geojson_vi 2.2.5

An Open-Source Dart and Flutter Library for Efficiently Handling GeoJSON Data in Compliance with RFC 7946

CHANGELOG

2.2.5 - 2024-06-27

Added

• Support for null geometry values in GeoJSONFeature and GeoJSONFeatureCollection according to the GeoJSON spec.

Fixed

• Issue with GeoJSONFeature.fromMap(...) and GeoJSONFeatureCollection.fromMap(...) not allowing null geometry values.
• Updated findNearestFeature to handle features with null geometry.
• Updated bbox calculation to handle null geometry.

2.2.4 - 2024-04-27

Added

• None

Changed

• Enhanced the _removeBbox function to include null safety checks and an identity comparison to optimize performance and reliability. This improvement prevents unnecessary computations by checking if the input bounding boxes (bbox1 and bbox2) are identical or if bbox2 is null, thereby returning bbox1 directly under these conditions.

Deprecated

• None

Removed

• None

Fixed

• None

Security

• None

2.2.3 - 2024-03-27

Added

• Added isPointInside method in GeoJSONPolygon to check if a point is inside a given polygon.
• Added isPointInsideComplex in GeoJSONPolygon to determine if a point lies within a complex polygon while considering holes.
• Added optimalPointInside method to GeoJSONPolygon for calculating the optimal point within a polygon, enhancing label placement in geospatial analyses.

[2.2.2] - 2024-03-15

• Resolved RangeError in equality comparison for GeoJSONPolygon when comparing polygons with different point counts (Issue #23).
• Improved equality comparison for GeoJSONMultiPolygon and GeoJSONMultiLineString to handle nested structures more effectively, addressing the concerns raised in Issue #23
