MutableState continuously emitting data

Question

I am facing one strange issue. I am trying to make login screen screen and once login is successful i am navigating user to home screen.

So issue is that after successful login navigateToDashboard is continuously emitting data. The user is navigated to home screen but in logs it continuously prints called. Also i am not able go back from home screen.

ViewModel

private var _navigateToDashboard: MutableStateFlow<Boolean> = MutableStateFlow(false)
var navigateToDashboard: StateFlow<Boolean> = _navigateToDashboard

fun loginUser() {
    viewModelScope.launch(Dispatchers.IO) {
        isLoading.value = true
        try {
            val response = repo.loginUsers(email = email.value, password = password.value)
            pref.storePrefValue(UserPreferences.token, response.data?.authToken ?: "")
            pref.storePrefValue(
                UserPreferences.loginData,
                AppUtility.modelToJson(response) ?: ""
            )
            isLoading.value = false
            _navigateToDashboard.value = true
            Timber.e("ho")
        } catch (exception: Exception) {
            isLoading.value = false
            Timber.e(exception)
        }
    }
}

Login Screen

Column(
    Modifier.fillMaxWidth().fillMaxHeight().padding(40.dp),
    ) {
    val authViewModel: AuthViewModel = hiltViewModel()
    val navigateToDashboard by authViewModel.navigateToDashboard.collectAsState()

    if (navigateToDashboard) {
        Timber.e("called")
        navController.popBackStack()
        navController.navigate("home")
    } else {

        AppTextInput(
            "Email Id",
            value = authViewModel.email.value,
            modifier = Modifier.fillMaxWidth().padding(top = 20.dp)
                .focusRequester(focusRequester),
            keyboardOptions = KeyboardOptions(
                keyboardType = KeyboardType.Email,
                imeAction = ImeAction.Next
            ),
            keyboardActions = KeyboardActions(onNext = {
                focusManager.moveFocus(FocusDirection.Down)
            }),
        ) {
            authViewModel.setEmail(it)
        }
        AppTextInput(
            "Password",
            value = authViewModel.password.value,
            modifier = Modifier.fillMaxWidth().padding(top = 20.dp),
            keyboardActions = KeyboardActions(onDone = {
                keyboardController?.hide()
            }), visualTransformation = PasswordVisualTransformation()
        ) {
            authViewModel.setPassword(it)
        }
      
        LoadingButton(
            isLoading = authViewModel.isLoading.value,
            title = "Login",
            boxModifier = Modifier.padding(top = 10.dp).fillMaxWidth(),
            buttonModifier = Modifier.fillMaxWidth()
        ) {
            keyboardController?.hide()
            authViewModel.loginUser()

        }
    }
