                  await (await _googleMapController.future).moveCamera(
                      CameraUpdate.newCameraPosition(CameraPosition(

            ),
          ),
        ),
      ],
    );
  }
}

I'm getting error in AddressSearchField and AddressPoint. I get the address_search_field and google_maps_controller packages. What should i do?
