Saving data to Firestore not working ONLY ON PRODUCTION
Hi,
I'm using the FlutterIsolates to save mass data to my Firestore server. When I test it running from Android Studio, it works perfectly. But, when I send it to Internal Test, the data never reaches the firestore server.
void saveStall(String payload) async {
final mainIsolatePort = ReceivePort();
final saveIsolate = await FlutterIsolate.spawn(
saveStallToFirestore, mainIsolatePort.sendPort);
mainIsolatePort.listen(
(messageFromSaveIsolate) {
if (messageFromSaveIsolate is SendPort) {
messageFromSaveIsolate.send(payload);
}
if (messageFromSaveIsolate is String) {
if (messageFromSaveIsolate == 'ok') {
saveIsolate.kill();
mainIsolatePort.close();
} else {
//TODO: treat error
}
}
},
onDone: () {},
onError: (e) {
saveIsolate.kill();
mainIsolatePort.close();
});
}
saveStallToFirestore(SendPort mainIsolatePort) async {
final saveStallToFirebaseIsolatePort = ReceivePort();
try {
mainIsolatePort.send(saveStallToFirebaseIsolatePort.sendPort);
saveStallToFirebaseIsolatePort.listen((messageFromMainIsolate) async {
if (messageFromMainIsolate is String) {
var json = jsonDecode(messageFromMainIsolate, reviver: dateDecoder);
WidgetsFlutterBinding.ensureInitialized();
await Firebase.initializeApp();
StallRepository.instance.update(
farmId: json['farmId'], id: json['id'], json: json['stall']);
List<dynamic> ovines =
json['ovines'].map((e) => Ovine.fromJson(e['id'], e)).toList();
for (Ovine o in ovines) {
OvineRepository.instance
.update(farmId: json['farmId'], id: o.id, json: o.toJson());
}
mainIsolatePort.send('ok');
}
});
} catch (err) {
mainIsolatePort.send('error');
}
}
//Method called by OvineRepository.instance.update in the above snippet
Future<void>? update(
{required String farmId,
required String id,
required Map<String, dynamic> json,
SendPort? messenger}) {
try {
var result = FirebaseFirestore.instance
.collection(farmsCollectionKey)
.doc(farmId)
.collection(ovinesCollectionKey)
.doc(id)
.update(json);
if (messenger != null) {
messenger.send('ok');
}
return result;
} catch (e) {
Get.snackbar(
'error'.tr,
e.toString(),
snackPosition: SnackPosition.TOP,
backgroundColor: Colors.white,
colorText: Colors.black,
);
return null;
}
}
Any ideas what I may be doing wrong? Thanks in advance.
Does it work outside an isolate?

@nmfisher yes, they work outside the isolate in production. Inside only when debbuging

Have you tried calling await Firebase.initializeApp(); in the main isolate before trying to save anything in the spawned isolate?
@nmfisher thanks for the suggestion. I tried now and received the following error:
Unhandled Exception: [core/no-app] No Firebase App '[DEFAULT]' has been created - call Firebase.initializeApp()
Do you have authentication set up on your Firebase database, and if so, how/where in the app are you authenticating?

Yes, I have authentication set up. When the user opens the app a listener checks the firebase credentials and if they are not valid, routes the user to the auth screen. It does not happen inside an isolate though
Sorry I did reply to this via e-mail but it looks like GitHub didn't put it through.
Can you try manually authenticating to Firebase inside the same isolate before saving the data?
Hi @nmfisher. That happened to me too ;D
I'll test that as soon as I can. But I don't see this working in a real scenario, since I have authentication via phone number, email and social networks.
Hey @nmfisher . I didn't have a change to test your latest suggestion. But, as I mentioned, it would not be a viable solution in my case. The funny thing is that I used flutter_isolate for a few weeks in production working perfectly. And now it only works in debug.
My solution was to remodel my database to have smaller objects.
Thanks for the attention and help.
That was not a solution, it was a debugging step to check whether authenticating to a Firebase instance outside an isolate also authenticates to the instance inside the isolate (I suspect it doesn't). I will leave this open so if anyone has a similar problem in future, please try this first and report here.
Try this PR, it might fix it. https://github.com/rmawatson/flutter_isolate/pull/118
I have the same problem. The app is working in debug model but not in release mode. Could you please publish a new version with the proposed fix?
Yes, I have authentication set up. When the user opens the app a listener checks the firebase credentials and if they are not valid, routes the user to the auth screen.

@eduardothiesen we've recently published fixes for issues running Flutter > 3.3 in release mode, can you advise if these have fixed your issue?
