isClosed → bool
Whether the bloc is closed.
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited

Methods

addError(Object error, [StackTrace? stackTrace]) → void
Reports an error which triggers onError with an optional StackTrace.
inherited
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.
inherited
emit(T state) → void
Updates the state to the provided state. emit does nothing if the state being emitted is equal to the current state.
inherited
erase() → void

Available on SingleValueCubit<String>, provided by the SingleValueStringCubitExtension extension

clears the current state of a cubit
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
observe() → Stream<T>

Available on BlocBase<T>, provided by the BlocExtensions extension

let you observe the state of a bloc or cubit with immediate emission of current state works similar to BehaviorSubject observation
onChange(Change<T> 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.
inherited
set(T value) → void
sets the value of a cubit
toggle() → void

Available on SingleValueCubit<bool>, provided by the SingleValueBoolCubitExtension extension

toggles the current state of a cubit
toString() → String
A string representation of this object.

The equality operator.
