Destination for multi module project.

[youndon]

I have multi module project working on, And I decided to switch from compose navigation to @destination library.
But I get an issue if I tried to navigate from module to another, Unlike single module that goose well.

For example:

:app

class MainActivity : ComponentActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContent {
            DestinationTestTheme {
                // A surface container using the 'background' color from the theme
                Surface(
                    modifier = Modifier.fillMaxSize(),
                    color = MaterialTheme.colorScheme.background
                ) {
                    DestinationsNavHost(navGraph = NavGraphs.root)
                }
            }
        }
    }
}


@RootNavGraph(start = true)
@Destination
@Composable
fun South(
    destinationsNavigator: DestinationsNavigator
) {

    Box {

        Button(onClick = {
            destinationsNavigator.navigate(NorthDestination("azertyu", 132456))

        }) {
            Text("nav to north!")
        }
    }
}

:north

@Destination(start = true)
@Composable
fun North(
    string: String?,
    int: Int?
) {
    Column {
        Text(text = string.toString())
        Text(text = int.toString())
    }
}

The application can run but the exception happen when click the button to navigate the other screen.

The Log:

java.lang.IllegalArgumentException: Navigation destination that matches request NavDeepLinkRequest{ uri=android-app://androidx.navigation/north?string=iuytrhkgfckhygf&int=321654 } cannot be found in the navigation graph ComposeNavGraph(0x78dcd1ef) route=root startDestination={Destination(0xa2cb9a60) route=south}

Your destinations from one module doesn’t automatically belong to root graph you use to pass to DestinationsNavHost.

Multi module setup is improving greatly for v2 so my advice is stay tuned for documentation I am writing right now and when that is up, use v2.
