How do you generate via buf?

[Galaf]

Hello!

I tried generating the base files and it is perfectly OK but I can't generate the gRPC files.
Trying to use something like:

  - plugin: buf.build/protocolbuffers/dart:v21.0.2
    out: "grpc:proto/dart"

will fail with the following error message:

The filename, directory name, or volume label syntax is incorrect.

I tried several variations such as

1. same out but with a comma to separate the options.
2. separate plugin entry with a grpc: prefix.

But it doesn't seem to work anyway.

Thank you in advance for your help.

    out: lib
    opt:
      - grpc
