当我双击同一个项目，或者如果我很快进入每个可组合屏幕，我会收到一个错误，我该如何解决这个问题？我试着改变了一些事情，但我就是解决不了，也找不到任何资源来解决这个问题.
底部导航实现
@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,
)
}
}
}
)
}
