Setting visibility of FlyoutItem to invisible results in a crash

[arnirichard]

I am new to Maui and I need to create an app where tab visibility depends on the user data/rights. So I began to study this sample project.

I made the following change to App.xml: (added x:Name="tabFav" IsVisible="False")

<FlyoutItem Title="Favorites" Icon="tab_favorites.png" x:Name="tabFav" IsVisible="False"> <ShellContent ContentTemplate="{DataTemplate page:FavoritesPage}"/> </FlyoutItem>

and changed in App.xaml.cs:

void TapGestureRecognizer_Tapped(System.Object sender, System.EventArgs e) { Shell.Current.GoToAsync("///settings"); tabFav.IsVisible = !tabFav.IsVisible; }

Setting tabFav to visible works but setting to invisible results in unhandled exception when running app in Windows
