Xamarin Forms Maps - how to refresh/update the map - CustomMap Renderer

Question

If you are searching for a full polylines, pins, tiles, UIOptions (and 3D effects soon) renderings/implementations, you should take a loot at the public github I made at

Answer 1

So after lot of searches and, of course, the answer of @Sven-Michael Stübe, you can have your proper maps which works on each platform "Android, iOS, WinPhone". Follow my code, then edit it following the @Sven-Michael Stübe's answer.

Once you finished everything, it could works (like for @Sven-Michael Stübe), but it also couldn't work (like for me). If it doesn't works, try to change the following code:

public static readonly BindableProperty RouteCoordinatesProperty =
    BindableProperty.Create>(
        p => p.RouteCoordinates, new List());

by

public static readonly BindableProperty RouteCoordinatesProperty =
    BindableProperty.Create(nameof(RouteCoordinates), typeof(List), typeof(CustomMap), new List(), BindingMode.TwoWay);

See the documentation for more information about it. (Deprecated implementation)

Then the code works !

PS: You can have some troubles with the polyline at the end, which not following the road right, I'm working on it.

PS2: I'll also make a video to explain how to code your customMap to don't have to install a NuGet package, to be able to edit everything at the end ! (The first one will be in French, the second in English, this post will be edited when the video will be made)

Thank angain to @Sven-Michael Stübe !! Thank to up his answer as well :)
