Properties

addEvent → dynamic Function(BlocEvent)
Notifies the BloC of a new event which triggers mapEventToState. If dispose has already been called, any calls to dispatchEvent will be ignored and will not result in any state changes.

blocState ↔ MatexCountryBlocState
The current BloC's state.
getter/setter pairinherited
cancelableOperations ↔ List<CancelableOperation>
The list of cancelable operations.

closed ↔ bool
Whether the BloC is closed.

currentState → MatexCountryBlocState
The current BloC's state.
no setterinherited
dispatchState → dynamic Function(MatexCountryBlocState)
Notifies the BloC of a new state which triggers onData.

Methods

canClose() → bool
Whether the BloC can be closed. Override this method to prevent the BloC from closing.
inherited
close() → void
Closes the BloC. This method should be called when the BloC is no longer needed.
inherited
debounce(BlocDebounceCallback<BlocEvent> function, {Duration delay = const Duration(milliseconds: 300)}) → BlocDebounceCallback<BlocEvent>
Creates a debounced function that only invokes function after a delay.
inherited
debounceEvent(BlocEventCallback<MatexCountryBlocEvent> function, {Duration delay = const Duration(milliseconds: 300)}) → BlocEventCallback<MatexCountryBlocEvent>
Debounces an event. The function will not be invoked until delay.
inherited
findOne({required bool filter(MatexCountryMetadata)}) → Future<MatexCountryMetadata?>
Finds one country metadata based on the provided filter function.
findOneByCountryCode(String countryCode) → Future<MatexCountryMetadata?>
Fetches metadata for a country with the given country code.
get(String key) → Future<MatexCountryMetadata?>
Retrieves country metadata by key.
getEventForState(MatexCountryBlocState state) → MatexCountryBlocEvent?
Returns the event related to the given state.
inherited
getInitialState() → MatexCountryBlocState
Tries to retreive the initial BloC's state.
inherited
handleInitEvent(String? jsonData) → Stream<MatexCountryBlocState>
Processes the initialization event. It fetches country metadata and triggers the initialized event.
handleInitializedEvent(List<MatexCountryMetadata>? countries) → Stream<MatexCountryBlocState>
Handles the initialized event by setting the provided country metadata countries to the state.
handleInternalError(dynamic error, StackTrace stackTrace) → void
Handles internal errors.
inherited
initState() → MatexCountryBlocState
Optional callback method to initialize the BloC's state.
inherited
mapEventToState(MatexCountryBlocEvent event) → Stream<MatexCountryBlocState>
Maps incoming MatexCountryBlocEvent to corresponding MatexCountryBlocState. Processes events and updates states accordingly.
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
performCancellableAsyncOperation<T>(Future<T> opreation) → Future<T?>
Performs an asynchronous operation and cancels it if the BloC is closed.
inherited
resetBloc() → void
inherited
sampleEvent(BlocEventCallback<MatexCountryBlocEvent> function, {Duration delay = const Duration(milliseconds: 300)}) → BlocEventCallback<MatexCountryBlocEvent>
inherited
setState(MatexCountryBlocState nextState) → void
Set the BloC state.
inherited
shouldProcessEventInOrder() → bool
Determines whether a bloc ensures all events are processed in the order in which they are received.
inherited
throttle(BlocThrottleCallback<BlocEvent> function, {Duration duration = const Duration(milliseconds: 300)}) → BlocThrottleCallback<BlocEvent>
Creates a throttled function that only invokes function at most once per every duration.
inherited
throttleEvent(BlocEventCallback<MatexCountryBlocEvent> function, {Duration duration = const Duration(milliseconds: 300)}) → BlocEventCallback<MatexCountryBlocEvent>
Throttles an event. The event will be ignored if it is dispatched within the specified duration. The last event will be dispatched after the duration has passed.
inherited
toString() → String
A string representation of this object.
inherited
transformError(dynamic error, StackTrace stackTrace) → BlocError?
Transforms the error before it is emitted.
inherited
updateEventStateHistory(MatexCountryBlocEvent event, MatexCountryBlocState nextState) → void
Updates the event-state history. The event-state history is used to determine the event related to a given state.
