How can a screen switching mechanism be implemented in Jetpack Compose?

In Jetpack Compose, screen switching is usually implemented using the Navigation Compose library, which manages navigation between different Composables.

Main steps:

1. Create a NavHost that contains a NavController and defines the navigation graph.
2. Define composables for each screen with a unique route.
3. Use NavController to navigate between screens by calling navigate().

Example:

val navController = rememberNavController()

NavHost(navController = navController, startDestination = "home") {
    composable("home") { HomeScreen(onNavigate = { navController.navigate("details") }) }
    composable("details") { DetailsScreen() }
}

@Composable
fun HomeScreen(onNavigate: () -> Unit) {
    Button(onClick = onNavigate) {
        Text("Go to details screen")
    }
}

@Composable
fun DetailsScreen() {
    Text("Details screen")
}

This approach makes it easy to manage the stack of screens and navigation parameters.
