Current Behavior

When the snackbar is activated, instead of appearing at the bottom, it appears at the top, cutting off a portion of the panel.

Expected Behavior

When activated, the snackbar should be displayed at the bottom.

Steps To Reproduce

Below is the code snippet:

SnackbarOptions snackbarOptions = new SnackbarOptions();
snackbarOptions.BackgroundColor = RSColors.WarningPalette[90];
snackbarOptions.TextColor = RSColors.WarningPalette[20];
await AppBase.Current.MainPage.DisplaySnackbar("teste", null, "Fechar", null, snackbarOptions, default);

Bug reproduction

We always request a reproduction sample, and that's not to make your life hard or anything like that... The reason of having a reproduction is to save us time to indentify and fix the bug. Create a new project; download the MCT NuGet; write UI; ViewModel; create a service; run it. As you can see it's a lot of timing consuming for us that we could spend fixing the actual issue. So PLEASE create a small reproduction project, upload it on GitHub or GitLab and paste the link in the issue.

We don't accept .zip files as reproduction samples, for security reasons. So if you send us a .zip file we will kindly ask you to upload it to GitHub or GitLab and share the link And most important: Please, help us to help you ❤️

Ok, I get it. Sorry, this is my first interaction, so I'm still learning. I found the bug, it happens in the extension:

public static Task DisplaySnackbar(this VisualElement? visualElement, string message, Action? action = null, string actionButtonText = "OK", TimeSpan? duration = null, SnackbarOptions? visualOptions = null, CancellationToken token = default(CancellationToken))
{
return Snackbar.Make(message, action, actionButtonText, duration, visualOptions, visualElement).Show(token);
}

When I used the snackbar directly passing the anchor as null, it worked perfectly.
