Overview
turf_equality is a Flutter/Dart package that enables comparison of two GeoJSON objects, ensuring they are geometrically and structurally equivalent. Based on the popular turf.js library, it provides accurate spatial equality checks for geographic data, useful in validation and data integrity workflows. The package supports multiple platforms including Android, iOS, Web, macOS, Windows, and Linux, making it ideal for cross-platform geospatial applications. It integrates seamlessly with Flutter projects via pub.dev.
Use cases
- Validating GeoJSON data integrity
- Comparing map features during synchronization
- Testing geospatial logic in apps
- Ensuring consistency in GIS operations
- Verifying spatial data updates
Key features

- Supports all standard GeoJSON types
- Cross-platform compatibility
- Lightweight and easy to integrate
- Based on proven turf.js algorithms
Suitable for
- GIS developers
- Flutter apps with map features
- Data validation tools
- Spatial analysis applications
- Geospatial testing frameworks
Considerations
- Requires valid GeoJSON input
- May not handle non-standard GeoJSON extensions
- Performance depends on geometry complexity
- Limited to equality checks, not similarity or tolerance-based comparisons
