用户在使用react-native-camera时拒绝在android上使用相机的权限时回调

Question

I'm using react-native-camera to take pictures in an android app. As soon as user reaches the camera page, the library itself asks for permission to use the device's camera on android phones (with api level >22). (Please note that I'm not manually asking for camera permission by using PermissionsAndroid api of react-native ).

Since asking for camera permission is inherent in this library, I'm expecting that it should by itself provide with appropriate callbacks when user grants or denies permission. I need to call goBack() if user denies the camera permission but could not find any appropriate callback method in their documentation wherein goBack() could be called.

You have to check permissions manually.
