area property

@override double area

Gets the area of the geometry.

This should be implemented by subclasses to compute the correct area.

Implementation

@override
double get area {
  var exteriorRing = coordinates[0];
  var area = getGeographicArea(exteriorRing);
  for (var i = 1; i < coordinates.length; i++) {
    var interiorRing = coordinates[i];
    area -= getGeographicArea(interiorRing);
  }
  return area;
}
