I'm using fcm and firebase\_messaging to send push notification to flutter app, and want to custom permission message when executing FirebaseMessaging().requestNotificationPermissions for ios remote notification.

Now I have permission dialog below

![Current permission dialog screenshot](https://i.stack.imgur.com/VV3gA.png)

How to custom '"" Would Like to Send You Notifications', 'Notifications may include alerts, sounds, and icon...', and 'Don't Allow/Allow'? Does anyone any idea?

and my code 

```
final FirebaseMessaging  _firebaseMessaging = FirebaseMessaging();
await _firebaseMessaging.requestNotificationPermissions(
              const IosNotificationSettings(
                sound: true, badge: true, alert: true));
await _firebaseMessaging.onIosSettingsRegistered.listen((settings) {
              debugPrint('Settings registered: $settings');
          });

```

Here's my `flutter doctor -v` result
