Code Review
This pull request adds a regression test to ensure that CupertinoDesktopTextSelectionToolbar does not crash when rendered in a zero-sized area. However, the test as written does not correctly simulate this condition. I've provided a suggestion to fix the test implementation so it accurately covers the scenario described in the associated issue.

The test name is 'CupertinoDesktopTextSelectionToolbar renders at zero area', but the current implementation renders the toolbar in the full screen area provided by the test environment, not a zero-sized area. To correctly test this scenario and prevent future regressions for the issue mentioned in the PR description, the toolbar should be rendered within a zero-sized widget like SizedBox.shrink().
await tester.pumpWidget(
CupertinoApp(
home: Center(
child: SizedBox.shrink(
child: CupertinoDesktopTextSelectionToolbar(
anchor: const Offset(10, 10),
children: const <Widget>[Text('X')],
),
),
),
),
);
