SingleCubit<Value, Filter, ExtraData> class

It allows you to wait for the fetch of a value, if it is not successful it notifies the failure, if the value does not exist it notifies the non-existence otherwise it notifies the new value.

Constructors

SingleCubit({ValueFetcher<Value, Filter>? fetcher, Filter? initialFilter, bool canWaitFirstFilter = false, bool filterEquals(Filter? e1, Filter? e2)?, Duration? filterDebounceTime, ExtraData? initialExtraData})
Create the cubit that is waiting to receive a value, the initial state is ObjectCubitUpdating
SingleCubit.empty({ValueFetcher<Value, Filter>? fetcher, Filter? initialFilter, bool canWaitFirstFilter = false, bool filterEquals(Filter? e1, Filter? e2)?, Duration? filterDebounceTime, ExtraData? initialExtraData})
Create the cubit without a value, the initial state is ObjectCubitUpdated
SingleCubit.seed({ValueFetcher<Value, Filter>? fetcher, Filter? initialFilter, bool canWaitFirstFilter = false, bool filterEquals(Filter? e1, Filter? e2)?, Duration? filterDebounceTime, ExtraData? initialExtraData, required Value initialValue})
Create the cubit with an initial value, the initial state is ObjectCubitUpdated

Methods

addError(Object error, [StackTrace? stackTrace]) → void
Reports an error which triggers onError with an optional StackTrace.
inherited
applyFetcher({required ValueFetcher<Value, Filter> fetcher}) → void
applyFilter({required Filter? filter}) → void
inherited
applyFilterChanges({required Stream<Filter?> onFilterChanges}) → void
inherited
applyFilterCubit({required ObjectCubit<Filter?, Object> filterCubit}) → void
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(ObjectCubitState<Value, ExtraData> state) → void
Updates the state to the provided state. emit does nothing if the instance has been closed or if the state being emitted is equal to the current state.
inherited
fetch() → void
listen(void onData(ObjectCubitState<Value, ExtraData>)?, {Function? onError, void onDone()?, bool? cancelOnError}) → StreamSubscription<ObjectCubitState<Value, ExtraData>>
Adds a subscription to the Stream<State>. Returns a StreamSubscription which handles events from the Stream<State> using the provided onData, onError and onDone handlers.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
onChange(Change<ObjectCubitState<Value, ExtraData>> 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
reset() → void
override
toString() → String
A string representation of this object.

updateExtraData(ExtraData extraData) → void

Operators

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