描述

Description

When quickly scrolling the sectionList component, you will notice that the stickySectionHeader displays an incorrect component before switching to another one. In the seventh second of the ios video, you can see that during the fast scrolling, the sticky header changes from section 7 to section 1, then back to section 6. This issue occurs on both Android and iOS.

Steps to reproduce
  1. install the application
  2. cd ReproducerApp and run npm ci
  3. npx react-native run-ios or npx react-native run-android
  4. then quickly scroll up and down the sectionList component.

调研方向

从 bug-sticky-header 分支上的必需 ReproducerApp 开始:运行 npm ci,然后运行 npx react-native run-ios 或 npx react-native run-android。在 SectionList 中复现快速滚动,并检查两个平台上的 stickySectionHeader 行为。完成标准是 sticky header 在快速滚动期间始终显示正确的 section。
