NeshanPolygon class

A model representing a polygon on a Neshan map.

This class encapsulates all the properties needed to display a polygon using Mapbox GL JS GeoJSON sources and fill layers.

Usage Example

import 'package:flutter/material.dart';
import 'package:latlong2/latlong.dart';
import 'package:neshan_maps_flutter/map.dart';

final polygon = NeshanPolygon(
  id: 'area1',
  coordinates: [
    LatLng(35.700, 51.400),
    LatLng(35.710, 51.410),
    LatLng(35.720, 51.400),
    LatLng(35.700, 51.400),
  ],
  fillColor: Colors.blue.withOpacity(0.3),
  strokeColor: Colors.blue,
  strokeWidth: 2,
);

Constructors

NeshanPolygon({required String id, required List<LatLng> coordinates, Color? fillColor, double fillOpacity = 0.5, Color? strokeColor, double strokeWidth = 2.0, double strokeOpacity = 1.0})

Creates a new polygon.
