        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>

Add menu items in code.

val bottomNavigation = findView(R.id.bottomNavigation)
bottomNavigation.add(MeowBottomNavigation.Model(1, R.drawable.ic_home))
bottomNavigation.add(MeowBottomNavigation.Model(2, R.drawable.ic_explore))
