Is there anything like

viewPager

in compose beta, or should we still go for interoperability for something like that for now?

There is no direct viewpager component but you can easily make one. I recommend you try study compose sample apps like Jetnews etc . I am sure there must be an implementation of it

I'd follow this one. A good view pager isn't necessarily an easy thing to make. https://github.com/chrisbanes/accompanist/pull/209

I meant easy in regards to complexity of view system
