I have Multiple screens as Composable like HomeScreen, DashboardScreen, etc and all of them has it's own ViewModel e.g HomeViewModel and I'm using ViewModel as

val viewModel: HomeViewModel = viewModel()

in each screen, Do these ViewModels remain in memory all the time because I'm using a Single Activity? and I'm not using Navigation Component

it lives as long as

AmbientViewModelStoreOwner.current
