I don't know how to handle 'zoomBy with focus'
You have some ideas?

@andrea689 thanks again for contributing! Could you send me an email? would love to setup collaborator rights for you so you can push directly to this repository.

zoomBy with focus'

zoomBy is zooming with a specific amount of zoom and focus is using a focal point (a x,y position on screen). The iOS SDK will have a functionality available where you can convert a x,y positon on screen to a LatLng, this value together with the zoom can be used to calculate a new camera position.

Note that the concept of zoom on Android is very different than the altitude on the iOS SDK. We will need to find a conversion for it. (I have pinged the Mapbox iOS team for it).

@andrea689 capturing from an iOS engineer working on the maps SDK, you can use:
MGLZoomLevelForAltitude() / MGLAltitudeForZoomLevel(). to convert the value you get from flutter to an altitude expected by the iOS maps SDK API.

@tobrun thanks for the opportunity, I send you an email.
I have already used those methods, my doubt is on the focal point.
On Android there is a method, but on iOS there is nothing that I know.
After conversion of zoom to altitude and set this on camera, how I use focus? Using it as a center of camera is wrong I think.

correct, we can actually opt to not expose. I don't feel this is a highly needed feature. Can you remove it from the flutter and android code?

[tobrun]

@andrea689 was finally able to get my iOS dev. env. working. I had to export SWIFT_VERSION=3 as env. variable. I took this PR for a spin and is already looking good! tiltTo doesn't seem to be doing anything, the zoomBy with focus can be removed.

[andrea689]

@tobrun in the example, tiltTo use the same value of newCameraPosition, so I think you don't see nothing because you has pressed newCameraPosition before tiltTo

@tobrun I used the focal point as a center of camera and seems work as Android! :D
@yoavrofe can review now, thanks!

[tobrun]

@andrea689 would you be able to rebase this branch?

Looks good to me.
