Looks like the devtools checks started failing here: https://github.com/flutter/devtools/actions/runs/14113668833

Logs are complaining about vm_services_proto, which it looks like it was updated recently around when the failures started.

It looks like the Perfetto protobufs were regenerated in https://dart.googlesource.com/sdk/+/d1bfa65eb4027fa4406947a372b7de3afc093b6c

The updated protobuf classes are using the private _clearField method, which was introduced in Dart protobufs by google/protobuf.dart@b761358
