QueryCubit<T> class

Cubit holds AsyncQueryResult

Constructors

QueryCubit([AsyncQueryResult<T>? initialState])
Create new Cubit
QueryCubit.initialValue(T intialValue)
Create new Cubit with given intial value of the query InitialValueResult will be set

Properties

hashCode → int
The hash code for this object.
no setterinherited
isClosed → bool
Whether the bloc is closed.
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
state → AsyncQueryResult<T>
The current state.
no setterinherited
stream → Stream<AsyncQueryResult<T>>
The current state stream.
no setterinherited

Methods

addError(Object error, [StackTrace? stackTrace]) → void
Reports an error which triggers onError with an optional StackTrace.
inherited
captureResult(Future<T> future) → Future<QueryResult<T>>
Capture the result of a generic aync query
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(AsyncQueryResult<T> 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
listen(void onData(AsyncQueryResult<T>)?, {Function? onError, void onDone()?, bool? cancelOnError}) → StreamSubscription<AsyncQueryResult<T>>
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<AsyncQueryResult<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
toString() → String
A string representation of this object.
inherited
updateWith(Future<QueryResult<T>> future) → Future<QueryResult<T>>
Update self with future QueryResult

Operators

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