NavigationModel.fromJson constructor

Implementation

    for (var coord in coordinates) {
      final latLng = LatLng(coord[1] * 1.0, coord[0] * 1.0);
      geometry!.add(latLng);
    }
  }
  chunkDatas = <ChunkDatas>[];

  final features = json['steps'];
  if (features != null) {

        i,
      );
