My hiltViewModel calls (from the androidx.hilt.naviagtion.compose lib) returns a new instance of the retrieved viewmodel as opposed to returning the same viewmodel scoped to a navigation graph where it is first retrieved. Any ideas what I might be missing?

Got any code to show? I believe that it should give you back the same instance if that instance is still around, else it will create a new one.

Thanks @Colton Idle, I am not doing anything special:

@HiltViewModel
class MyViewModel @Inject constructor() : ViewModel

...
navigation(route = "root", startDestination="...") {
  // Expected: MyViewModel should be the same instance in the composables below
  // Actual: MyViewModel is different instances in the comoosables
  composable(...) {
     hiltViewModel<MyViewModel>
  }

  composable(...) {
     hiltViewModel<MyViewModel>
  }
}
...

@Smorg Try it like this

composable(route) {
                val viewmodel = hiltViewModel<ViewModel>(                  navController.getBackStackEntry(navigationRoute)
)
                Composable(viewmodel ,
                    navigateUp = { 
navController.navigateUp() 
}
                )
            }

Thanks @Anthony. I just read the release notes and found the same.

You need to pass into the viewmodel the route it is scoped to, which would be the navigation route "root" in this case.
