I was trying to follow this video for my login flow.

But I am facing a problem. Details in the thread.

[Rafiul Islam]

On my homepage, I am using the following code. Here viewmodel.user is a MutableState.

val loginState = savedStateHandle.getLiveData<Boolean>("LOGIN_SUCCESS").observeAsState()

if (viewModel.user.value == null) {
    LaunchedEffect(viewModel.user.value) {
        navController.navigate(Screens.Login.id)
    }
}
when (loginState.value) {
    false -> {
        onFinish()
    }
    true -> {
        MainContent()
    }
}

And In Login Screen

AuthUiState.LoggedIn -> {
    savedStateHandle?.set("LOGIN_SUCCESS", true)
    navController.popBackStack()
}

But the problem is when I use popBackStack() and go back to my homepage the following block runs again and go back to the login page again because of viewModel.user.value is still null. Since I am using two different viewModels LoginViewModel and HomeViewModel so I can't update viewModel.user value directly from the LoginViewModel right after the successful login instead, I update it from the MainContent() in HomeViewModel .

if (viewModel.user.value == null) {
    LaunchedEffect(viewModel.user.value) {
        navController.navigate(Screens.Login.id)
    }
}

What is the appropriate way of updating user value when using two different ViewModel? So that the navigation block doesn't execute again when I pop back to my homepage.
