Code Review
This pull request correctly fixes an assertion failure when accessing RenderBox.size during baseline computation by introducing a _debugDoingBaseline flag. The fix is accompanied by a solid regression test that reproduces the issue and verifies the fix. I've suggested a minor style improvement in the test file to make helper classes private, following the Flutter style guide.
