Looks like some failures during #include of a perfetto header, mostly like:

In file included from ../../flutter/third_party/perfetto/include/perfetto/base/export.h:20:
../../flutter/third_party/perfetto/include/perfetto/base/build_config.h:142:10: fatal error: 'perfetto_build_flags.h' file not found
  142 | #include "perfetto_build_flags.h"  // no-include-violation-check
      |          ^~~~~~~~~~~~~~~~~~~~~~~~
1 error generated.

perfetto_build_flags.h is a generated file located at $root_gen_dir/$perfetto_root_path/build_config.

Looks like I need to patch the Dart SDK to perfetto config to update the include dir.
