3D polylines integration

[talghe]

Hello,

I have looked at the api documentation for a long time and I have looked at the example codes of mapbox maps flutter, and I have not found any way to add 3D polylines.
I am not a professional developer and therefore I may have missed something, but I am almost certain it is not yet possible to do this.
As I am integrating flight paths in my app, I absolutely need this feature.

I have found out that Point Annotation manager has a possibility to Offset in the Z direction, and also the Polyline Annotation Manager but it Offsets all the polyline and I would need to add altitude to each point individually.
The Polyline Annotation Manager takes the Polyline Annotation Options, which has geometry that takes a Line String with coordinates that takes a list of Positions. Position has the ability to take a 3rd argument which is the altitude, but when adding the altitude, the created Polyline has only 2 items instead of 3 in each Position's point. These 2 items are the latitude and altitude.... instead of longitude and latitude, and potentially the altitude in a 3rd item but that is not working currently.

Hope there is a solution for that, or that you will be able to add this in a short time.

Thank you in advance!
