Calling configure() method crashes the app on iOS device

[DDavidPrime]

While testing on iOS on simulator, everything was working fine until I tried running my app on a real device. I noticed that it was crashing and while debugging I discovered that it was crashing on this line:

flutterVoipPushNotification.configure( onMessage: onMessage, onResume: onResume);

I checked and I was calling the requestNotificationPermissions() method successfully. After some additional debugging (stepping inside the configure() method), the app was breaking at _channel.invokeMethod<void>('configure'); which is a call to the native code (which would make sense since it is not crashing on the simulator).

Any idea why it would be crashing or any help ?

Additional info:
Device: iPhone 7
Simulator: iPhone 12 Pro Max
Simulator and device version: iOS 14.2.

Have you enabled voip background modes in your ios/Runner/info.plist file?
