dependencies
→ Set<
BaseNotifier> -
A collection of notifiers that this notifier depends on.
finalinherited
-
dependents
→ Set<
BaseNotifier> -
A collection of notifiers that depend on this notifier.
They will be disposed when this notifier is disposed.
finalinherited
- disposed → bool
-
Whether this notifier is disposed.
no setterinherited
- hashCode → int
-
The hash code for this object.
no setterinherited
-
provider
→ BaseProvider<
BaseNotifier< ?void> , void> -
The provider that created this notifier.
This is only available after the initialization.

- requireBuildContext → bool
-
If this is true, initializing must be done by ViewModelBuilder of the refena_flutter package.
This flag is needed to throw an exception if the user forgets to use ViewModelBuilder.

- runtimeType → Type
-
A representation of the runtime type of the object.

- state ↔ void
-
Gets the current state.

Methods
-
addListener(
Rebuildable rebuildable, ListenerConfig< void> config) → void -
inherited
-
cleanupListeners(
) → void -
inherited
-
describeState(
void state) → String -
Override this to provide a customized description of the state.
This is used by the built-in observers for improved logging.
inherited
-
dispose(
) → void -
This is called on Ref.dispose.
You can override this method to dispose resources.
inherited
-
getListeners(
) → List< Rebuildable> -
inherited
-
getStream(
) → Stream< NotifierEvent< void> > -
inherited
-
init(
) → void - Override postInit to run code after the notifier is initialized.
-
internalSetup(
ProxyRef ref, BaseProvider< BaseNotifier< ? provider) → voidvoid> , void> -
Handles the actual initialization of the notifier.
Calls init internally.
inherited
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
notifyListeners(
) → void - Call this method whenever the state changes. This will notify all listeners.
-
postInit(
) → void -
Override this to provide a custom post initialization.
The initial state is already set at this point.
inherited
-
removeListener(
Rebuildable rebuildable) → void -
inherited
-
toString(
) → String -
A string representation of this object.
inherited
-
updateShouldNotify(
void prev, void next) → bool - Override this if you want to a different kind of equality.
Operators
-
operator ==(
Object other) → bool -
Subclasses should not override this method.
It is used internally by dependencies and dependents.
