      latitude1: lat1, longitude1: lon1, latitude2: lat2, longitude2: lon2);

  print(
      'Distance from location 1 to 2 using the Spherical Law of Cosines is: ${gcd.sphericalLawOfCosinesDistance()}');
  print(
      'Distance from location 1 to 2 using the Vicenty`s formula is: ${gcd.vincentyDistance()}');
