addListener(Function listener, {Object? target, bool once = false, bool immediate = false}) → void: Register a listener for a specific property target can be an element or elements list like [ property1, property2 ]
inherited
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).

fromMap(Map<String, dynamic> props) → void: Initialize properties with map
inherited
getProperty(String propertyName) → Object?: Implement getProperty to return the value of a property by its name.

inherited
notifyListeners([String? target]) → void: Notify listeners for a specific element
inherited
promise(VoidCallback listener) → void: register a listener in promise's prototype consumed immediately or awaited once via Signal(True).
