### Please check the following before submitting a new issue.

- [X] I have searched the [existing issues](https://github.com/baseflow/flutter-geolocator/issues).
- [x] I have carefully [read the documentation](https://github.com/Baseflow/flutter-geolocator/blob/main/geolocator/README.md) and verified I have added the required platform specific configuration.

### Please select affected platform(s)

- [ ] Android
- [X] iOS

### Steps to reproduce

1. Enable location on device and in application.
2. Execute: `final permission = await Geolocator.requestPermission();`
3. "Allow to use location" popup should appear:
4. Lock the phone.
5. Unlock the phone.

### Expected results

- Bring back "Allow to use location" when going back to application.
OR
- Complete the Future with proper state.

### Actual results

1. "Allow to use location" is gone.
2. `final permission = await Geolocator.requestPermission();` is waiting forever.
3. Another call to this method results in exception:
```
Unhandled Exception: A request for location permissions is already running, please wait for it to complete before doing another request.
```
