Rust matrix-sdk-crypto
element-android is actively working on swapping their crypto layer to the matrix-rust-sdk one: https://github.com/vector-im/element-android/issues/3644
in other news, element ios seems to be enthusiastic about the rust-sdk crypto layer
though, they don't have public issues about that yet.
In terms of bindings this randomly popped up, haven't looked at it yet: https://www.reddit.com/r/rust/comments/ncc9vc/rid_integrate_rust_into_your_dart_or_flutter_app/
There's also a lot of consideration happening around sane FFI
one of these days we'll end up with a one true binding generation lib that will use those macros like rid/wasm-bindgen/pyo3
