onError method Null safety

void onError(
  1. Object error,
  2. StackTrace stackTrace
)
override

Called whenever an error occurs and notifies BlocObserver.onError.

Note: super.onError should always be called last.

@override
void onError(Object error, StackTrace stackTrace) {
  // Custom onError logic goes here

  // Always call super.onError with the current error and stackTrace
  super.onError(error, stackTrace);
}

Implementation

@override
void onError(error, stackTrace) {
  // TODO: implement analytics here
  log("$runtimeType - error", error: error, stackTrace: stackTrace);
  super.onError(error, stackTrace);
}
