Methods

addError(Object error, [StackTrace? stackTrace]) → void

Reports an error which triggers onError with an optional StackTrace.

override

close() → Future<void>

Closes the instance. This method should be called when the instance is no longer needed. Once close is called, the instance can no longer be used.

override

emit(State state) → void

Updates the state to the provided state. emit does nothing if the state being emitted is equal to the current state.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

onChange(Change<State> 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.

onError(Object error, StackTrace stackTrace) → void

Called whenever an error occurs and notifies BlocObserver.onError.

toString() → String

A string representation of this object.
