android - How to call function after updating data in room persistence library

Question

This is my function inside viewModel class:

fun updateMenu(menu: Menu) = viewModelScope.launch {
    menuDao.update(menu) // updating menu to database
    total = hitungTotal() // calculate all subtotal to total
}

private fun hitungTotal(): Int {
    var sum = 0
    menuList.value?.apply {
        for (i in this.indices) sum += this.get(i).subTotal
    }
    return sum
}

I want hitungTotal() function to be executed after the database is updated. How to achieve this?
