Description

I've read closed issues but none of them answered what is solution / workaround. Especially quoting:

#11548 (comment)

For me FirebaseMessaging.instance.getAPNSToken(); always returns null and I am using a physical device. Is there a fix for that?

On iOS 18.x real device everything works.
On iOS 15.6 real device I am getting

APNS token has not been set yet. Please ensure the APNS token is available by calling `getAPNSToken()`

even after calling getAPNSToken(). This method returns immediately with null.

Reproducing the issue

Tried to call _fcmInstance.getToken() on iOS 15.6

Hi @petrnymsa, please make sure you're using the latest version of firebase_messaging. Also, check out this comment. It might be helpful.

Hi @petrnymsa! Please make sure your aps-environment is correctly applied in your build settings. If everything is configured properly, you should see aps-environment: production in the your TestFlight last version -> Build Metadata -> Bottom section.

I've checked metadata in TestFlight and we have production aps-environment set

Thanks for confirming the aps-environment setting. Since the configuration seems correct, could you try using FirebaseMessaging.instance.getToken() instead of getAPNSToken()? This might help resolve the issue.

Also, please double-check that you’ve properly initialized Firebase in your app with:

await Firebase.initializeApp(
  options: DefaultFirebaseOptions.currentPlatform,
);

If the issue persists, please try reproducing the issue using the latest commit from the firebase_messaging example in the official
FlutterFire Firebase Messaging Example

Let me know if this helps or if you encounter any further issues!

We are definitely calling getToken(). As stated in different issues we added call to getAPNSToken() before calling getToken().

Firebase is definitely initialized.

I have the same error on a iPhone SE iOS 15.5

Has this only been reproducible on a physical device? Have you been able to do it through simulator?
