Constructors

StreamEventProvider(T value, {OnUpdate<T>? onUpdate, OnEvent<E>? onEvent}): Base constructor implemented by classes that provide an event listener.

hasEvent → bool: Returns true if there are any active event listeners or if onEvent is set.

hasEventListener → bool: Returns true if there are any active event listeners.
no setter
hashCode → int: The hash code for this object.

hasUpdate → bool: Returns true if there are any active update listeners or if onUpdate is set.
no setter
isObserved → bool: Returns true if there are any active listeners or if onUpdate is not null.

numberOfEventListeners → int: Returns the number of active event listeners.

numberOfListeners → int: Returns the number of active listeners.

onEvent ↔ OnEvent<E>?: Called when an element is added, removed, or updated in the list/map before onUpdate is called and before the listeners are notified of the new value.
getter/setter pair
onUpdate ↔ OnUpdate<T>?: Called after value is updated, before the listeners are notified.

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

addEventListener(OnEvent<E> onEvent) → StreamSubscription<E>: Registers a new StreamSubscription that provides a CollectionEvent denoting when any elements have been added, removed, or updated in the collection.
addListener(OnUpdate<T> onUpdate) → StreamSubscription<T>: Creates, stores and returns a listener.
inherited
dispose() → void: Cancels any active listeners and closes the stream.
override
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
notifyEventListeners(E event) → void: Notifies all subscribed event listeners of an event.
notifyListeners(T event) → void: Notifies all subscribed listeners of an event.
inherited
removeEventListener() → void: Cancels and removes an event listener.
removeListener() → void: Cancels and removes a StreamSubscription.
inherited
setValue(T value) → void: Sets the observable value to value without notifying the event listeners.
inherited
toString() → String: A string representation of this object.
