Code Review
This pull request introduces the scrollCacheExtent property to AnimatedList, AnimatedGrid, and NestedScrollView widgets, allowing for control over the cache extent of their underlying scroll views. The changes involve adding the scrollCacheExtent parameter to the constructors of these widgets and their internal components, ensuring it is correctly passed down to the RenderViewport. Corresponding tests have been added for AnimatedGrid, AnimatedList, and NestedScrollView to verify this functionality. The review comments suggest improving the test code in nested_scroll_view_test.dart by using tester.renderObject for better readability and adherence to common testing practices.
