geoCode method

Future<GeoCodeResponse> geoCode({ String? country, String? state, String? county, String? city, String? district, String? street, String? houseNumberOrName, String? postalCode, String? searchtext, })

geoCode can be used to retrieves the latitude, longitude and complete address details based on the searchText provided

Implementation

Future<GeoCodeResponse> geoCode({
  String? country,
  String? state,
  String? county,
  String? city,
  String? district,

  String? searchtext,

          houseNumberOrName != null ||
          postalCode != null ||
          searchtext != null,
      'At least one argument is required.');
