2 years ago Does it work outside an isolate?

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? 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.
