[iOS] Flutter 2.8, fine frame drop detected in native listview on iOS. #95838
Description
Flutter 2.8, fine frame drop detected in native listview on iOS.
This is normal in flutter 2.5.
Create a listview with about 200 items.. If you scroll slowly and smoothly at a constant speed, you may find it stuttering.
