GeoPolygon class

Represents a polygonal geofence area.

A GeoPolygon is defined by a list of GeoPoint vertices connected in order to form a closed shape.

Example:

final polygon = GeoPolygon(points: [
  GeoPoint(latitude: 37.7749, longitude: -122.4194),
  GeoPoint(latitude: 37.7849, longitude: -122.4094),
  GeoPoint(latitude: 37.7649, longitude: -122.4094),
]);

Constructors

GeoPolygon({required List<GeoPoint> points})

Creates a new GeoPolygon with the given points.

const

GeoPolygon.fromMaps(List<Map<String, double>> maps)

Creates a GeoPolygon from a list of coordinate maps.

factory

GeoPolygon.rectangle({required double north, required double south, required double east, required double west})

Creates a rectangular polygon from bounding coordinates.
