    Polyline({
      @required this.points,
      this.width = 10,
      this.visible = true,
      this.geodesic = false,
      this.alpha = 1.0,
      this.dashLineType = DashLineType.none,
      this.capType = CapType.butt,
      this.joinType = JoinType.bevel,
      this.customTexture,
      this.onTap,
      this.color = const Color(0xCCC4E0F0),
    })  : assert(points != null && points.length > 0),
          super();
