GetTickerProviderStateMixin mixin

Used like TickerProviderMixin but only with Get Controllers. Simplifies multiple AnimationController creation inside GetxController.

Example:

class SplashController extends GetxController with
   GetTickerProviderStateMixin {
 AnimationController first_controller;
 AnimationController second_controller;

 @override
 void onInit() {
   final duration = const Duration(seconds: 2);
   first_controller =
       AnimationController.unbounded(duration: duration, vsync: this);
   second_controller =
       AnimationController.unbounded(duration: duration, vsync: this);
   first_controller.repeat();
   first_controller.addListener(() =>
       print("Animation Controller value: ${first_controller.value}"));
   second_controller.addListener(() =>
       print("Animation Controller value: ${second_controller.value}"));
 }

Properties

hashCode → int
The hash code for this object.
no setterinherited
initialized → bool
Checks whether the controller has already been initialized.
no setterinherited
isClosed → bool
Checks whether the controller has already been closed.
no setterinherited
isDisposed → bool
no setterinherited
listenersLength → int
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.

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
containsId(Object id) → bool
inherited
containsListener(GetStateUpdate listener) → bool
inherited
createTicker(TickerCallback onTick) → Ticker
Creates a ticker with the given callback.
override
didChangeDependencies(BuildContext context) → void
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
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.
override
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 subclases. 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
toString() → String
A string representation of this object.
inherited
update([List<Object>? ids, bool condition = true]) → void
Rebuilds GetBuilder each time you call update(); Can take a List of ids, that will only update the matching GetBuilder( id: ), ids can be reused among GetBuilders like group tags. The update will only notify the Widgets, if condition is true.
inherited

Operators

operator ==(Object other) → bool
The equality operator.
