I'm creating a simple app with bottom navigation and drawer.
I wrap all screens inside a Scaffold with topbar and bottom bar. I want to hide top bar and bottom bar on a specific screen. Does anyone know to how achieve that
here is the code for setting up navigation.
val navController = rememberNavController()
val scaffoldState = rememberScaffoldState(rememberDrawerState(DrawerValue.Closed))
Scaffold(
bottomBar = {
AppBottomBar(navController)
},
topBar = {
AppTopBar(scaffoldState)
},
drawerContent = {
DrawerContent(navController, scaffoldState)
},
scaffoldState = scaffoldState
) {
// ovoid bottom bar overlay content
Column(modifier = Modifier.padding(bottom = 58.dp)) {
AppNavigation(navController)
}
}
AppNavigation
contains NavHost
for navigating to screens
for now, I can achieve that by checking current route to show or hide bottomBar, topBar. But I think there's must be better solutions. The way I wrap all screens inside Scaffold might not right.
val navController = rememberNavController()
val scaffoldState = rememberScaffoldState(rememberDrawerState(DrawerValue.Closed))
Scaffold(
bottomBar = {
if (currentRoute(navController) != "Example Screen") {
AppBottomBar(navController)
}
},
topBar = {
AppTopBar(scaffoldState)
},
drawerContent = {
DrawerContent(navController, scaffoldState)
},
floatingActionButton = {
FloatingButton(navController)
},
scaffoldState = scaffoldState
) {
// ovoid bottom bar overlay content
Column(modifier = Modifier.padding(bottom = 58.dp)) {
AppNavigation(navController)
}
}
@Composable
public fun currentRoute(navController: NavHostController): String? {
val navBackStackEntry by navController.currentBackStackEntryAsState()
return navBackStackEntry?.arguments?.getString(KEY_ROUTE)
}
