The breadcrumb unit test (T-434) pulled package:flutter_test, which imports
dart:ui — unavailable under plain `dart test`. That broke the flutter-free
core batch (ci/test_core.sh) for every file compiled after it. It uses only
package:test APIs, so the import was simply wrong; siblings already use
package:test.
