### Your question

The persistent notification is now showing on Android 16. It's working fine on Android 12 & 15. The app already has all necessary permissions.
Am I missing something?

### Version

14.0.2

Start with the Android guidance in geolocator/README.md and reproduce the persistent-notification behavior using geolocator 14.0.2 on Android 16, comparing it with Android 12 and 15. Check whether the documented permissions and configuration are sufficient; done means identifying the missing requirement or producing an actionable plugin fix with verified Android 16 behavior.
