-
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

Methods
-
addError(
Object error, [StackTrace? stackTrace]) → void -
Reports an
error
which triggersonError
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 providedstate
.emit
does nothing if the instance has been closed or if thestate
being emitted is equal to the currentstate
.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 theStream<State>
using the providedonData
,onError
andonDone
handlers.inherited -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
onChange(
Change< AsyncQueryResult< change) → voidT> > -
Called whenever a
change
occurs with the givenchange
. Achange
occurs when a newstate
is emitted.onChange
is called before thestate
of thecubit
is updated.onChange
is a great spot to add logging/analytics for a specificcubit
.inherited -
onError(
Object error, StackTrace stackTrace) → void -
Called whenever an
error
occurs and notifiesBlocObserver.onError
.inherited -
toString(
) → String -
A string representation of this object.
inherited
-
updateWith(
Future< QueryResult< future) → Future<T> >QueryResult< T> > - Update self with future QueryResult
Operators
-
operator ==(
Object other) → bool -
The equality operator.
