ObservableComposite<T> class

Merges multiple updates of ObserveAwares and emits a single update notification stream.

Inheritance

Constructors

ObservableComposite({bool coalesce = false, List<ObserveAware>? values, bool withStackTrace = false}): Changes are published synchronously by default. When coalesce is set, the changes in the current execution block are collected, and only the one event with null value will be published (in an async scheduled microtask).

changes → Stream<Change<T?>>: Provides a stream of change pairs.

hashCode → int: The hash code for this object.
no setterinherited
hasListener → bool: Whether there is a subscriber to stream or changes.
no setterinherited
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
stream → Stream<T?>: Provides a stream of object values when the reference changes.
no setterinherited

dispose() → void: Disposes this disposable and any resources it has open.
override
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
notifyChange([T? previous, T? next]) → void: Notifies the streams about a new value (or forces the notification without equality check).
inherited
register(ObserveAware? value, {ObserveAware? replaces, bool initialNotification = true}) → ObserveAware?: Starts listening on value changes (if not already doing so).
registerStream(Stream stream, {Stream? replaces, bool initialNotification = true}) → Stream: Starts listening on value changes (if not already doing so).
toString() → String: A string representation of this object.
inherited
unregister(ObserveAware? value) → void: Stops listening on value changes.
unregisterStream(Stream? stream) → void: Stops listening on stream events.
