Code Review
This pull request correctly fixes an issue with gesture local positions in SliverMainAxisGroup and SliverCrossAxisGroup by providing the necessary paintOffset during hit testing. The changes are straightforward and well-implemented. Additionally, the new regression tests are comprehensive, covering various axes, scroll directions, and scrolling scenarios, which ensures the fix is robust. The code quality is excellent, and I have no further suggestions for improvement.

LGTM 👍 . Good catch! We have missed offsets like this elsewhere in the codebase before.
