It should be in fact --python_betterproto_opt=pydantic_dataclasses. Someone copied and pasted from tests with wrong prefix. Took me a while to figure out how the plugin system works for protoc. Also, mind that this feature is not yet released, so you need to install from master branch to benefit from this feature.

Ah, sorry, I didn't check and it seems that there are some pre-releases for 2.0: https://pypi.org/project/betterproto/#history
