1. Add Icon Vector Asset

In this example, you're adding the ic_home.xml and ic_search.xml vector assets for the screen navigation tab.

This highlights the steps :

  • New -> Vector Asset
  • Click on the Clip Art to select the Icon asset
  • Rename it

You may get the following compilation error after adding those icons.

AAPT: error: resource attr/colorControlNormal not found.

It is because of the dependency on the androidx.appcompat:appcompat library, which is not required by Jetpack Compose app.

To fix the error, add this library into your app\build.gradle file:

dependencies {
    // required by "?attr/colorControlNormal" ic_home.xml
    implementation 'androidx.appcompat:appcompat:1.4.1'

2. Add BottomNavigation() Composable

androidx.compose.material.BottomNavigation() composable function is used to implement the bottom bar navigation.

fun BottomBarNavigation(navController: NavController) {
    val navBackStackEntry by navController.currentBackStackEntryAsState()
    val currentRoute = navBackStackEntry?.destination?.route

    if (currentRoute == null || currentRoute == NavRoute.Login.path) {

    BottomNavigation {
        // implement each navigation tab with BottomNavigationItem() here

navController.currentBackStackEntryAsState() is used so that it can retrigger the composable function to run when the navigation route is changed.

3. Add BottomNavigationItem() Composable

In the BottomNavigation(), you add the RowScope.BottomNavigationItem() for each row navigation tab.

BottomNavigation {

    val homeSelected = currentRoute == NavRoute.Home.path
        icon = {
                painter = painterResource(R.drawable.ic_home),
                contentDescription = NavRoute.Home.path
        selected = homeSelected,
        onClick = {
            if(!homeSelected) {
                navController.navigate(NavRoute.Home.path) {
                    popUpTo(NavRoute.Home.path) { inclusive = true }
        label = {Text(NavRoute.Home.path)}

icon, selected and onClick are mandatory parameters, the rest are optional.

4. Implement Scaffold bottomBar

To add BottomBarNavigation(), you call it from the Scaffold -> bottomBar parameter as the following:

val navController = rememberNavController()

    bottomBar = { BottomBarNavigation(navController = navController) }
) {
