DVMutableLifecycleSignal<T> class

The framework-facing half of a lifecycle signal.

Kept separate from DVLifecycleSignal so that handing a signal to application code hands over no way to drive it.

Properties

changes → Stream<T>
Emits on every transition. Does not replay the current value; read value for that.
no setteroverride

The hash code for this object.
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
value → T
The current state.
no setteroverride

Methods

dispose() → Future<void>
listen(FutureOr<void> onState(T state)) → StreamSubscription<T>
Observes transitions. Returns a subscription the caller can cancel.
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
read() → T
The current state. Provided so reads look the same as elsewhere in Dartvel, where signals are read with .read().
override
set(T next) → void
Advances the state. Re-emitting the same state is a no-op, so observers only ever see genuine transitions.
toString() → String
A string representation of this object.
inherited

Operators

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