Overview
A Dart implementation of Google's Polyline Encoding algorithm, used to compress latitude and longitude coordinates into a compact string format. This lossy compression reduces data size for map paths, making it ideal for efficient transmission and storage in geolocation applications. The package supports all major platforms including Android, iOS, Web, macOS, Windows, and Linux. It enables developers to encode and decode polylines with minimal overhead, maintaining sufficient accuracy for most mapping use cases.
Use cases
- Map route visualization
- Efficient GPS data transmission

- Geospatial data sharing
- Offline map data
Key features
- Lossy coordinate compression
- Cross-platform support
- Simple encoding/decoding API
- High performance
- Accurate for typical map distances
- Lightweight dependency
Suitable for
- Mobile and web mapping apps
- Location-based services
- Route planning tools
- Data-efficient geospatial APIs
- Applications handling large GPS datasets
Considerations
- Loss of precision due to compression
- Not suitable for high-accuracy scientific measurements
- Requires careful handling of edge cases in extreme latitudes
- Limited to polyline-only geometry
- May need validation for critical navigation systems
