There are basically two approaches to execute the code generator. The first and most evident approach is to directly execute the
flutter_rust_bridge in command line.
The second approach is to integrate it into
build.rs of your project. With this approach, the code generator is automatically triggered whenever you build your Rust project. For example configuration, have a look at this build.rs file.
build.rs in the example projects is making it difficult to modify and test flutter_rust_bridge_codegen, you can rename it to disable it, and instead use the pure_dart and pure_dart_multi tests to debug any issues. Please refer to
frb_codegen/src/main.rs's tests for more details.
