denis@MacBook-Pro microbenchmarks % dart format .            
Could not format because the source could not be parsed:

It works if i run dart pub get before running format, so we'd probably need to do this before running format in this subfolder, as we do always run in the parent folders.

Looks like dart format is broken. Any reason for continuing to keep main still on the old dart and v9 as a separate branch? I remember there was a discussion about merging v9 to main after a patch release and that was a couple of weeks ago. If we cannot merge yet, just do the workaround you're suggesting and revert after merging v9 to main.

@vaind Thin we can merge v9 soon, just have some PRs open pointing against it. As the fix here, we jsut need to run pub get in the subfolder, then everything works. Created a PR with some other fixes as well.
