   …in cloud_firestore . The old names still work as deprecated aliases, and will be removed in a future breaking release. Run dart fix --apply to migrate…

   This release is backward compatible with 0.0.6: existing code keeps working, geohashes are unchanged, and query ranges only change where they used to miss results.

   Added

   • decodeGeoHash and decodeGeoHashBounds, which decode a geohash into the center or the bounds (GeoHashBounds) of its cell.
   • geoHashNeighbors, which returns the cells adjacent to a geohash, keyed by GeoHashDirection.
   • isValidGeoHash, which checks a geohash without throwing.
   • isWithinRadius, which filters query results using a radius in meters, the same unit as geohashQueryBounds.
   • GeoHashPoint.toString, which makes error messages show the coordinates instead of Instance of 'GeoPoint'.
   • Data for dart fix, which migrates code to the renamed classes.

   Changed

   • The package no longer depends on the Flutter SDK. It still works in Flutter apps, and can now also be used in any Dart project, such as a server.
   • Added explicit return types to log2, validateKey and validateLocation.
   • Documented the whole public API and rewrote the README, including a complete guide to querying Cloud Firestore by distance.
   • Added reference, property and regression tests, and continuous integration.

   Deprecated

   • MyGeoHash is renamed to GeoHashUtils, and GeoPoint to GeoHashPoint. The new names don't clash with the classes of other packages, such as GeoPoint in cloud_firestore. The old names still work as deprecated aliases, and will be removed in a future breaking release. Run dart fix --apply to migrate.

   Fixed

   • geohashQueryBounds missed locations within the radius when the search area reached towards a pole or spanned more than half of the globe's longitudes. Ranges for other queries are unchanged.
   • distanceBetween returned NaN for some nearly antipodal locations.
   • validateKey accepted keys containing ., #, $, /, [, ] or ASCII control characters, which the Firebase Realtime Database rejects. It now throws for them, as documented.
   • geohashQueryBounds threw an UnsupportedError for a negative, NaN or infinite radius. It now throws an ArgumentError describing the problem.
