Hello, I have a nav controller that I want to be disposable in a sense. I have a DialogFragment that is a bit complex, but not complex enough for an Activity. A NavController would be a perfect fit for handling some of its subviews. However, a it seems an instance of the graph is stored somehow because when I inflate the layout again, I get an exception

Not Kotlin related. But have a look at this. https://stackoverflow.com/questions/50311637/navigation-architecture-component-dialog-fragments

Ah, okay, sorry about that. I do use Kotlin to make the app though 😉
