The raw_gnss package enables Flutter applications to access raw Global Navigation Satellite System (GNSS) data on Android, iOS, and macOS. It provides real-time events for GNSS measurements, navigation messages, and status updates, offering developers low-level insights into satellite positioning. This is particularly useful for high-precision location tracking, research, or advanced geospatial applications requiring detailed GNSS information beyond standard location services.
