GeomMultiLine.fromGeojson constructor

Implementation

GeomMultiLine.fromGeojson(Map<String, dynamic> inputJson, {bool withInvertedCoords = false}) {
  List<List<LatLng>> finalCoordinates = [];
  String? type = inputJson['type'];

  if(type != 'MultiLineString') {

      for (var coord in line) {
        final lat = coord[0].toDouble();

        lineCoords.add(withInvertedCoords ? LatLng(lon, lat) : LatLng(lat, lon));
      }
