I was surprised to learn about SkiaSharp. Isn't Skia what Flutter is built on? I couldn't help imagine how great Flutter would be written in C# rather than Dart.
I actually half built a solution where the Flutter engine was running on Xamarin (hence coded in C#), and got a basic hello world app running. It does have the downfall of slower boot times and larger file sizes though.
But I abandoned it because its too big of a project for a one person side project.
