Could you please attach a small project to reproduce the issue

@sasukevita as mentioned a reproduction project would be super helpful. Thanks!

What I found from the code, that we are not able to get the XF renderer for the VisualElement. If you are not calling the method from XF, I think it won't work.

You call DisplaySnackBarAsync from a page that is not the MainPage. You should do : App.Current.MainPage.DisplaySnackBarAsync( )

I had the same problem and this fixed it
