Does MVIKotlin have a file template as well? similar like badoo here

Not currently. But I will consider this, thanks! MVIKotlin is simpler than MVICore in terms of

Store

creation. You don't need to extend any particular class. And there is no any "recommended" approach. You may create an interface + factory, or interface + impl, or just impl. There are also multiple ways of writing impls. Plus one may like passing

StoreFactory

as dependency or just create a top-level field and access it directly.
