Re-explain

Using Safe Args plugin:

// In navigation XML
<fragment android:id="@+id/detailFragment">
    <argument
        android:name="userId"
        app:argType="integer" />
</fragment>

// Passing data
val action = UserListFragmentDirections.actionToDetail(userId = 123)
findNavController().navigate(action)

// Receiving data
class DetailFragment : Fragment() {
    private val args: DetailFragmentArgs by navArgs()
    
    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        val userId = args.userId
    }
}
