Rolls from Engine -> Framework have been failing on customer tests coming from https://github.com/rrousselGit/provider.git. See failure here: https://cirrus-ci.com/task/6685374529929216?logs=main#L1826

This is due to changes in the dart sdk that have upgraded some info diagnostics to warning diagnostics: https://dart-review.googlesource.com/c/sdk/+/283400

We need to do the following:

1. Revert the dart SDK rolls to unblock the engine -> framework roll
2. Revert the analzyer change so that subsequent dart sdk -> engine rolls don't break downstream
3. Fix the customer test
