Downgrading from 2 to 1.22 does not work

[ggiuffre]

I would like to temporarily downgrade from Flutter 2 to Flutter 1.22.6, but flutter downgrade only allows to downgrade to 1.20.4.

Steps to Reproduce

1. Make sure to be on the stable channel with Flutter 2.x
2. run flutter downgrade 1.22.6
3. the output should be Downgrade flutter to version 1.20.4 followed by ? [y|n]: n on the next line

Temporary solution that I've used

cd /path/to/flutter-sdk
git checkout 1.22.6

Hi @ggiuffre
This command does not support jumping back to a specific version. There is an opened issue requesting this feature, please follow up on it: #71723.

As a side note, I've just ran this command and my output is quite different.

Thank you

[ggiuffre]

Thank you, @pedromassangocode
