And for check the version which you Currently used:

flutter --version

Answer 2

If you're seeing the message:

There is no previously recorded version for channel "stable".

Navigate to your Flutter installation folder and run git checkout flutter_version

If you're using snap on Linux and want to downgrade to 1.22.6:

cd $HOME/$USER/snap/flutter/common/flutter
git checkout 1.22.6
flutter --version
