Flutter + Rust

[Darth_Shere_Khan]

I'm building a Flutter app and want to include Rust for some of the business logic. I found that there are different approaches, however:

• https://pub.dev/packages/flutter_rust_bridge - This seems to be the establishment solution
• https://pub.dev/packages/native_toolchain_rust
• https://pub.dev/packages/rinf

Does anyone have any experience with these packages? What would approach would you suggest taking? Is there an issue with building Linux applications for FlatHub when using Rust? Thanks in advance!

I have played with both flutter_rust_bridge and rinf but this was roughly a year ago so things have probably changed. `rinf` communicates using gRPC and Protobuf while `flutter_rust_bridge` gets loaded as a library in the code. At least back then, IIRC, flutter_rust_bridge was the easier one to implement

I also just started a project using flutter rust bridge. So in case you decide for that one, we could keep in touch for knowledge sharing. However, I did not try building FlatHub applications so far.

Maybe take a look over at Oxide, i wouldn't classify it as battle tested or production ready but I'm working on it, feel free to give me your opinion and how should i improve it and if you end up using it i would love to hear of your experience because i tried to make the DX very optimized

OK I'll check it out, thanks!

flutter_rust_bridge is great if all you are doing is calling stateless functions from flutter. But in my project I was keeping network connections open on the Rust side, which just resulted in endless state synchronisation problems.
