Overview
The latlng package provides essential geospatial utilities for Dart, supporting GeoJSON, geodesy, and geographical calculations. It includes the LatLong class for handling latitude and longitude coordinates and implements Mercator projection (EPSG:4326). Designed for cross-platform applications, it enables accurate location-based operations across Android, iOS, Web, macOS, Windows, and Linux. Ideal for developers building mapping features or working with geographic data in Flutter apps.
Use cases
- Geographic coordinate manipulation
- Map projections and conversions
