Serializable error after upgrading from 1.10 to 2.0

[jonneymendoza]

After migrating to version 2.0 of this library, whenever i navigate to a new screen from my navbar, i get the following error:

` E kotlinx.serialization.SerializationException: Serializer for class 'TvHomeScreenDestination' is not found. (Ask Gemini)
Please ensure that class is marked as '@serializable' and that the serialization compiler plugin is applied.

                                                                                                	at kotlinx.serialization.internal.Platform_commonKt.serializerNotRegistered(Platform.common.kt:90)

Here is where it breaks:

@composable
fun MainScreen() {
val navController: NavHostController = rememberNavHostEngine().rememberNavController()
val destinationNavigator = navController.rememberDestinationsNavigator()

var currentScreen = remember {
    ""
}

navController.addOnDestinationChangedListener { _, destination, _ ->
    currentScreen = when {
        destination.route?.contains(TopMovieListScreenDestination.route) == true -> TopMovieListScreenDestination.route
        destination.route?.contains(MovieScreenDestination.route) == true -> MovieScreenDestination.route
        else -> currentScreen // Keep currentScreen unchanged if no conditions are met
    }
}

MovieListPractiseTheme {
    Scaffold(topBar = {
        MovieTopBar(currentScreen, navigator = navController)
    }) { contentPadding ->
        Column(modifier = Modifier.padding(contentPadding)) {
            Box {
                MovieNavigationBar(destinationNavigator)
            }

            Box {
                DestinationsNavHost(navGraph = NavGraphs.root, navController = navController)
            }
        }
    }
}

}

///////////////////////////////////////////////////

@Composable
fun MovieNavigationBar(destinationsNavigator: DestinationsNavigator) {

    val currentSelected = remember {
        mutableStateOf<Selected>(Selected.Home)
    }

    NavigationBar {

        NavigationBarItem(
            selected = currentSelected.value is Selected.TV,
            onClick = {
                currentSelected.value = Selected.TV

            },
            icon = {
                Text(
                    text = stringResource(R.string.tv),
                    style = MaterialTheme.typography.labelMedium
                )
            })

}

This is the generated destinations for the TvHomeScreen

package com.ramcosta.composedestinations.generated.destinations

import androidx.compose.animation.AnimatedVisibilityScope
import androidx.compose.runtime.Composable
import androidx.navigation.NavBackStackEntry
import androidx.navigation.NavHostController

/**

 */
public data object TvHomeScreenDestination : BaseRoute(), DirectionDestinationSpec {
    
    public operator fun invoke(): Direction = this
    
    override val baseRoute: String = "tv_home_screen"

    override val route: String = baseRoute
    
    @Composable
    override fun DestinationScope<Unit>.Content() {
		TvHomeScreen(
			navigator = destinationsNavigator
		)
    }
    
}

The TVHomeScreen code

@Destination<RootGraph>
@Composable
fun TvHomeScreen(
    navigator: DestinationsNavigator,
    tvHomeScreenViewModel: TvHomeScreenViewModel = hiltViewModel()
) {
    MovieListPractiseTheme {
        val tvHomeScreenEvents = object : TvHomeScreenEvents {
            override fun onTvShowClicked(tvShowId: Int) {
                navigator.navigate(TvShowDetailScreenDestination(tvShowId = tvShowId))
            }
        }
        when (val state = tvHomeScreenViewModel.state.collectAsState().value) {
            is TvHomeScreenState.ContentRetrieved -> TvContentSection(
                contentState = state,
                tvHomeScreenEvents = tvHomeScreenEvents
            )

            is TvHomeScreenState.Error -> ErrorScreen(throwable = state.throwable)
            TvHomeScreenState.Loading -> LoadingScreen()
        }
    }
}
