Isolate Support
Description
Currently Amplify does not support running in isolates such as:
- Isolate.spawn
- workmanager
Amplify need to be configured in each isolate which has a large memory footprint and will fail when configuring native resources multiple times (ex. DataStore).
Some plugins (ex. push notifications) can only run on the main isolate due to platform limitations.
WorkManager can stop the Flutter engine which deinitializes all of our native plugins thus breaking most packages.

Steps to Reproduce
//Spawning an isolate final jsonData = await Isolate.run(_someFuction);
//WorkManager Example @pragma('vm:entry-point') void callbackDispatcher() { Workmanager().executeTask((task, inputData) async { safePrint("executeTask"); return Future.value(true); }); }
void main() async { WidgetsFlutterBinding.ensureInitialized();
final auth = AmplifyAuthCognito(); final pushPlugin = AmplifyPushNotificationsPinpoint(); await Amplify.addPlugins([auth, pushPlugin]); await Amplify.configure(amplifyconfig);
Amplify.Notifications.Push.onTokenReceived.listen((event) { safePrint("onTokenReceived: $event"); });
Workmanager().initialize(callbackDispatcher, isInDebugMode: true); Workmanager().registerOneOffTask("test", "test");
runApp(const MyApp()); }
