-
Checks whether the controller has already been closed.

status
↔ GetStatus<
T> -
Gets the current status of the state.

- value ↔ T
-
The current value of the object. When the value changes, the callbacks
registered with addListener will be invoked.

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? -
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
idfrom future updates(), this ids are registered byGetBuilder()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, bool useEmpty = true}) → 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 -
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 -
inherited
-
toString(
) → String -
A string representation of this object.
inherited
-
update(
T fn(T? value)) → void -
inherited
Operators
-
operator ==(
Object other) → bool -
The equality operator.
