addListener(VoidCallback listener) → void: Register a closure to be called when the object changes.
inherited
clearAll() → void
closeOverlay() → void
dispose() → void: Discards any resources used by the object.
override
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void: Call all the registered listeners.
inherited
onSearch(String? searchColumn, String query) → Future<void>
openOverlay() → void
removeItem(T item) → void
removeListener(VoidCallback listener) → void: Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
selectByName(String name) → Future<bool>: Programmatically selects an item matching name. For async dropdowns: does a targeted API search by name first (large page), then falls back to the already-loaded items list. For sync dropdowns: searches the provided items list. Returns true if an item was found and selected.
override
syncExternalSelectedItems(List<T> externalSelectedItems) → void: Sincronizza lo stato interno con eventuali aggiornamenti esterni (es. selectedValues valorizzati dopo un preload asincrono).
toggleOverlay() → void
toString() → String: A string representation of this object.
