ReactiveNotifier<T> class

A reactive state management solution that supports:

  • Singleton instances with key-based identity
  • Related states management
  • Circular reference detection
  • Notification overflow detection
  • Detailed debug logging
Inheritance

Constructors

ReactiveNotifier.new(T create(), {List<ReactiveNotifier>? related, Key? key, bool autoDispose = false})
Creates or returns existing instance of ReactiveNotifier
factory

Properties

autoDispose → bool
final
hashCode → int
The hash code for this object.
no setterinherited
hasListeners → bool
Whether any listeners are currently registered.
no setterinherited
keyNotifier → Key
final
notifier → T
no setterinherited
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited

Methods

addListener(VoidCallback listener) → void
Register a closure to be called when the object changes.
inherited
cleanCurrentNotifier() → bool
Attempts to remove the current instance from the global registry if it's not being used.
dispose() → void
Discards any resources used by the object. After this is called, the object is not in a usable state and should be discarded (calls to addListener will throw after the object is disposed).
from<R>([Key? key]) → R
Gets a related state by type
getStateByKey<R>(Key key) → R?
listen(void value(T data)) → T
Starts listening for changes in the ViewModel.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void
Call all the registered listeners.
inherited
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
stopListening() → void
Stops listening for changes in the ViewModel.
inherited
toString() → String
A string representation of this object.
transformState(T data(T data)) → void
transformStateSilently(T data(T data)) → void
updateSilently(T newState) → void
updateSilently Updates the value silently without notifying listeners.
updateState(T newState) → void
updateState Updates the state and notifies listeners if the value has changed.

Operators

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

Static Properties

getInstances → List<ReactiveNotifier>
no setter

Static Methods

cleanup() → void
Utility methods
cleanupByType<T>() → int
Removes all instances of a specific type from the global registry.
cleanupInstance(Key key) → bool

getInstanceByKey<T>(Key key) → ReactiveNotifier<T>
instanceCountByType<S>() → int
