While calling the subscribeToTopic method in iOS, this APNS token exception is coming. I have followed the documentation. I have used the Flutterfire configure command for configuring the Flutter project.
But this error is coming. Anyone know why this error is coming and how to resolve it?
I haven’t called the getAPNSToken() method in the code.
Is it needed to initiate this method before calling subscribeToTopic method?
Note: We are not using tokens to send notifications to particular users. We are using the topic to send notifications. So I’m not calling the getToken and getAPNSToken methods.

As per documentation an APNS token needs to be available before calling subscribeToTopic method.
So on the iOS platform, if apnsToken is not available, we have added a delay. After a delay, if we are calling getAPNSToken, it is getting a token. so we can call the subscribeToTopic method.
