Performance tips for Navigation component in Android?

// Example: Efficient use of Navigation Component with fragment caching
class NavigationActivity : AppCompatActivity() {
    private lateinit var navController: NavController

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_navigation)

        navController = findNavController(R.id.nav_host_fragment)

        // Optimize by using a single shared ViewModel for multiple fragments.
        val sharedViewModel = ViewModelProvider(this).get(SharedViewModel::class.java)

        // Setup the navigation with the controller
        setupActionBarWithNavController(navController)
    }

    override fun onSupportNavigateUp(): Boolean {
        // Handle the up navigation correctly
        return navController.navigateUp() || super.onSupportNavigateUp()
    }
}
