Demo Module ::

Constructor:

To utilize Polyline, you need to call the constructor underneath:

 const Polyline({
    required this.polylineId,
    this.consumeTapEvents = false,
    this.color = Colors.black,
    this.endCap = Cap.buttCap,
    this.geodesic = false,
    this.jointType = JointType.mitered,
    this.points = const <LatLng>[],
    this.patterns = const <PatternItem>[],
    this.startCap = Cap.buttCap,
    this.visible = true,
    this.width = 10,
    this.zIndex = 0,
    this.onTap,
  });

Properties:

There are some properties of Polyline:

• > PolylineId — This property is used to uniquely identify a Polyline among GoogleMap polylines. This does not have to be globally unique, or unique among the list.
• > consumeTapEvents — This property is used to True if the Polyline consumes tap events. If this is false, the onTap callback will not be triggered.
• > Color — This property is utilized for the Line segment color in ARGB design, a similar configuration utilized by Color. The default value is black (0xff000000.
• > endCap — This property is utilized for the cap at the end vertex of the polyline. The default end cap is ButtCap. Supported on Android only.
• > visible — This property is utilized for True if the marker is visible.
• > width — This property is utilized to define the width of the line segment to be drawn. The width is constant and independent of the camera’s zoom level. The default value is 10.
• > points — This property is utilized for the vertices of the polyline to be drawn.
