This is how the Custom result contract AddressAutoComplete.kt is called.

AddressFragment.kt

class AddressFragment : Fragment() {   
    private lateinit var binding: AddressFragmentBinding
    private var launcher = registerForActivityResult(AddressAutoComplete()) { place ->

            if (place != null) {

                val geocoder = Geocoder(activity)
                var address : Address? = null

                try {
                    if (place.address != null) {

                        //Get the first result
                        address = geocoder.getFromLocationName(place.address, 1)[0]
                    }
                } catch (e: IOException) {
                    e.printStackTrace()
                }

                Log.e("Fragment","Address $address")
                
          with(binding){

                if (address != null) {
                    streetAddressValue.text = "${address.subThoroughfare} ${address.thoroughfare}"
                    cityAddressValue.text = address.locality
                    stateAddressValue.text = address.adminArea
                    zipCodeAddressValue.text = address.postalCode
                    countryAddressValue.text = address.countryName

                }

            }


            }
        
        }
   override fun onCreateView(
        inflater: LayoutInflater, container: ViewGroup?,
