Thanks!

Would be good to also mention in the commit message that the protoc_plugin version is updated.

(I think generated files should mention the protoc_plugin version used, but we don't do it yet.)

Hm, this seems to be a breaking change with createRepeated removed, as this is exposed in the public API.

[osa1]

Good catch. Yes, that's expected, if the protos are exposed we should bump the major version.

In the changelog we can mention that users should use <Message>[] instead of Message.createRepeated(). (same as protoc_plugin changelog entry for the change: https://github.com/google/protobuf.dart/blob/master/protoc_plugin/CHANGELOG.md)

@mosuem I also just noticed that the current version has the minimum protobuf bound of 5.0.0, but 5.0.0 has a bug, see the last entry here: https://github.com/google/protobuf.dart/blob/master/protobuf/CHANGELOG.md#510

We should also update it to 5.1.0 to make sure users will use at least 5.1.0 or newer and have the bug fix.

I am wondering why the protos are exposed at all. I think they shouldn't be. I will try to remove the export, which is breaking in itself - I think I added them a while back for some g3 error. Let's see.
