In an upcoming Dart SDK change
(https://dart-review.googlesource.com/c/sdk/+/450970), I intend to add
logic to the analyzer for generating a warning if an API marked
`@experimental` is used. This will allow experimental analyzer features
to be developed without creating a risk of breaking changes downstream.

To prepare for this, release `8.2.0` of the analyzer removes several old
`@experimental` annotations that were out of date. To avoid breaking
trybots, those removals need to roll into flutter before we can land
https://dart-review.googlesource.com/c/sdk/+/450970.
