How do I exit `androidx.navigation`'s navGraph-scoped viewmodel scope so that those viewmodels can be destroyed, and then reconstructed when I re-enter the navGraph's scope? Right now, I am calling (context as Activity).finish() inside my fragment, but that doesn't seem to be right.

That automatically happens when you pop the last destination that is the part of that graph off the back stack

If your project is SAA, why not?

I can't seem to popBackStack into the calling activity(that is not part of the nav_graph). This is how I start the activity that inflates the navGraph

startActivity(Intent(applicationContext, MainActivity::class.java))
finish()

[Ian Lake]

That seems like an entirely different question than your original question?

[Justin Xu]

Well yes, this is my result after trying your solution

[Justin Xu]

I'm not sure if I'm inflating/exiting the navgraph correctly now

Sounds like a bit of an XY Problem kind of situation: https://xyproblem.info/

[Ian Lake]

It isn't clear how 'when I re-enter the navGraph's scope' was tied to you having multiple activities

[Ian Lake]

But yes, the documentation does specifically call out when you manually pop the last destination on your back stack by returning false - that's when you need to manually finish your activity: https://developer.android.com/guide/navigation/navigation-navigate#back-stack

But if you're in those kind of cases, you're probably a bit far off the beaten path
