The only supported way to build Dart is https://github.com/dart-lang/sdk/wiki/Building.

Building purely from sources is tricky and not a currently supported use case. In your case, you'd need to get a version of depot_tools into your PATH and get the sources with fetch dart (depot_tools will provide fetch which will prepare a gclient solution and sync it which will provide the missing buildtools/gn).

Some related issues to bootstrapping from source (though this is probably easier because Arch is glibc-based):
#51788
#51642
