I don't know about Rust but Go doesn't.

And probably never will. There are a bunch of projects but they are not very good or complete.

The problem is that "good" requires massive amounts of work that is beyond the capacity of single person / small team of volunteers i.e. typical open source project.

Which is why Flutter (and Electron) are the only reasonable technologies for desktop apps that I see today (and in the future).

They get majority of investment from other place: 99.99999% investment in Electron is investment in Chrome.

99% investment in Flutter Desktop is investment in Flutter Mobile.

Flutter Desktop and Electron will continue to benefit from massive investments in Chrome and Flutter Mobile. No other project building desktop UI can come anywhere close this level of investment.

There is react native. Facebook pays for Android/iOS and Microsoft pays for Windows/macOS.

Sadly no maintained Linux desktop app support.
