Methods

addListener(GetStateUpdate listener) → Disposer
Adds a listener and returns a Disposer to remove it later.
inherited
addListenerId(Object? key, GetStateUpdate listener) → Disposer
Adds a listener to a specific group ID.
inherited
containsId(Object id) → bool
Checks if a specific ID exists in the group.
inherited
containsListener(GetStateUpdate listener) → bool
Checks if a given listener is already registered.
inherited
dispose() → void
Disposes all listeners in the group.
inherited
disposeId(Object id) → void
Disposes of a specific ID from future updates.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
notifyGroupChildren(Object id) → void
Notifies all children of a given group ID.
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
onEndScroll() → Future<void>
Called when the scroll reaches the bottom. Implement this method to load more content or perform other actions.
onInit() → void
Called immediately after the widget is allocated in memory. You might use this to initialize something for the controller.
override
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
onTopScroll() → Future<void>
Called when the scroll reaches the top. Implement this method to refresh content or perform other actions.
refresh() → void
Notifies all registered listeners of an update.
inherited
refreshGroup(Object id) → void
Refreshes all listeners associated with a specific ID.
inherited
removeListener(VoidCallback listener) → void
Removes a registered listener.
inherited
removeListenerId(Object id, VoidCallback listener) → void
Removes a specific listener from a group by ID.
inherited
reportAdd(VoidCallback disposer) → void
Reports a new listener addition.
inherited
reportRead() → void
Reports that a read operation has occurred.
inherited
toString() → String
A string representation of this object.
inherited
update([List<Object>? ids, bool condition = true]) → void
Rebuilds the associated widgets.

Operators

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