null-loader has webpack as a peerDependency.
Therefore vue-cli-plugin-vuetify should either provide webpack itself or also declare it as a peerDependency.
Yarn (berry) will notify the user about this:
➤ YN0002: │ vue-cli-plugin-vuetify@npm:2.4.6 [4afbd] doesn't provide webpack (pb29af), requested by null-loader
Just copying this from null-loader's package.json into yours would remove the message for consumers.

If the consumer project doesn't depend on webpack then yarn will notify about that instead.
When the notice is about the current workspace the user can actually do something about it. (without forking)
