FormBlocObserver class

FormBlocObserver hide events and transitionsof any FieldBloc or FormBloc from the child.

But the child retains the behavior of the current BlocObserver.

You can customize using:

Example: final blocObserver = FormBlocObserver( child: MyBlocObserver(), ); BlocOverrides.runZoned(_run, blocObserver: blocObserver)

Constructors

FormBlocObserver({bool notifyOnFieldBlocCreate = false, bool notifyOnFieldBlocChange = false, bool notifyOnFieldBlocError = true, bool notifyOnFieldBlocClose = false, bool notifyOnFormBlocCreate = false, bool notifyOnFormBlocChange = false, bool notifyOnFormBlocError = true, bool notifyOnFormBlocClose = false, required BlocObserver child})

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.
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.
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.
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.
onEvent(Bloc bloc, Object? event) → void
Called whenever an event is added to any bloc with the given bloc and event.
inherited
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.
inherited
toString() → String
A string representation of this object.

Operators

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