val navController = rememberNavController()
Finally create the NavHost using both the NavController and which screen to start with startDestination
NavHost(
navController = navController,
startDestination = Screen.SplashScreen.route
){
composable(Screen.SplashScreen.route) { BaseComponent { SplashScreen(navController = navController) } }
composable(Screen.Home.route) { BaseComponent { CoffeeListScreen(navController = navController) } }
composable("${Screen.Details.route}/{id}") {
BaseComponent {
DetailsScreen(coffee = it.arguments?.getString("id", "1")?.toInt()!!)
}
}
}
