Description:

flexible polyline dart

Flexible Polyline encoder/decoder for Dart #
The flexible polyline encoding is a lossy compressed representation of a list of coordinate pairs or
coordinate triples.
Usage #
Encoding #
List<LatLngZ> pairs = List<LatLngZ>();
pairs.add(LatLngZ(50.1022829, 8.6982122));
pairs.add(LatLngZ(50.1020076, 8.6956695));
pairs.add(LatLngZ(50.1006313, 8.6914960));
pairs.add(LatLngZ(50.0987800, 8.6875156));

String encoded = FlexiblePolyline.encode(pairs /* coordinates */,
5 /* coordinate precision */, ThirdDimension.ABSENT /* third dimension */,
0 /* third dimension precision */);

Decoding #
List<LatLngZ> decoded =
FlexiblePolyline.decode("BFoz5xJ67i1B1B7PzIhaxL7Y");
