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}"));
}

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 - Callback invoked when the dependencies of this widget change.
-
dispose(
) → void -
inherited
-
disposeId(
Object id) → void -
To dispose an
id
from 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 -
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 -
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
-
toString(
) → String -
A string representation of this object.
inherited
-
update(
[List< Object> ? ids, bool condition = true]) → void -
Rebuilds the associated
GetBuilder
widgets.inherited
Operators
-
operator ==(
Object other) → bool -
The equality operator.
