Hi, I don't think that could be related to the editor, as it doesn't know (or care) about the shape (iirc, it's a while since I did it), it just edits a list of points. So I'm unsure that it could be related to it, unless there's something I'm missing.
Maybe it's worth showing the code...are you sure you aren't repeatedly redrawing the shape multiple times or something ?

my code
class _RequestDrawScreenState extends State<RequestDrawScreen> {
final MapController mapController = MapController();
final List<Marker> userLocationMarkers = <Marker>[];
PolyEditor polyEditor;
List<Polygon> polygons = [];
var testPolygon =
new Polygon(color: Colors.deepOrange.withOpacity(0.1), points: []);
@override
void initState() {
super.initState();
polyEditor = new PolyEditor(
points: testPolygon.points,
pointIcon: Icon(
Icons.crop_square,
size: 23,
),
intermediateIcon: Icon(Icons.lens, size: 15, color: Colors.grey),
callbackRefresh: () => {this.setState(() {})});
}
@override
Widget build(BuildContext context) {
polygons.add(testPolygon);
return Scaffold(
body: SafeArea(
child: Stack(
children: [
FlutterMap(
mapController: mapController,
options: MapOptions(
onTap: (latLog) {
polyEditor.add(testPolygon.points, latLog);
print(latLog);

I haven't run it, but it looks like you're not resetting your polygons list every build, so as mentioned you're readding it every build, so you will end up with a list of repeated testpolygons. Try adding in polygons = [] as first line in build method.

Thanks for the answer, it works. @ibrierley
