Facing the same issue. @sigurdm any idea?

a14n commented 4 years ago

I face it with any.proto :

protoc --dart_out=grpc:"$OUTPUT" -Iprotos google/protobuf/any.proto

All the versions are up to date:

It looks like it was an issue caused by an issue in dart SDK. I accidentally used the dart SDK packaged with flutter. I was then on Dart VM version: 2.9.0-11.0.dev.flutter-e007545c42 and this version was problematic. Updating the dart SDK fixes the issue.
