Polygon constructor

Polygon(List<Offset> points)

Create a Polygon with vertices at points. Pass a List<Point<num>>

Implementation

Polygon(List<Offset> points) : points = points.toList(growable: false) {
  var numberOfPoint = this.points.length;
  if (numberOfPoint < 3) {
    throw NeedsAtLeastThreePoints(numberOfPoint);
  }
}
