[Skia desktop / other platforms] Add a Barcode XAML element to UNO

[booskander]

What would you like to be added? 💡

Syncfusion was looking for a XAML element of a barcode, the one they are using only works with native windows apps and is not supported with a Skia head, I have implemented a workaround solution using ZXing.NET library which is available at https://www.nuget.org/packages/zxing.Net/ and works pretty consistently with dotnet apps. If we could create our own UI element based on that it would be great!

example of output would be something like this:

I simply populate an element with the barcode using SKBitmap.Bytes and assign it to the image source after component initialization

Why is this needed? 🤔

Transferring to Toolkit as this wouldn't be included in core Uno.

If a viable option already exists using third-party libraries, this should be considered low priority

[Xiaoy312]

this would be a pretty low-effect task: displaying a generated image
the problem is if we were to publish this from toolkit, we would have to take dependency on 3rd party library that no one else uses/rarely used, and maintain it for the future
would be better to give the ship code to the user directly, rather that including it here
