MultiPolygons issues: Error parsing geojson: type 'int' is not a subtype of type 'double' in type cast #25
Description
Hello,
I have issue with some of my geojson files when they are multipolygons, can you help me?
A very simple use of the geoJsonParser
`
GeoJsonParser geoJsonParser = GeoJsonParser(
defaultMarkerColor: Colors.red,
defaultPolygonBorderColor: Colors.red,
defaultPolygonFillColor: Colors.red.withOpacity(0.25),
defaultCircleMarkerColor: Colors.red.withOpacity(0.25),
);
var parsedGeoJson = jsonDecode(geojsonson);
geoJsonParser.parseGeoJson(parsedGeoJson);
setState(() {
polygons = geoJsonParser.polygons;
});
`
Here is a sample of data:
