[tobolski]

Please check the following before submitting a new issue.

• I have searched the existing issues.
• I have carefully read the documentation and verified I have added the required platform specific configuration.

Please select affected platform(s)

• Android
• iOS
• Linux
• macOS
• Web
• Windows

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.
