How to show SVG string as an Image in Xamarin?

Question

So the simple idea is that I have SVG data as a string that I fetch from Internet. I would like to show that as an icon in my app. Is there any way I can do this?

I have seen countless examples where SVG data is in a file located in the app's directory that is then showed but this is not what I am looking for. I literally have the data in XML format after http request and I only need to transform that to a Image or something else visible on the screen.

I have been trying to find a solution to this for hours now, so I would really appreciate some help :S

Thanks for the recommendation @Jason ! SvgImageSource.FromSvgString did the trick really well. Great point in this method is also that you can first make changes to your string before you actually pass it forward (for example change colors etc). — BladeZ

Android doesn't support svg with ImageView directly,you could display SVG with some commonly used third-party controls.

Like FFImageLoading.

Add Xamarin.FFImageLoading.Svg nuget package to platform project. Use ImageService with svg data resolver for displaying svg images.

For Android:

<ImageView
    android:id="@+id/image_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

then use like:

var svgString = @"<svg><rect width=""30"" height=""30"" style=""fill:blue"" /></svg>";
ImageView imageView = FindViewById<ImageView>(Resource.Id.image_view);
ImageService.Instance
    .LoadString(svgString)
    .LoadingPlaceholder(placeHolderPath)
    .WithCustomDataResolver(new SvgDataResolver(64, 0, true))
    .WithCustomLoadingPlaceholderDataResolver(new SvgDataResolver(64, 0, true))
    .Into(imageView);

Thanks for help! I ended up using this exact library after I continued my research the next day. I used SvgImageSource.FromSvgString in my final solution.
