Compose Foundation: v1.9.0-alpha03

May 20, 2025

@Serialiable object Home : NavKey
@Serialiable object Chat : NavKey
val backStack = rememberNavBackStack(Home)
NavDisplay(backStack, entryProvider = entryProvider {

  entry<Home> {

    Column {

      Text(“Home”)

      Button(onClick = { backStack.add(Chat) } ) {

        Text(“Go to Chat”)

      } 

    }

  }

  entry<Chat> { /* My Composable Content */ }

})
