I'm attempting to update the codelabs for Flutter 3.10 and Dart 3, but I'm hitting a ffigen code generation issue. On attempting to build step_06 of the updated codelab, I'm seeing the following error logs:
In file included from /Users/brettmorgan/Documents/GitHub/codelabs/ffigen_codelab/step_06/macos/Classes/duktape.c:3:
