How can I hide bottom navigation bar on scroll of a LazyColumn inside a HomeTab?

[terrakok]

One alternative if you use koin is to create an observable on the bottomBar composable function:

val bottomBarVisibilityManager: BottomBarVisibilityManager = koinInject()
var isBottomBarVisible = remember { mutableStateOf(true) }
bottomBarVisibilityManager.observeBottomBarVisibility { isVisible ->
    isBottomBarVisible.value = isVisible
}
if (isBottomBarVisible.value) {YourBottomBar()}

class BottomBarVisibilityManagerImpl : BottomBarVisibilityManager {

    private val _bottomBarVisible = MutableStateFlow(true)
    override val bottomBarVisible: StateFlow<Boolean> = _bottomBarVisible.asStateFlow()

    private val coroutineScope = CoroutineScope(Dispatchers.Main) // Use Dispatchers.Main for UI updates

    override fun setBottomBarVisibility(visible: Boolean) {
        _bottomBarVisible.value = visible
    }

    override fun isBottomBarVisible(): Boolean {
        return _bottomBarVisible.value
    }

    override fun observeBottomBarVisibility(observer: (Boolean) -> Unit) {
        coroutineScope.launch {
            bottomBarVisible.collect { isVisible ->
                observer(isVisible)
            }
        }
    }
}
