Please, is there someone to explain me why this check was unsuccessful ?

[fzyzcjy]

Click the "Details" button and we can see error logs. Looks like the codegen is not run. Thus try

cargo run --manifest-path /path/to/flutter_rust_bridge/frb_codegen/Cargo.toml -- generate

on frb_example/integrate_third_party folder

I would like to add a simple check that [#2178] is correctly fixed. How do you suggest doing that ?

[fzyzcjy]

Since that issue happens in realworld (web audio api), the simplest way may be: Just copycode into frb_example/integrate_third_party, including the code that causes the problem (iirc it is default_dart_async: false in flutter_rust_bridge.yaml). Then, since CI auto execute codegen tests etc on that example, we automatically ensure it works.
