strokeCap property

StrokeCap strokeCap
final

Applies stroke cap to the start and end of all polylines. You can set StrokeCap.round to get a semi-circle or StrokeCap.square to get a semi-square at the edges of the polyline.

The default value is StrokeCap.butt which doesn't apply any cap at the ends.
