[BUG] Microsoft.Maui.Platform.HandlerNotFoundException #140

Open flipper09112 opened 2 years ago

flipper09112 commented 2 years ago

Description I got this error when try open a page with skia:SKLottieView Microsoft.Maui.Platform.HandlerNotFoundException: 'Handler not found for view SkiaSharp.Views.Maui.Controls.SKCanvasView.'

Code I initialize Skia like documentation said

 var builder = MauiApp.CreateBuilder();
        builder
            .UseMauiApp<App>()
            .UseMauiCommunityToolkit()
            .UseSkiaSharp()
            .ConfigureFonts(fonts =>
            {
                fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
                fonts.AddFont("OpenSans-Semibold.ttf", "OpenSansSemibold");
                fonts.AddFont("arista_pro_bold.ttf", "AristaProBold");
                fonts.AddFont("arista_pro_light.ttf", "AristaProLight");
            });

I have this to show lottie

<skia:SKLottieView
            Grid.Row="1"
            RepeatCount="-1"
            Source="ic_trophy.json"
            HeightRequest="300"
            WidthRequest="300"/>

Check if you are missing the following NuGet: SkiaSharp.Views.Maui

Is this still happening in the latest release? I think the maui package was installed as I see the UseSkiaSharp in the program. But I have been testing now and I have not had any issues.
