Несоответствие типа: NavController (NavHost)

Question

Я новичок в Jetpack Compose Kotlin. Несоответствие типов: предполагаемый тип — NavController, но ожидался NavHostController. Фрагмент кода в MainActivity, который вызывает ошибку NavHost(navController = navController, startDestination = APPS_ROUTE) {

      fun BodyContent(paddingValues: PaddingValues, navController: NavController) {
    Column(modifier = Modifier.padding(paddingValues)) {
        NavHost(navController = navController, startDestination = APPS_ROUTE) {
            composable(APPS_ROUTE) { AppsScreen() }
            composable(WIDGETS_ROUTE) { WidgetsScreen() }
            composable(SETTINGS_ROUTE) { SettingsScreen() }
        }
    }
}

Несоответствие типов Обязательно: NavHostController Найдено: параметр-значение NavController navController: NavController

Это мой код в MainActivity.kt

Как я могу решить эту проблему? Спасибо

Я пытался добавить import androidx.navigation.compose.NavHostController и другие части пакета, но это не помогло.
