[google_maps_flutter] Geodesic Polyline support in iOS

[kattaliraees]

Description

Polylines in iOS are not curved based on the earth's curvature even if we set geodesic true in flutter dart code. This is because this property passed to the plugin native code isn't used. I have set this property after GMSPolyline Objc instance created

@ditman I have signed the CLA in Mar 2020. No idea why it's not reflecting.

@kattaliraees There's a couple of commits that seem to come from a different github user than your current one:

• 8741b2e
• 166ec3a

Maybe you can squash them into a commit with your new username and force-push the branch, the system would accept it?

Alternatively, you may be able to start a new branch so you don't have to worry about those two commits?
