Hmmmm... I'm not getting this to repro locally. Looking at the reported failure, I wonder if this wasn't actually a mis-report?

The test failure was flagging example/pubspec.yaml

which is in fact not sorted:

https://github.com/flutter/packages/blob/837b1a321d3f00034556ef5b385abb93c0843715/packages/animations/example/pubspec.yaml

Whereas we were looking at the root pubspec above (and that seems ok).

🤔

Ah! you are right.

I will file a fix for the animations package.

Sweet!

When I un-revert (and for future reference), is there an easy way for me to test pro-actively if an engine roll would be blocked by a given SDK commit?
