I’m trying to make a background location tracking application in Flutter. So I create an isolate for running background service. its working well if I store location data in local file system from isolate. but when I connect Firebase for sending data from isolate it gives the following error:
E/flutter (10142): [ERROR:flutter/lib/ui/ui_dart_state.cc(157)] Unhandled Exception: MissingPluginException(No implementation found for method DocumentReference#setData on channel plugins.flutter.io/cloud_firestore) E/flutter (10142): #0 MethodChannel._invokeMethod (package:flutter/src/services/platform_channel.dart:154:7) E/flutter (10142): <asynchronous suspension> E/flutter (10142): #1 MethodChannel.invokeMethod (package:flutter/src/services/platform_channel.dart:329:12) E/flutter (10142): #2 MethodChannelDocumentReference.setData (package:cloud_firestore_platform_interface/src/method_channel/method_channel_document_reference.dart:28:43) E/flutter (10142): #3 DocumentReference.setData (package:cloud_firestore/src/document_reference.dart:48:22) E/flutter (10142): #4 LocationServiceRepository.callback (package:alertcat/backLocation/location_service_repository.dart:61:15) E/flutter (10142): #5 LocationCallbackHandler.callback (package:alertcat/backLocation/location_callback_handler.dart:23:40) E/flutter (10142): #6 callbackDispatcher.<anonymous closure> (package:background_locator/callback_dispatcher.dart:22:15) E/flutter (10142): #7 MethodChannel._handleAsMethodCall (package:flutter/src/services/platform_channel.dart:409:55) E/flutter (10142): #8 MethodChannel.setMethodCallHandler.<anonymous closure> (package:flutter/src/services/platform_channel.dart:377:54) E/flutter (10142): #9 _DefaultBinaryMessenger.handlePlatformMessage (package:flutter/src/services/binding.dart:199:33) E/flutter (10142): #10 _invoke3.<anonymous closure> (dart:ui/hooks.dart:290:15) E/flutter (10142): #11 _rootRun (dart:async/zone.dart:1184:13) E/flutter (10142): #12 _CustomZone.run (dart:async/zone.dart:1077:19) E/flutter (10142): #13 _CustomZone.runGuarded (dart:async/zone.dart:979:7) E/flutter (10142): #14 _invoke3 (dart:ui/hooks.dart:289:10) E/flutter (10142): #15 _dispatchPlatformMessage (dart:ui/hooks.dart:164:5)
But Firebase functioning properly from outside of the isolate. What can I do to resolve this?
The main problem was an internal dependency, there was another third party package that is somehow in conflict with the firestore package,
to solve this issue, I wrote native code for the other package, now it works fine
