Methods

noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
onChange(BlocBase bloc, Change change) → void
Called whenever a Change occurs in any bloc A change occurs when a new state is emitted. onChange is called before a bloc's state has been updated.
override
onClose(BlocBase bloc) → void
Called whenever a Bloc is closed. onClose is called just before the Bloc is closed and indicates that the particular instance will no longer emit new states.
override
onCreate(BlocBase bloc) → void
Called whenever a Bloc is instantiated. In many cases, a cubit may be lazily instantiated and onCreate can be used to observe exactly when the cubit instance is created.
override
onDone(Bloc bloc, Object? event, [Object? error, StackTrace? stackTrace]) → void
Called whenever an event handler for a specific bloc has completed. This may include an error and stackTrace if an uncaught exception occurred within the event handler.
inherited
onError(BlocBase bloc, Object error, StackTrace stackTrace) → void
Called whenever an error is thrown in any Bloc or Cubit. The stackTrace argument may be StackTrace.empty if an error was received without a stack trace.
override
onEvent(Bloc bloc, Object? event) → void
Called whenever an event is added to any bloc with the given bloc and event.
override
onTransition(Bloc bloc, Transition transition) → void
Called whenever a transition occurs in any bloc with the given bloc and transition. A transition occurs when a new event is added and a new state is emitted from a corresponding EventHandler. onTransition is called before a bloc's state has been updated.
override
toString() → String
A string representation of this object.
