Methods
-
addError(Object error, [StackTrace? stackTrace])
→ void
-
Reports an
error
which triggers onError with an optional StackTrace.
-
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.
-
emit(State 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
.
-
listen(void onData(State)?, {Function? onError, void onDone()?, bool? cancelOnError})
→ StreamSubscription<State>
-
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.
-
noSuchMethod(Invocation invocation)
→ dynamic
-
Invoked when a nonexistent method or property is accessed.
inherited
-
onChange(Change<State> 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
.
-
onError(Object error, StackTrace stackTrace)
→ void
-
Called whenever an
error
occurs and notifies BlocObserver.onError.
-
toString()
→ String
-
A string representation of this object.
