In Nav2, the NavController held a reference to your Activity.
In Nav3, the back stack is totally decoupled from the other layers, so you don't have any of the same constraints.

Usually that kind of error means you didn't have an 'else' statement in your when statement - something the entryProvider takes care of for you (see the fallback parameter if you want to customize the default behavior for unknown keys).

FYI, Navigation3 1.0.0 depends on Compose Runtime 1.9.5 which has an important fix to a "Missed recording an endGroup" crash that Navigation3 ends up hitting more often due to its internal usage of movableContentOf() - make sure to update!

Navigation3 is really a turning point for the whole Architecture Components team as we look to work closely with the Compose team and think more holistically about what it takes to build an Android app.

There's still a lot of things we have planned for Navigation3 in our 1.1 release and beyond, where each release will be an opportunity for patterns you see in our recipes repository to "graduate" and become (optional) helpers in the library itself.

Good catch! That means it has been even longer since the last stable release, wow.
I guess you get 2 releases worth of fixes in one 😅

But I would suggest filing an issue against Navigation3: issuetracker.google.com/issues/new?c...
Maybe this would be a lot easier if there was a more structured API between an OverlayScene and NavDisplay to support overlay windows that don't know how to animate themselves out.

So the 'correct' solution is to have Popup support exit animations (which, unlike Dialog, could actually be driven by Compose animations).
As a workaround though? You do have another location to hoist composables that need to live longer than the Scene - at your rememberPopupSceneStrategy() level.

If you look at what Compose's Dialog does, it respects the window animations and animates the Dialog out when it is removed from composition. So the Scene leaves composition, but the Dialog still animates.
