Manages the internet connection status, using the Connectivity library.
Recieves ConnectivityEvent and emits ConnectivityState.
Constructors
- ConnectivityBloc(Connectivity _connectivity)
Properties
- hashCode → int
-
The hash code for this object.
read-only, inherited
- isClosed → bool
-
Whether the bloc is closed.
read-only, inherited
- runtimeType → Type
-
A representation of the runtime type of the object.
read-only, inherited
- state → ConnectivityState
-
The current state.

stream
→ Stream<
ConnectivityState> -

Methods
-
add(
ConnectivityEvent event) → void -
Notifies the
Blocof a neweventwhich triggers all correspondingEventHandlerinstances.inherited -
addError(
Object error, [StackTrace? stackTrace]) → void -
Reports an
errorwhich triggers onError with an optionalStackTrace.@mustCallSuper, @protected, inherited -
close(
) → Future< void> -
Closes the
eventandstateStreams. This method should be called when aBlocis no longer needed. Once close is called,eventsthat are added will not be processed. In addition, if close is called whileeventsare still being processed, theBlocwill finish processing the pendingevents. -
emit(
ConnectivityState state) → void -
emit is only for internal use and should never be called directly
outside of tests. The
Emitterinstance provided to eachEventHandlershould be used instead.@visibleForTesting, inherited -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a non-existent method or property is accessed.
inherited
-
on<
E extends Event> (EventHandler< E, ConnectivityState> handler, {EventTransformer<E> ? transformer}) → void -
Register event handler for an event of type
E. There should only ever be one event handler per event typeE.inherited -
onChange(
Change< ConnectivityState> change) → void -
Called whenever a
changeoccurs with the givenchange. Achangeoccurs when a newstateis emitted. onChange is called before thestateof thecubitis updated. onChange is a great spot to add logging/analytics for a specificcubit.@mustCallSuper, @protected, inherited -
onError(
Object error, StackTrace stackTrace) → void -
Called whenever an
erroroccurs and notifiesBlocObserver.onError.@mustCallSuper, @protected, inherited -
onEvent(
ConnectivityEvent event) → void -
Called whenever an
eventis added to theBloc. A great spot to add logging/analytics at the individualBloclevel.@mustCallSuper, @protected, inherited -
onTransition(
Transition< ConnectivityEvent, ConnectivityState> transition) → void -
Called whenever a
transitionoccurs with the giventransition. Atransitionoccurs when a neweventis added and a new state isemittedfrom a correspondingEventHandler. executed. onTransition is called before aBloc's state has been updated. A great spot to add logging/analytics at the individualBloclevel.@mustCallSuper, @protected, inherited -
toString(
) → String -
A string representation of this object.

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