In this last file named contrat.pbgrpc.dart, the annotation
@$pb.GrpcServiceName is not recognized
As $pb is a reference on protobuf.dart, it seems to create this ticket on protobuf github rather than grpc github

Interestingly enough, I see protobuf: ^2.1.0 in the first comment, but we just recently published 3.0.0; I would have thought this issue was from the 3.0.0 version just from the timing.

Ah - this is likely a dup of #844.
