A Dart library designed for precise geodesic and trigonometric calculations, enabling accurate distance, bearing, and path computations between geographic points. It supports operations on points and paths using spherical geometry, making it ideal for mapping and location-based applications. The library is platform-agnostic, working seamlessly across Android, iOS, Web, macOS, Windows, and Linux. It is particularly useful for applications requiring high accuracy in navigation, route planning, or spatial analysis.
Use cases
- Calculating distances between geographic coordinates
