Steps to reproduce?
1. Update OneSignal to version 5.3.4
2. Use Flutter Version 3.29.2
3. Try to initialize OneSignal in main.dart
4. Run the project in Android Production
—- Code —-
void main() async {
WidgetsFlutterBinding.ensureInitialized();
if (Constants.isCrashlyticsEnabled) {
await Firebase.initializeApp(
options: DefaultFirebaseOptions.currentPlatform);
FlutterError.onError = FirebaseCrashlytics.instance.recordFlutterError;
}
OneSignal.initialize(Constants.onesignalAppID);
// some code that calls OneSignal.User.setLanguage()
// .... some other code
if (kDebugMode) {
OneSignal.Debug.setLogLevel(OSLogLevel.verbose);
}
// The promptForPushNotificationsWithUserResponse function will show the iOS or Android push notification prompt. We recommend removing the following code and instead using an In-App Message to prompt for notification permission
OneSignal.Notifications.requestPermission(false).then((accepted) {
Helper.talker.debug("Accepted permission: $accepted");
});
OneSignal.Notifications.addClickListener((openedResult) {
openedFromNotfication = true;
});
runApp(
ChangeNotifierProvider(
create: (context) => settingsProvider,
child: const MyApp(),
),
);
}
What did you expect to happen?
OneSignal should be initialized and working fine like in debug mode.
