Is it possible to add another package of pub.dev to use it?
Probably not. As the document said,this package is not another copy of flutter. It has different implementations.
Thank you for answer. By the way, I've been struggling with a Dialog issue for a week now. Could you please tell me what the problem is?

I think it's because you have used material widgets in your code, so you need to wrap your app in a material app.This solution also applies to flutter. I removed your font resources loading and changed your source code to this
