Code Review
This pull request adds a widget test for AnimatedList. The test renders an AnimatedList within a zero-sized container to verify it does not crash. My feedback includes a suggestion to initialize the list with one item to ensure the item layout and paint logic is also tested under these conditions.

The current test uses an AnimatedList with the default initialItemCount of 0, which results in an empty list where the itemBuilder is not invoked. To make the test more comprehensive, consider setting initialItemCount to 1. This will ensure that the layout and painting logic for list items are also tested within the zero-sized environment.
Suggested change

| child: SizedBox.shrink(child: AnimatedList(initialItemCount: 1, itemBuilder: (_, i, _) => Text('$i'))), |
