This is a bottom navigation library written in kotlin language, using Google material, viewPage2, androidx, keeping the latest Android style and supporting a lot of customization.

A viewPager2 sample from android developer. In addition I add a NestedScrollRecyclerView for deal with scroll conflicts ( A same scroll direction recyclerView in viewPager2)

This application will show recent photos uploaded to the Flickr website as well as the most popular photos of the user uploads.
