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

The format tests are failing, do you mind taking a look at them and fixing the formatting of your obj-c code?

[kattaliraees]

@ditman Yes. corrected

I took another look at this change, and I think this cannot be merge it as is, sorry it took me a while to notice!

I think you need to remove the geodesic property from the polyline constructor(s) and set the geodesic property of the polyline in the InterpretPolylineOptions static method here, similarly to how visible is being handled.

This change will make it work when adding a Polyline but also would allow your code to toggle geodesic on/off on polylines that are already created.

Can you re-implement this following the same pattern as the "visible" attribute of the polyline? (there's a setVisible method, the InterpretPolylineOptions can handle changes to visible, etc...

[ditman]

Ohh, this is so much simpler now, thank you very much!

Can you rename "GeoDesic" / "geoDesic" to "Geodesic" / "geodesic"?

Other than that, this is great now!

[ditman]

There's one test failing, but it's because this branch hasn't been fully updated with master since last night. I'll merge this right away.

Thanks for your contribution!
