Methods

addListener(GetStateUpdate listener) Disposer
Register a closure to be called when the object notifies its listeners.
inherited
addListenerId(Object? key, GetStateUpdate listener) Disposer
inherited
call([T? v]) → T?
Updates the value if a new value is provided, otherwise returns the current value.
inherited
change(GetStatus<T> status) → void
inherited
containsId(Object id) bool
inherited
containsListener(GetStateUpdate listener) bool
inherited
dispose() → void
inherited
disposeId(Object id) → void
To dispose an id from future updates(), this ids are registered by GetBuilder() or similar, so is a way to unlink the state change with the Widget from the Controller.
inherited
futurize(Future<T> body(), {T? initialData, String? errorMessage}) Future<void>
Fetches data asynchronously and updates the state accordingly.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
notifyGroupChildrens(Object id) → void
inherited
onClose() → void
Called before onDelete method. onClose might be used to dispose resources used by the controller. Like closing events, or streams before the controller is destroyed. Or dispose objects that can potentially create some memory leaks, like TextEditingControllers, AnimationControllers. Might be useful as well to persist some data on disk.
inherited
onDelete() → void
Called when the controller is removed from memory.
inherited
onInit() → void
Called immediately after the widget is allocated in memory. You might use this to initialize something for the controller.
inherited
onReady() → void
Called 1 frame after onInit(). It is the perfect place to enter navigation events, like snackbar, dialogs, or a new route, or async request.
inherited
onStart() → void
Called at the exact moment the widget is allocated in memory. It uses an internal "callable" type, to avoid any @overrides in subclasses. This method should be internal and is required to define the lifetime cycle of the subclass.
inherited
refresh() → void
inherited
refreshGroup(Object id) → void
inherited
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that the object notifies.
inherited
removeListenerId(Object id, VoidCallback listener) → void
inherited
reportAdd(VoidCallback disposer) → void
inherited
reportRead() → void
inherited
toJson() → dynamic
Converts the current value to JSON.
inherited
toString() String
Returns a string representation of the current value.
inherited
update(T fn(T? value)) → void
Updates the value based on the provided function.
