Is it possible that using the system back while transitioning to a screen breaks the navigation? Code on 🧵 (updating from 2.8.0-beta to 2.8.1 fixed this)

@Composable
fun PressBackDuringTransition() {
    val navController = rememberNavController()
    NavHost(
        navController = navController,
        startDestination = "screen_one",
    ) {
        composable("screen_one") {
            Box(
                modifier = Modifier
                    .fillMaxSize()
                    .background(Color.White),
                contentAlignment = Alignment.TopCenter,
            ) {
                Button(
                    onClick = {
                        navController.navigate("screen_two")
                    },
                ) {
                    Text(text = "Go to Screen Two")
                }
            }

                    Text(text = "Go to Screen One")

Which navigation version are you using?
They implemented support for seeking the transition back in tandem with system back. But this does seem to not finish the animation properly indeed

[Lisandro Di Meo]

Yeah, apparently if I remove the transition animation it works. I'm using "2.8.0-beta03"

[Lisandro Di Meo]

could it be that?

[Lisandro Di Meo]

Yeah, had to update to 2.8.1. Thanks for your comment, it made me realize that there was a newer version 👍
