Static Methods

compressPath(List<LatLng> path, {required double minimumDistanceMeters, required double simplificationToleranceMeters, required int precision, List<LatLng> preservePoints = const []}) → PathCompressionResult

Filters, simplifies, rounds, and encodes a raw list of path coordinates.

compressPathModel(PathModel pathModel, {required double minimumDistanceMeters, required double simplificationToleranceMeters, required int precision}) → EncodedPathModel

Compresses a saved PathModel and returns an EncodedPathModel.

decodePolyline(String encodedPath, {int precision = 5}) → List<LatLng>

Decodes a polyline string back into path coordinates.

encodePolyline(List<LatLng> path, {int precision = 5}) → String

Encodes path into a Google-style polyline string.

resolvePath(EncodedPathModel encodedPathModel) → List<LatLng>

Decodes the route inside encodedPathModel back into a coordinate list.
