React-native-android - How to save an image in the Android file system and view Gallery in your phone,

Question

Is it possible to save an image in the local Android file system so that it can be viewed from the Gallery phone and in a folder?

I found this react-native-fs library , but after studying the documentation and working with the example, I'm still not sure if this is possible.
