-### Requesting permissions
-
-Newer API levels of Android and iOS versions are requiring explicit permissions in order the application
-to have access to the camera and to be able to save photos to the device. Once the user has granted permissions the camera module can be used.

-```
-camera.requestPermissions();
-```

-> Note: Older versions won't be affected by the usage of the requestPermissions method.
