+# mgrs_dart
+
+Utility for converting between WGS84 lat/lng and MGRS coordinates (Dart version of [proj4js/mgrs](https://github.com/proj4js/mgrs)).
+
+Has 3 methods
+
+- forward, takes an array of `[lon,lat]` and optional accuracy and returns an mgrs string
+<!-- - inverse, takes an mgrs string and returns a bbox. -->
+- toPoint, takes an mgrs string, returns an array of '[lon,lat]'
