Fix Failing Favorites Message #4
Description
The "Added Favorite" message fires inconsistently on this project, especially after the 2nd item.
Fix is to update packages.
Update packages on all projects from
<PackageReference Include="Xamarin.Forms" Version="4.4.0.991265" /> <PackageReference Include="Xamarin.Essentials" Version="1.3.1" />
to
<PackageReference Include="Xamarin.Forms" Version="4.7.0.1142" /> <PackageReference Include="Xamarin.Essentials" Version="1.5.3.2" />
XAML changes: added "xmlns:viewModels" reference and BindingContext. Also set SwipeView BackgroundColor="Transparent" to fix change with Xamarin.Forms Upgrade.
XAML.cs changes: Fixed a possible null reference exception, and awaited the alert.
