Unable to find stdlib.h when closely following example app.

Hey,

I'm closely following the example app, with a go directory and hook/build.dart that is identical to the example app apart from a single Go function I added to test out the functionality, and I've tried everything I can think of to get this to build successfully without success. I have zero experience with c... I've been trying to avoid it for the 10 years I've done this... and I've tried everything I can think of.

For what it's worth, I'm on an M1 macbook pro. The package would be amazing if I can get it to work... I spent all night last night working offline, trying to write a script that would compile Go to the various architectures and operating systems, and wound up with some jumbled mess that I was scared to touch so I didn't break it.

Launching lib/main.dart on macOS in debug mode...
