S2 Geometry for Dart

Dart port of the C++ s2geometry and Go geo libraries.

Usage

A simple usage example:

import 'package:armi_s2geometry/armi_s2geometry.dart';

main() {
  S2LatLng latLng = new S2LatLng.fromDegrees(10.4883764, -73.2721948);
  S2CellId cellId = new S2CellId.fromLatLng(latLng).parent(14);
  print(cellId.toToken());
}

Notes

This library depends on int being a 64 bit signed integer, and thus may not work under JavaScript targets.
