Description

Lottie animations inside the EmptyView of a CollectionView will not render, but will render normally inside ItemTemplate. I've not tested this issue on ListView or CarouselView.

Examples:
Android - Empty array as source:
Screenshot_1716213126

Android - Array with 3 items as source:
Screenshot_1716213145

iOS - Empty array as source:
Simulator Screenshot - iPhone 15 - 2024-05-20 at 14 53 21

iOS - Array with 3 items as source:
Simulator Screenshot - iPhone 15 - 2024-05-20 at 14 53 37

Steps to Reproduce

  1. Create a new .Net MAUI App using the standard Visual Studio template.
  2. Add the Nuget package SkiaSharp.Extended.UI.Maui to the project.
  3. Add a lottie json file to the Resources>Raw folder. In my case I downloaded any example file from http://lottiefiles.com/. My sample is attached lottie.json
  4. Replace the MainPage.xaml content with from the following code, adding the specific namespace declaration xmlns:skia="clr-namespace:SkiaSharp.Extended.UI.Controls;assembly=SkiaSharp.Extended.UI" at the top, and renaming the lottie file name to the name of the file added to the project/solution.
    <CollectionView>

        <CollectionView.ItemsSource>
            <x:Array Type="{Type x:String}">
                <!--<x:String>lottie.json</x:String>
                <x:String>lottie.json</x:String>
                <x:String>lottie.json</x:String>-->
            </x:Array>
        </CollectionView.ItemsSource>

        <CollectionView.EmptyView>

            <Border HeightRequest="100">

                <skia:SKLottieView
                    RepeatCount="-1"
                    RepeatMode="Reverse"
                    Source="lottie.json" />

            </Border>

        </CollectionView.EmptyView>

        <CollectionView.ItemTemplate>

            <DataTemplate>

                <Border HeightRequest="100">

                    <skia:SKLottieView
                        RepeatCount="-1"
                        RepeatMode="Reverse"
                        Source="lottie.json" />

                </Border>

            </DataTemplate>

        </CollectionView.ItemTemplate>
    </CollectionView>
  1. Run the project and notice that the ItemsSource is set to an empty array and that the lottie animation won't be rendered in the app (on either iOS or Android).
  2. Uncomment the ItemsSource items so that ItemsSource is set to an array with three items (below), and run the application again to see the animations will render in the app.
     <CollectionView.ItemsSource>
          <x:Array Type="{Type x:String}">
              <x:String>lottie.json</x:String>
              <x:String>lottie.json</x:String>
              <x:String>lottie.json</x:String>
          </x:Array>
      </CollectionView.ItemsSource>

I was able to partially reproduce the sample

AppMAUI.zip

lottie.json was not rendered

When removing lotti.json and uncommenting

            <x:Array Type="{Type x:String}">
                <!--<x:String>lottie.json</x:String>
                <x:String>lottie.json</x:String>
                <x:String>lottie.json</x:String>-->
            </x:Array>

Exception happens both iOS and Android:
