InternetCubit class

Monitors network connectivity and emits InternetState changes.

Merges the connectivity_plus adapter state stream with the internet_connection_checker_plus reachability stream, debounced at 300 ms, to produce a single reliable connectivity signal. A ToastService.showNoInternetToast is shown automatically when the device transitions from InternetConnected to InternetDisconnected.

Properties

connectivity → Connectivity
The connectivity_plus adapter used to detect the network interface type.
final
hashCode → int
The hash code for this object.
no setterinherited
internetConnection → InternetConnection
The internet_connection_checker_plus checker used to verify actual internet reachability.
final
isClosed → bool
Whether the bloc is closed.
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
state → InternetState
The current state.
no setterinherited
stream → Stream<InternetState>
The current stream of states.
no setterinherited
toastService → ToastService
The service used to show a no-internet toast when connectivity is lost.

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.
override
emit(InternetState state) → void
Updates the state to the provided state. emit does nothing if the state being emitted is equal to the current state.
inherited
initialize() → Future<void>
Performs an initial connectivity check and starts the merged event stream.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
onChange(Change<InternetState> 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
recheck() → Future<void>
Forces an immediate connectivity re-check outside the debounce window.
toString() → String
A string representation of this object.
inherited

Operators

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