PostBloc class Null safety

The Bloc that handles post loading and sorting.

Inheritance

Constructors

PostBloc({required PostRepository repository, String? subreddit})
Create a new PostBloc.

Properties

hashCode → int
The hash code for this object. [...]
read-only, inherited
isClosed → bool
Whether the bloc is closed. [...]
read-only, inherited
repository → PostRepository
The repository used to retrieve posts.
final
runtimeType → Type
A representation of the runtime type of the object.
read-only, inherited
state → PostState
The current state.

stream → Stream<PostState>
The current state stream.
read-only, inherited
subreddit → String?
The specific subreddit to retrieve post for. If this is null, search for the homepage.

Methods

add(PostEvent event) → void
Notifies the Bloc of a new event which triggers all corresponding EventHandler instances. If close has already been called, any subsequent calls to add will be ignored and will not result in any subsequent state changes.
inherited
addError(Object error, [StackTrace? stackTrace]) → void
Reports an error which triggers onError with an optional StackTrace.
@mustCallSuper, inherited
close() → Future<void>
Closes the event and state Streams. This method should be called when a Bloc is no longer needed. Once close is called, events that are added will not be processed. In addition, if close is called while events are still being processed, the Bloc will finish processing the pending events.
@mustCallSuper, inherited
emit(PostState state) → void
emit should never be used outside of tests. [...]
@visibleForTesting, inherited
listen(void onData(PostState)?, {Function? onError, void onDone()?, bool? cancelOnError}) → StreamSubscription<PostState>
Adds a subscription to the Stream<State>. Returns a StreamSubscription which handles events from the Stream<State> using the provided onData, onError and onDone handlers.
@Deprecated('Use stream.listen instead. Will be removed in v8.0.0'), inherited
mapEventToState(PostEvent event) → Stream<PostState>
@Deprecated - Use on instead. Will be removed in v8.0.0 [...]
@Deprecated('Use on<Event> instead. Will be removed in v8.0.0'), inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed. [...]
inherited
on<E extends Event>(EventHandler<E, PostState> handler, {EventTransformer<E>? transformer}) → void
Register event handler for an event of type E. There should only ever be one event handler per event type E. [...]
inherited
onChange(Change<PostState> change) → void
Called whenever a change occurs with the given change. A change occurs when a new state is emitted. onChange is called before the state of the cubit is updated. onChange is a great spot to add logging/analytics for a specific cubit. [...]
@mustCallSuper, inherited
onError(Object error, StackTrace stackTrace) → void
Called whenever an error occurs and notifies BlocObserver.onError. [...]
@mustCallSuper, @protected, inherited
onEvent(PostEvent event) → void
Called whenever an event is added to the Bloc. A great spot to add logging/analytics at the individual Bloc level. [...]
@mustCallSuper, @protected, inherited
onTransition(Transition<PostEvent, PostState> transition) → void
Called whenever a transition occurs with the given transition. A transition occurs when a new event is added and a new state is emitted from a corresponding EventHandler. executed. onTransition is called before a Bloc's state has been updated. A great spot to add logging/analytics at the individual Bloc level. [...]
@mustCallSuper, @protected, inherited
toString() → String
A string representation of this object. [...]
inherited
transformEvents(Stream<PostEvent> events, TransitionFunction<PostEvent, PostState> transitionFn) → Stream<Transition<PostEvent, PostState>>
@Deprecated - Use on<Event> with an EventTransformer instead. Will be removed in v8.0.0 [...]
@Deprecated('Use `on<Event>` with an `EventTransformer` instead. ' 'Will be removed in v8.0.0'), inherited
transformTransitions(Stream<Transition<PostEvent, PostState>> transitions) → Stream<Transition<PostEvent, PostState>>
@Deprecated - Override Stream<State> get stream instead. Will be removed in v8.0.0 [...]
@Deprecated('Override `Stream<State> get stream` instead. Will be removed in v8.0.0'), inherited

Operators

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