Think of a new way to create a ScreenModel in a Screen

[dragossusi]

I am using SplitPane with Scaffold and I want to keep a single Scaffold.

I use TabsNavigator and a NavigationRail for the first part of the creen and Navigator with a single Scaffold like:

abstract class AppTab<S : AppScreen>(
    private val startScreen: S
) : Tab {

    @OptIn(ExperimentalMaterial3Api::class)
    @Composable
    final override fun Content() {
        Navigator(startScreen) { navigator ->
            val screen = navigator.lastItem as AppScreen
            val scrollBehavior = remember {
                TopAppBarDefaults.enterAlwaysScrollBehavior()
            }
            Scaffold(
                modifier = Modifier.nestedScroll(scrollBehavior.nestedScrollConnection),
                topBar = {
                    SmallTopAppBar(
                        title = { screen.Title() },
                        navigationIcon = {
                            if (navigator.canPop) {
                                BackButtonUi { navigator.pop() }
                            }
                        },
                        actions = {
                            screen.Actions(navigator)
                        },
                        colors = TopAppBarDefaults.smallTopAppBarColors(
                            containerColor = MaterialTheme.colorScheme.secondaryContainer
                        ),
                        modifier = Modifier.shadow(2.dp)
                    )
                }
            ) {
                Box(
                    modifier = Modifier.padding(it)
                ) {
                    CurrentScreen()
                }
            }
        }
    }
}

In Actions I create a button that calls a method on a ScreenModel, but I need to call the rememberScreenModel twice, once in Content and once in Actions:

class SomeRightScreen(
    private val arg: Arg
) : RunScreen() {

    @Composable
    override fun Title() {
        Text(state.label)
    }

    @Composable
    override fun ScreenContent() {
        val viewModel: SomeScreenModel = rememberScreenModel {
            bindProvider { arg }
        }
        val uiState by viewModel.state.collectAsState()
        SomeUi(uiState)
    }

    @Composable
    override fun Actions(navigator: Navigator) {
        val viewModel: SomeScreenModel = rememberScreenModel {
            bindProvider { arg }
        }
        val uiState by viewModel.state.collectAsState()
        IconButton(
            onClick = {
                viewModel.doSomething()
            }
        ) {
            Icon(Icons.Default.Check, "Done")
        }
    }
}

Hi all, I have just published a fork of voyager with bug fixes and new features here.
In my fork is very easy to share data between Screen and composable in the same composable subtree as some screen, using blocs
I will be happy to have your feedback.
