UnpackAssistantBloc class Null safety

UnpackAssistantBloc is responsible for helping the user importing or unpacking their exported archive from other apps. The assistant takes the user through the following steps to help them import their data:

  1. Select the app or services.
  2. Select the archive file.
  3. Select data from archive to import.
  4. Process the archive.
  5. Complete the import.

Constraints:

  1. Run one at a time.
  2. The app must be in the foreground.

Properties

hashCode → int
The hash code for this object.
read-onlyinherited
isClosed → bool
Whether the bloc is closed.
read-onlyinherited
runtimeType → Type
A representation of the runtime type of the object.
read-onlyinherited
state → UnpackAssistantState
The current state.
read-onlyinherited
stream → Stream<UnpackAssistantState>
The current stream of states.

Methods

add(UnpackAssistantEvent event) → void
Notifies the Bloc of a new event which triggers all corresponding EventHandler instances.
inherited
addError(Object error, [StackTrace? stackTrace]) → void
Reports an error which triggers onError with an optional StackTrace.
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.
inherited
emit(UnpackAssistantState state) → void
emit is only for internal use and should never be called directly outside of tests. The Emitter instance provided to each EventHandler should be used instead.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed.
inherited
on<E extends Event>(EventHandler<E, UnpackAssistantState> 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<UnpackAssistantState> 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.
inherited
onError(Object error, StackTrace stackTrace) → void
Called whenever an error occurs and notifies BlocObserver.onError.
override
onEvent(UnpackAssistantEvent event) → void
Called whenever an event is added to the Bloc. A great spot to add logging/analytics at the individual Bloc level.
override
onTransition(Transition<UnpackAssistantEvent, UnpackAssistantState> 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.
inherited
toString() → String
A string representation of this object.

Operators

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