 Starting with Android 10, apps are required to first obtain permission to read the device's location in the foreground, before requesting to read the location in the background as well. When requesting the 'location always' permission directly, or when requesting both permissions at the same time, the system will ignore the request. So, instead of calling only `Permission.location.request()`, make sure to first call either `Permission.location.request()` or `Permission.locationWhenInUse.request()`, and obtain permission to read the GPS. Once you obtain this permission, you can call `Permission.locationAlways.request()`. This will present the user with the option to update the settings so the location can always be read in the background. For more information, visit the [Android documentation on requesting location permissions](https://developer.android.com/training/location/permissions#request-only-foreground).

 ### Checking or requesting a permission terminates the application on iOS. What can I do?
 
 First of all make sure all that the `ios/Runner/Info.plist` file contains entries for all the permissions the application requires. If an entry is missing iOS will terminate the application as soon as the particular permission is being checked or requested.
