Name	Type	Description
polylineId	PolylineId	Unique polyline ID.
clickable	bool	Indicates whether a polyline is tappable.
color	Color	Stroke color.
geodesic	bool	Indicates whether to draw each segment of a polyline as a geodesic. The options are true (yes) and false (no).
jointType	JointType	Joint type of all vertices of a polyline, except the start and end vertices.
patterns	List<PatternItem>	Stroke pattern of a polyline. The default value is null, indicating that the stroke pattern is solid.
points	List<LatLng>	Vertexes of a polyline. Line segments are drawn between consecutive points. A polyline is not closed by default. To form a closed polyline, the start and end vertices must be the same.
startCap	Cap	Start vertex of a polyline.
endCap	Cap	End vertex of a polyline.
visible	bool	Indicates whether a polyline is visible.
width	int	Stroke width of a polyline.
zIndex	int	Z-index of a polyline, which indicates the overlapping order of the polyline.
onClick	VoidCallback?	Function executed when a polyline is tapped.
