Cuando hago doble clic en el mismo elemento o si voy a cada pantalla componible muy rápido, recibo un error. ¿Cómo soluciono este problema? Intenté cambiar algunas cosas, pero no puedo resolverlo y no puedo encontrar ningún recurso para solucionar este problema.
Implementación de navegación inferior
@Composable fun BottomNav( navController: NavController, bottomNavState: MutableState<Boolean>, ) { val navItems = listOf( Screen.HomeScreen, Screen.BookmarkScreen, Screen.MyRecipesScreen, Screen.FavouriteScreen ) AnimatedVisibility( visible = bottomNavState.value, enter = slideInVertically(initialOffsetY = { it }), exit = slideOutVertically(targetOffsetY = { it }), content = { BottomNavigation( backgroundColor = Color.White, elevation = 12.dp ) { val bottomNavBackStackEntry by navController.currentBackStackEntryAsState() val currentDestination = bottomNavBackStackEntry?.destination navItems.forEach { item -> BottomNavigationItem( icon = { Icon(painter = painterResource(id = item.icon), contentDescription = "") }, label = { Text(text = item.title) }, selected = currentDestination?.hierarchy?.any { it.route == item.route } == true, onClick = { navController.navigate(item.route) { popUpTo(navController.graph.findStartDestination().id) { saveState = true } launchSingleTop = true restoreState = true } }, selectedContentColor = Color.Black, unselectedContentColor = Color.LightGray, alwaysShowLabel = true, ) } } } ) }error recibido

No sé por qué está pasando.
Philip Dukhov tiene razón, debe informar este problema.
Aquí hay una solución sucia:
try { // The navigation code that throw this exception } catch (e: IllegalStateException) { if (e.message != "Already attached to lifecycleOwner") { throw e } else { // You can log the exception if you want } }Esto es de hecho un error de navegación. El problema es que se hace clic repetidamente en la pestaña. La solución temporal es volver igualmente.
NavigationBarItem( icon = { Icon(painterResource(id = screen.icon), contentDescription = screen.route) }, selected = currentRoute == screen.route, onClick = { if (currentRoute == screen.route) { return@NavigationBarItem } navController.navigate(screen.route) { popUpTo(navController.graph.findStartDestination().id) { saveState = true } launchSingleTop = true restoreState = true } } )
