Hi @TheCarpetMerchant, thanks for the report! Currently, the flutter downgrade command does not accept a specific version number as an argument.
According to the official documentation, if you want to switch to a specific Flutter version, you should:
Find your desired Flutter version on the Flutter SDK archive.
Navigate to the Flutter SDK path (you can find the path using flutter doctor --verbose):
Use git checkout to switch to your desired Flutter version:
Run flutter doctor to download the corresponding Dart SDK and tools.
That being said, the fact that flutter downgrade silently ignores positional arguments leads to a confusing developer experience. I am keeping this issue open and labeling it as a proposal so the tool team can evaluate either adding support for version arguments, or throwing a clear error message when a user tries to pass one.
