This repo is a demo for a bug issue in react/react-native#15051.
After building and running the React-Native app on iOS or Android from this repo, you'll find some issues:
- The page is not fully loaded at the very beginning. It only renders some parts of rows, and it takes time to fully load those cells.
- The
renderItemcallback in<SectionList/>will be called multiple time for the same cells/rows. - When you scroll the
<SectionList/>on Android devices, it only update a few cells at a time. That's not smooth as on an iOS App and the UX is bad.
