Calculating Distance Between Two Points #

You can use the 'distanceBetween' function to calculate the distance between two points on a map. The function takes five arguments: the latitude and longitude of the first point, and the latitude and longitude of the second point and the units you want the distance in.

double distance = FlutterMapMath.distanceBetween(
    37.4219999,
    -122.0840575,
    37.4220011,
    -122.0866519,
    "meters"
);

Available return units are : meters, kilometers, yards and miles. Replace the meters from above example to your required units.

Calculating Bearing Between Two Points #

You can use the 'bearingBetween' function to calculate the bearing between two points on a map. The function takes four arguments: the latitude and longitude of the first point, and the latitude and longitude of the second point. The function returns the bearing in degrees.

double bearing = FlutterMapMath.bearingBetween(
    37.4219999,
    -122.0840575,
    37.4220011,
    -122.0866519,
);

Calculating Destination Point #

You can use the 'destinationPoint' function to calculate the destination point from a starting point, given a distance and a bearing. The function takes three arguments: the latitude and longitude of the starting point, the distance in meters, and the bearing in degrees. The function returns a LatLng object representing the destination point.

LatLng startingPoint = LatLng(37.4219999, -122.0840575);
double distance = 1000;
double bearing = 90;
LatLng destinationPoint = FlutterMapMath.destinationPoint(startingPoint, distance, bearing);

Calculating Midpoint Between Two Points #

You can use the 'midpointBetween' function to calculate the midpoint between two points on a map. The function takes four arguments: the latitude and longitude of the first point, and the latitude and longitude of the second point. The function returns a LatLng object representing the midpoint.

LatLng point1 = LatLng(37.4219999, -122.0840575);
LatLng point2 = LatLng(37.4220011, -122.0866519);
LatLng midpoint = FlutterMapMath.midpointBetween(point1, point2);

fixes

added 'calculateIntersection' function to find the intersection point of two lines.

Added proximity detection function

Added function to create virtual boundaries

Added function to find area of the shape

minor fix

Instead of passing latitude and longitude to the calculateIntersection function, just pass the two points as LatLng objects.

Instead of passing latitude and longitude to the midpointBetween function, just pass the two points as LatLng objects.
