This package provides type stubs for the proto-plus package. It allows you to type check usage of the library with e.g. mypy and will also improve autocomplete in many editors.
This is in no way affiliated with Google.
The stubs were originally created by stubgen, but have seen some manual improvements since then. Further contributions are welcome.
$ pip install proto-plus-stubs
The stubs should be automatically picked up by your editor or typechecker.
