何やらエラーが出たが、Flutterをローカルで編集した覚えはなかったので無視して”–force”をつけて実行したら無事アップデート完了。

>flutter --version
2.0.6
>dart --version
2.12.3
>flutter upgrade
Your flutter checkout has local changes that would be erased by upgrading. If you want to keep these changes, it is recommended that you stash them via "git
stash" or else commit the changes to a local branch. If it is okay to remove local changes, then re-run this command with --force.
>flutter upgrade --force
success
>flutter --version
2.2.1
>dart --version
2.13.1
