Pass-thru skia context CallerInfo

vvvv gamma question
1

Hi i’m trying to embed skia layer in Avalonia, and everything works correct, however, there is small issue with notifications context, basically my container is something like that:

public partial class SkiaLayerControlWrapper
    : SkiaMediaControlWrapperBase<SkiaLayerControl>,
        IDisposable
{

        // this goes to custom alvalonia drawing operation
        public void SetLayer(Optional<ILayer> layer) => _layer; 
        
        // can't figure out what to do here:
        public void SetNotificationsSource(
        // let's pass notiofications via input pin
        IObservable<INotification> notificationsSource)
        {
                // some resubscription handling

                _notificationsSource.Subscribe(notification =>
                    _layer.Value?.Notify(notification, 
                         /* ops we need caller info here */) 
                ); 
            }
        }
}

So the question is how to get CallerInfo from renderer.

Managed to make it work wia special hook:

However would appreciate tips if there is better approach.

I think you need to pass it internally in your object graph. From AvaloniaLayer upwards.

This might be not so easy to do, since I pass native Avalonia control type everywhere, maybe they have some sort of context object for such scenario need to investigate… Thanks for the point.
