bool: The equality operator.
