Hi, I was just trying to ignore some of my golden tests, whose name starts by Golden and decided to use this:

flutter test --name "^(?!Golden).+"

What I receive from the CLI is this instead: Couldn't parse --name "[(?Golden).+]": Invalid group(?Golden).+

Note that the ! from the lookahead is gone.

I've tried to review the code but I can't see any kind of sanitizer process. I've also seen that you're using the args package and I did a quick test of that library without success. It works as expected. So there may be another place where this substitution of the ! is taking place.

Maybe I'm missing something obvious. If you could point me in the right direction I would create a PR in order to fix this.
