<!-- When reporting a feature, please read this complete template and fill all the questions in order to get a better response --> # Problem to solve Allowing push notification registration, in keeping with the features supported by the iOS and Android SDKs provided by Twilio. # Proposal <!-- What do you propose as a solution? Add as much information as you can! --> # More information On iOS side, to receive an APNs token, a plugin must register itself with the FlutterPluginRegistrar, and implement `didRegisterForRemoteNotificationsWithDeviceToken` to receive the token, and `didFailToRegisterForRemoteNotificationsWithError` to receive errors, prior to `UIApplication.shared.registerForRemoteNotifications` being called (permissions must also be requested). At the time of logging this issue, while the `AppDelegate`, being a `UIApplicationDelegate` can successfully (if inconsistently) receive these callbacks, the plugin itself does not. The [`flutter_apns`](https://pub.dev/packages/flutter_apns) plugin seems to be having similar [issues](https://github.com/mwaylabs/flutter-apns/issues) <!-- DO NOT CHANGE ANYTHING BELOW THIS LINE -->
