Google maps directions and area near route

问题

How I can do something like here in image with google map, Is anybody know ho to do this.

So here is directions and area near route directions (green opacity area)

回答1:

I would approach this by using the Directions API and getting lat/lng of each step.

I would then use the Polygons API to draw circles of a chosen radius, every x meters along a straight path following the steps.

EDIT:

A better solution would be to use the steps with a Polyline, and give it a sufficiently thick strokeWidth
