flutter test --tags does not correctly parse boolean selectors #189193
Description
Steps to reproduce
"flutter help test" points to the test package (which flutter test proxies into) which mentions boolean selectors: https://pub.dev/packages/test#tagging-tests
These do not work, no matter how I've tried (different terminals, platforms, etc) as the tags are unwrapped and/or parsed before proxying to dart, which internally causes the tags to be executed as terminal commands.
- run
flutter test --tags="(golden||ci)"
- other permutations such as
"golden||ci"have the same behaviour
Expected results
Tests only run if the test tag evaluates true for "golden" OR "ci"
Actual results
>$ flutter test -x='golden||ci'
