Pub Package Build Status Coverage Status GitHub Issues GitHub Forks GitHub Stars GitHub License

A library for area, distance, heading measurements (spherical_util.dart if port from android-maps-utils).

Getting Started #

In your dart/flutter project add the dependency:

   maps_toolkit: ^1.0.1+3

A simple usage example:

import 'package:maps_toolkit/maps_toolkit.dart';

main() {
  val distanceBetweenPoints = SphericalUtil.computeDistanceBetween(
    LatLng(51.5073509, -0.1277583),
    LatLng(48.856614, 2.3522219)

List of functions #

  • SphericalUtil.computeArea - calculate the area of a closed path on Earth.
  • SphericalUtil.computeDistanceBetween - calculate the distance between two points, in meters.
  • SphericalUtil.computeHeading - calculate the heading from one point to another point.
  • SphericalUtil.computeLength - calculate the length of the given path, in meters, on Earth.
  • SphericalUtil.computeOffset - calculate the point resulting from moving a distance from an origin in the specified heading (expressed in degrees clockwise from north).
  • SphericalUtil.computeOffsetOrigin - calculate the location of origin when provided with a point destination, meters travelled and original heading.
  • SphericalUtil.computeSignedArea - calculate the signed area of a closed path on Earth.
  • SphericalUtil.interpolate - calculate the point which lies the given fraction of the way between the origin and the destination.
