Is there any good reference for feature - level - modularization, including the handling of navigation

Modularization by features: https://proandroiddev.com/modularization-of-android-applications-in-2021-a79a590d5e5b But the navigation is not covered in the articles. Probably, you would want to provide a factory of fragments from a feature module and use it in an external (to the feature module) navigation system.

I like this talk ->

good one, Thanks
