According to the spec, the expression inside a relational pattern is `bitwiseOrExpression`. We were only allowing `shiftExpression`. Bug: https://github.com/dart-lang/sdk/issues/50035 Change-Id: Ie1a5746f1060b84e6e1b856a622e89db698b4684 Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/292285 Commit-Queue: Paul Berry <paulberry@google.com> Reviewed-by: Konstantin Shcheglov <scheglov@google.com>
