Support

Need help? Create a ticket on our support page for assistance with any issues or questions.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

Probably, this is not that easy if we do not want to keep updating the Flutter FFI with every small change in everything.

I spend a lot of time thinking about this kind of libraries for rust when I was designing lampo, and I think the best way is writing the library in rust as a separate module like arkade-ffi where there is a rust implementation of the API that we want to expose to the user, then use https://pub.dev/packages/flutter_rust_bridge to generate the dart package

An example is https://github.com/vincenzopalazzo/lampo.rs/blob/main/lampo-c-ffi/src/lib.rs

This allow you to keep the type safety of rust because the you need to check only the function parameters, then implement a better error handling that will be lost otherwise (or will be very difficult to keep across ffi channels due the Option vs Exceptions)

[tiero]

my goal wasn't to have a solution for production apps or either merge it, just wanted to have a single place I can point people with Rust & Flutter experience what to look into and how the bindings would look like and ability to start hacking on it.

At the moment we don't have plans to start a native dart library (pending MuSig2 support) or either official Flutter bindings, so I would postpone the decision and leave to external contributor to iterate on it.

Thank you for the insights

I wanted to have a barebone example close to the actual code here, I was not thinking of a full fledged flutter app. Open to proposals to simplify eventually
