Tried to the NavigationExtensions.kt helper class to add navigation to BottomNavigationView, but getting

kotlin.TypeCastException: null cannot be cast to non-null type androidx.navigation.fragment.NavHostFragment at com.getinfino.android.view.home.NavigationExtensionsKt$setupItemReselected$1.onNavigationItemReselected(NavigationExtensions.kt:188)

Exception. The sample is working fine but not able to integrate it with my app.
