Description
Executing dart run ffigen got the following error:
Unhandled exception:

I checked my Flutter environment:
❯ file /Users/bruce/dev_tools/flutter/bin/cache/dart-sdk/bin/dart
/Users/bruce/dev_tools/flutter/bin/cache/dart-sdk/bin/dart: Mach-O 64-bit executable x86_64
When I run brew install llvm to install llvm, what I get is a library for arm64, which I think is causing the error:
❯ lipo -info /Users/bruce/homebrew/Cellar/llvm/13.0.1_1/lib/libclang.dylib
Non-fat file: /Users/bruce/homebrew/Cellar/llvm/13.0.1_1/lib/libclang.dylib is architecture: arm64
It seems that the Flutter SDK does not have a version for Apple Silicon, so how to solve this problem?
