Did a brief search on the rust ffi, seems that mozilla has something interesting shared on the topic https://github.com/mozilla/uniffi-rs and https://blog.mozilla.org/data/2022/01/31/this-week-in-glean-...

I've worked on some projects (private and commercial) where embedding Rust into one of those targets was required: iOS, Android, Flutter, macOS, Web. I've played around with a variety of approaches because there exist multiple solutions depending on the platform. Apart from Web/Wasm, where Rust really shines, the next best solution is uniffi by Mozilla, which has quite solid iOS/Android support: https://github.com/mozilla/uniffi-rs While this works, the bigger pain (at least on iOS) is that the Rust-Compiler LLVM and Xcode LLVM are not always in sync leading to strange bugs. Also, packaging Rust libraries into a nice XCFramework (or even SPM Module) works, but usually involves hacky shell scripts. The reason why you'd still want to do this is if there's a Rust library that has no equivalent on the Kotlin or Swift side. There're a lot of g

ood crates / libraries for Rust would require an expensive re-implementation in Swift or Kotlin. Also, because Rust doesn't have a garbage collector, it is easier to embed in garbage collected languages like Kotlin without running into situations where the two garbage collectors don't agree.

I think they should give up on Flutter for Web and just focus on mobile and desktop (and maybe extend use on Smart Watches, Smart TV, embedded instead). Too many people still remember Java Applets, google's GWT, Flash/Flex and how it ended. They are out of focus trying to support Web as well. I had also higher expectation regarding Dart FFI - I think with their ffigen we are still only in ctypes like python bindings territory. Nowhere near something like pybind11 [0] for c++ bindings yet.
