Map realated calculations in one place

Map related Calculations Package for Flutter

This package provides a set of utility classes and functions for performing map-related calculations in a Flutter application.

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 = MapCalculation.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 = MapCalculation.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 = MapCalculation.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 = MapCalculation.midpointBetween(point1, point2);
