Variable instructions #
Calculates the distance between two GPS coordinates in either miles or kilometers.
The function takes in four required parameters:

[lat1]: The latitude of the first coordinate.
[lon1]: The longitude of the first coordinate.
[lat2]: The latitude of the second coordinate.
[lon2]: The longitude of the second coordinate.

The function also takes in one optional parameter:

[km]: A boolean value that determines whether the distance should be returned in kilometers (true) or miles (false).

If [km] is not provided, it defaults to false (miles).
If any of the coordinates are not provided, they default to the following values:

lat1: 34.052235
lon1: -118.243683
lat2: 40.754932
lon2: -73.984016

Returns the distance between the two coordinates in either miles or kilometers.
Example #
import 'package:longitude_and_latitude_calculator/longitude_and_latitude_calculator.dart';

void main() {
var lonAndLatDistance = LonAndLatDistance();

final double miles = lonAndLatDistance.lonAndLatDistance(
lat1: 34.052235,
lon1: -118.243683,
lat2: 40.754932,
lon2: -73.984016,
km: false);

final double Kilometer = lonAndLatDistance.lonAndLatDistance(
lat1: 34.052235,
lon1: -118.243683,
lat2: 40.754932,
lon2: -73.984016,
km: true);
