#### As a **convenience** this library provides methods to check and request location and external read/write permissions
```dart
// returns true/false asynchronously
bool a = await Nearby().checkLocationPermissions()
bool a = await Nearby().checkLocationPermissions();
// asks for permission only if its not given
Nearby().askLocationPermission()
// returns true/false if the location permission is granted on/off resp.
bool b = Nearby().askLocationPermission();
// OPTIONAL: if you need to transfer files and rename it on device
bool b = Nearby().checkExternalStoragePermission()
bool b = Nearby().checkExternalStoragePermission();
// asks for READ + WRTIE EXTERNAL STORAGE permission only if its not given
Nearby().askExternalStoragePermission()
Nearby().askExternalStoragePermission() ;
Nearby().askLocationAndExternalStoragePermission() // for all permissions in one go..
Nearby().askLocationAndExternalStoragePermission(); // for all permissions in one go..
