Polyline

Polyline is a set of points where line segments are drawn between consecutive points. For example, you can give a set of latitude, longitude coordinates as input, and lines are drawn connecting these points.

The following image is an example of a polyline that connects two points:

The Polyline object consists of a set of latitude, longitude coordinates and it connects the points to each other.

Creating a polyline

A polyline can be created using a PolylineOptions object. By calling the add() method on the PolylineOptions object, you can add latitude, longitude coordinates to the polyline. The add() method takes the LatLng object as a parameter. The polyline can be added to the Google map by calling the addPolyline() method on the GoogleMap object, which takes the PolylineOptions object as a parameter...
