Post-install Steps

Add the appropriate keys to your Info.plist,

If you are allowing user to select image/video from photos, add NSPhotoLibraryUsageDescription.

If you are allowing user to capture image add NSCameraUsageDescription key also.

If you are allowing user to capture video add NSCameraUsageDescription add NSMicrophoneUsageDescription key also.

Android

Note: This library does not require Manifest.permission.CAMERA, if your app declares as using this permission in manifest then you have to obtain the permission before using launchCamera.
