Describe the bug
We make use of flutter_rust_bridge version 1.82.6. For reasons as of yet unknown, code generation stopped working with this error message:
An error occurred: Nothing is generated for dart wire class. Maybe you forget to put code like mod the_generated_bridge_code; to your lib.rs?
Steps to reproduce
- Possibly relevant that I run Rust 1.83 on Arch Linux (btw)?
git clone git@github.com:MinBZK/nl-wallet.gitcd nl-walletcargo run --manifest-path wallet_core/flutter_rust_bridge_codegen/Cargo.toml- Observe error (see logs below)

welcome commented
Hi! Thanks for opening your first issue here! 😄
rubin55 commented
Note: I tried downgrading to rust 1.82, but while I did note the resulting binary running for a noticably longer time, the error message remains the same.
fzyzcjy commented
We make use of flutter_rust_bridge version 1.82.6
Firstly, compared to v1, v2 is much stronger, and thus I strongly suggest to upgrade to v2 :)
code generation stopped working
Since code generation did work before, I guess one approach is to bisect the environment. For example, ffigen version, etc.
rubin55 commented
Is there a way to get more verbose messaging? I did execute with RUST_LOG=debug, but it doesn't show any additional messages that give me a hint as to where the problem originates.
With regards to upgrading to v2, believe me, it's on the todo but not something we can do as-of-yet.
fzyzcjy commented
You can try to run frb by source code (cargo run ...), and then can add arbitrarily many println! here and there for debugging.
The v1 code is in: https://github.com/fzyzcjy/flutter_rust_bridge/tree/v1-master
