I'm making a navigation app using flutter + google maps for a large estate and there are some roads inside the estate that doesn't appear in google maps but actually exist. I want to know how to add custom roads to google maps and show routes / distance between two points with my added custom roads

I did some researches about this and I found that KML can use to add custom locations/paths to the map. But at this moment google_maps_flutter doesn't support kms layers (maps android sdk support, but not flutter plugin). Is there a way around to implement KML in flutter without official support?

And just to be sure, when I added KML data to my map somehow, when user using navigation feature in my app, does user see the normal navigation route (like I used google maps app, no custom roads) or do I get path using my custom routes?

Thanks.

Just draw roads as polylines like in [this answer](https://stackoverflow.com/a/56736602/6950238). – Andrii Omelchenko Jul 31 '20 at 12:48
@AndriiOmelchenko thanks! polyline is just a line in the map right? If I want to use direction API polyline doesn't count as a road right? – CharukaHS Jul 31 '20 at 15:07
Yes, you're totally right. – Andrii Omelchenko Jul 31 '20 at 16:04
