I think flutter is emerging as a compelling alternative for cross platform desktop development. I’m building a desktop app in it now and so far the experience has been quite positive.
Flutter is also mobile-skewed unfortunately, putting it in the same camp as WinUI if you need more classical desktop widgets. Third party widgets can fill this hole in some cases, but for me that defeats much of the point of using a pre-existing UI toolkit…
I believe you. But try selling that to management. And when the language isn't used for any of the other software maintained by the company and nobody is going to be given time to learn it to keep the knowledge in-house... forget it.
