StateBloc<T> class

A class that holds a single state value accessible synchronously using StateBloc.value, as a Future using StateBloc.current or as a stream using StateBloc.stream and StateBloc.changes for a stream of the current and previous value.

Constructors

changes → Stream<StateChangeTuple<T?>>: Returns a stream that emits all of changes to the value of the StateBloc as a StateChangeTuple containing the StateChangeTuple.current and StateChangeTuple.previous value.
no setter
current → Future<T?>: A Future that waits for a value to be added to the StateBloc. Completes with the current value if the StateBloc already has a value.
no setter
hashCode → int: The hash code for this object.
no setterinherited
isClosed → bool: Returns whether the StateBloc's stream controller is able to receive new events or has been closed.
no setter
next → Future<T?>: A Future that waits for the next value to be added to the StateBloc.
no setter
nonNullStream → Stream<T>: Returns a stream that emits all of the non-null updates to the value held by the StateBloc, starting with the current value.
no setter
previousValue → T?: The previous value of the StateBloc.
no setter
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
stream → Stream<T?>: Returns a stream that emits all of the updates to the value held by the StateBloc, starting with the current value.
no setter
value ↔ T?: The current value of the StateBloc.
getter/setter pair

add(T? value) → void: Updates the current value of the StateBloc to the provided value.
close() → dynamic: Closes the StreamController for the StateBloc. No further items will be emitted by the StateBloc Stream or Future interfaces.
dispose() → dynamic: Disposes all resources held by the StateBloc.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.

setValue(void updateFn(T? currentValue)) → void: Executes the provided updateFn and then re-emits the updated value on the stream. Consider the following example where the current value is updated:
toString() → String: A string representation of this object.
