Code Review
This pull request adds a regression test to ensure that CupertinoListTile does not crash when rendered in a zero-sized environment, addressing a previously reported issue. The added test is well-structured and correctly simulates the problematic scenario. I have suggested a minor enhancement to the test to more closely match the conditions of the original bug report, which involved a leading widget.

This is a good regression test. To better cover the scenario described in the original issue, which was related to calculations involving the leading widget, I suggest also testing the case where a leading widget is present. This will make the test more robust against future regressions related to this part of the layout logic.

I think it puts the chevron in by default? My request was we should expect that the chevron is correctly shrunk.

Do you want me to assert that the size of the CupertinoListTileChevron is zero here?

I think this test is fine since we only want to verify that ListTile has size zero.

- The target widget is wrapped by
Center(or is fullscreen) - The target widget does not have an overlay, or the overlay is tested
- The target widget is expected to have a size of exactly
Size.zero
