The point of using Rust with Flutter

Does it make sense to Rust with Flutter? Business logic will be written in Rust and the rest in Dart. I haven't written the code in Dart yet, and before I start I would like to know about this possibility

Will the business logic run in the backend or as a native or WASM module that is shipped as part of the frontend? If you do the former, sure its possible (whether it is sensible depends on your concrete use-case, but I'd say it is about as sensible as using React Native or any other cross-platform framework written for an OOP language). If you do the latter, I have no idea how well Rust and Dart integrate.
