IVoidActionBloc<Event, Response, Failure> class
abstract
Void action bloc is used to automatically map action
that doesn't return any value to the states.
It works this way:
- event is added
- action is performed
- before actions is performed
in progress
state is emitted - when action is successfully performed
success
state is emitted - in case of failure
failure
state with theFailure
is emitted.
- before actions is performed
- action is performed
Constructors
-
IVoidActionBloc({required FutureArgAction<
Response, Event> action, required IVoidStateAdapter<Event, Response, Failure> stateAdapter, EventTransformer<Event> ? transformer})
Properties
- hashCode → int
-
The hash code for this object.
no setterinherited
- isClosed → bool
-
Whether the bloc is closed.
no setterinherited
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
-
state
→ IVoidActionBlocState<
Failure> -
The current state.
no setterinherited
-
stream
→ Stream<
IVoidActionBlocState< Failure> > -
The current stream of states.

Methods
-
add(
Event event) → void -
Notifies the
Bloc
of a newevent
which triggers all correspondingEventHandler
instances.inherited -
addError(
Object error, [StackTrace? stackTrace]) → void -
Reports an
error
which triggersonError
with an optional StackTrace.inherited -
close(
) → Future< void> -
Closes the
event
andstate
Streams
. This method should be called when aBloc
is no longer needed. Onceclose
is called,events
that areadd
ed will not be processed. In addition, ifclose
is called whileevents
are still being processed, theBloc
will finish processing the pendingevents
.inherited -
emit(
IVoidActionBlocState< Failure> state) → void -
emit
is only for internal use and should never be called directly outside of tests. TheEmitter
instance provided to eachEventHandler
should be used instead.inherited -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
on<
E extends Event> (EventHandler< E, IVoidActionBlocState< handler, {EventTransformer<Failure> >E> ? transformer}) → void -
Register event handler for an event of type
E
. There should only ever be one event handler per event typeE
.inherited -
onChange(
Change< IVoidActionBlocState< change) → voidFailure> > -
Called whenever a
change
occurs with the givenchange
. Achange
occurs when a newstate
is emitted.onChange
is called before thestate
of thecubit
is updated.onChange
is a great spot to add logging/analytics for a specificcubit
.inherited -
onError(
Object error, StackTrace stackTrace) → void -
Called whenever an
error
occurs and notifiesBlocObserver.onError
.inherited -
onEvent(
Event event) → void -
Called whenever an
event
isadd
ed to theBloc
. A great spot to add logging/analytics at the individualBloc
level.inherited -
onTransition(
Transition< Event, IVoidActionBlocState< transition) → voidFailure> > -
Called whenever a
transition
occurs with the giventransition
. Atransition
occurs when a newevent
is added and a new state isemitted
from a correspondingEventHandler
.inherited -
toString(
) → String -
A string representation of this object.

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