Sure, but that doesn't help if your project is in Rust.

Rust actually has a library with very good flutter integration, it does require using dart for the actual flutter part though, but it works well together.

Are you talking about nativeshell[1] or something else? nativeshell looks to be in early stages of development still.

Sure, there's a whole class of languages that are enough like one another that if you know one you have an advantage picking the other one up.

On the other hand, it looks like Rust is only moderately more popular than Dart: https://www.tiobe.com/tiobe-index/

But I can see why they'd steer away from a language controlled by one company, especially one notorious for killing off projects.
