flutter pub publish: Could not find an option named "dry-run"

Question

When publishing a pub package, the docs say to run the following command:

 flutter pub publish --dry-run

However, this is giving the following error:

Could not find an option named "dry-run".

Run 'flutter -h' (or 'flutter -h') for available flutter commands and options.

How do I run a "dry-run"?
