TreeValueController({TypeID? id, bool checked = false, bool expand = false, String? text, TypeData? userdata})

checked ↔ bool: getter/setter pair
expand ↔ bool: getter/setter pair
hashCode → int: The hash code for this object.

hasListeners → bool: Whether any listeners are currently registered.

addListener(VoidCallback listener) → void: Register a closure to be called when the object changes.
inherited
clear() → void: 清空子節點
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
forChecked(ForEach f) → void: 對所有被選中的節點調用函數 f
forEach(ForEach f) → dynamic: 對所有節點調用函數 f
forTopChecked(ForEach f) → void: 對所有被選中的頂層節點調用函數 f
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void: Call all the registered listeners.
inherited
removeListener(VoidCallback listener) → void: Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
toString() → String: A string representation of this object.
