This auto-formats all *.dart files in the repository outside of the `engine` subdirectory and enforces that these files stay formatted with a presubmit check. **Reviewers:** Please carefully review all the commits except for the one titled "formatted". The "formatted" commit was auto-generated by running `dev/tools/format.sh -a -f`. The other commits were hand-crafted to prepare the repo for the formatting change. I recommend reviewing the commits one-by-one via the "Commits" tab and avoiding Github's "Files changed" tab as it will likely slow down your browser because of the size of this PR. --------- Co-authored-by: Kate Lovett <katelovett@google.com> Co-authored-by: LongCatIsLooong <31859944+LongCatIsLooong@users.noreply.github.com>
