I have a hard time with trying to learn Navigation Components. In my app, I have 6 fragments.

• Four of them are swipeable by using ViewPager 2
• Fifth fragment is not implemented in ViewPager, so user can't go there by swipping
• Sixth fragment is just a host for ViewPager, since the other fragments are used by Navigation Components

I can swipe fragments for now, but whenever I try to use Navigation Components, I getting error about action/destionation. It's simply about calling for example ActionFrag1ToFrag5 from my Host Fragment

It seems like I can browse through fragments, but I can't cast any Navigation Component functions, because the fragment stays the same, it doesn't change label after swipe to another one.

Is there a way to get proper NavController from specific fragment, or it's just my poor implementation?

If Frag1, Frag2, Frag3, and Frag4 are those in the ViewPager and you want to go to Frag5.

The direction needs to be from the Frag6 that is hosting the ViewPager to the Frag5.
