I'm experiencing an issue while using navigation-compose. I have a very simple setup. HomePage composable receives a HomeViewModel and a HomeState object (caller passes state.value ) as its arguments.

HomePage also hosts a NavHost which includes 2 different routes(SettingsPage , ProfilePage) When I pass a field from HomeState like homeState.username to one of the composables defined in NavHost, it does not work. State changes do not reflect on children pages of HomePage .

However, carrying homeViewModel and homeState directly into HomePage composable, fixes this issue.

Can you post this code?

I can share the project with direct link to where this is happening but I can also try to build a minimal example which reproduces the said issue. I'm reluctant to share the original project because it might be difficult to navigate through.

Ok. I suspect something like a stale lambda capture, but I'd like to see if there's something about the navigation-compose API shape that might lead one to it.

What do you mean by stale lambda? It kinda reminded me of another bug that I experienced but felt like I might have been doing something wrong.

the difference between App1 and App2 should be enough to understand what is going wrong

Should I file a bug for this?

Yes, definitely file an issue against Compose
