Does the viewmodel instance gets cleared upon navigating to another screen?

composable<SavedTripsRoute> { backStackEntry ->
    val viewModel: SavedTripsViewModel = koinViewModel<SavedTripsViewModel>(key = "SavedTripsNav")
}

Tried using a key, as well, but observed that when i navigate away and back to this screen, SavedTripsViewModel is recreated.

koin - 4.1.1
nav compose - 2.9.0-rc02
compose-multiplatform = "1.9.0-rc02"

happens for both ios and android.

If SavedTripsRoute is removed from the backstack then it is expected behaviour

[Karan Sharma]

SavedTripsRoute is always in the backstack.

SavedTripsRoute -> XYZScreen -> back (SavedTripsRoute) observe that VM is recreated.

How do you declare SavedTripsViewModel in Koin module?

[Karan Sharma]

viewModel {
SavedTripsViewModel(
sandook = get(),
analytics = get(),
ioDispatcher = get(named(IODispatcher)),
nswParkRideFacilityManager = get(),
parkRideService = get(),
parkRideSandook = get(),
stopResultsManager = get(),
flag = get(),
preferences = get(),
platformOps = get(),
infoTileManager = get(),
)
}

Perhaps it’s a bug then 🤔 I don’t see you do anything wrong with the ViewModel

[Karan Sharma]

Yea. It didn't happen before, i saw this in recent versions of koin only.

[Karan Sharma]

Will raise issue on github

[arnaud.giuliani]

need to check if it's a navigation bug 🤔

[arnaud.giuliani]

can you check with "regular" ViewModel API to see any difference ?
