Constructors
-
StreamSubscriptionNotifier(StreamSubscription<
T> _sub, {bool ignoreError = false, bool cancelOnDispose = true, bool cancelOnError = false, bool cancelOnDone = false}) - A StreamSubscriptionNotifier exposes a StreamSubscription to a ChangeNotifier.
-
StreamSubscriptionNotifier.stream(Stream<
T> stream, {bool ignoreError = false, bool cancelOnDispose = true, bool cancelOnError = false, bool cancelOnDone = false}) -
Register a StreamSubscription on
stream
and instantiate a StreamSubscriptionNotifier from the registered StreamSubscription.factory
Properties
- cancelOnDispose → bool
-
True
if the supplied StreamSubscription should get called once StreamSubscriptionNotifier.dispose gets called.final - cancelOnDone → bool
-
True
if the supplied StreamSubscription should get called once it is done.final - cancelOnError → bool
-
True
if the supplied StreamSubscription should get called once an error gets emitted.final - hadError → bool
-
True
if the underlying StreamSubscription emitted an error.no setteroverride - hashCode → int
-
The hash code for this object.
no setterinherited
- hasListeners → bool
-
Whether any listeners are currently registered.
no setterinherited
- hasValue → bool
-
If
true
then value can successfully be read.no setteroverride - ignoreError → bool
-
True
if this StreamSubscriptionNotifier should ignore it if the underlying StreamSubscription emits an error.final -
isCancelled
→ AdvancedValueListenable<
bool> -
True
if the underlying StreamSubscription got cancelled by this StreamSubscriptionNotifier.no setteroverride -
isDone
→ AdvancedValueListenable<
bool> -
Whether the underlying StreamSubscription is done or not.
no setteroverride
-
onError
→ EmptyValueListenable<
StreamError> -
Get the most recent
StreamError
the StreamSubscription emitted.no setteroverride - runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- value ↔ T
-
The current value of the object. When the value changes, the callbacks
registered with addListener will be invoked.

Methods
-
addListener(
VoidCallback listener) → void -
Register a closure to be called when the object changes.
inherited
-
addValueListener(
ValueCallback< T> listener) → void -
inherited
-
cancel(
) → Future< bool> - Cancel the underlying StreamSubscription.
-
dispose(
) → Future< 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).
override
-
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
-
removeValueListener(
ValueCallback< T> listener) → void -
inherited
-
toString(
) → String -
A string representation of this object.
override
Operators
-
operator ==(
Object other) → bool -
The equality operator.
