Because of the serious performance regression that was introduced with iOS 16.6 (#131319), a one-time special hotfix was made for the older release 3.10.6 even though a newer stable release was available (3.13.0). While it is recommended that most users upgrade to the newest release on their current channel via flutter upgrade, for users who cannot upgrade their Flutter version for other reasons, can issue the following terminal commands in their Flutter SDK checkout:

git fetch --tags
git checkout 3.10.7
flutter --version
