#0      UnmodifiableListMixin.addAll (dart:_internal/list.dart:129:5)

We need to revert the dart-lang/native in DEPS.

• Unsupported operation: Cannot add to an unmodifiable list in build.dart scripts native#168

[dcharkes]

Oh, actually it didn't roll into Dart yet via DEPS, it's the resolution via pub because we have a published version, let me retract the published version on pub.

[dcharkes]

I think this should cycle green again with the bad version retracted.

Thanks for reporting @sstrickl !
