2023/07/02 20:13:20 [ERROR] fatal: please update version of ffigen in your dev_dependencies. (version >=8.0.0, <9.0.0)

Start by rerunning the documented flutter_rust_bridge_codegen command and inspect the Flutter project's dev_dependencies, especially the ffigen entry named in the error. Confirm that the configured ffigen version satisfies the reported >=8.0.0 and <9.0.0 range, then rerun code generation and verify it completes without the fatal error.
