描述

Description

On android, overriding updateState appears to be the only way to pass information to shadow nodes (which I need for the library port I am working on). This works fine on RN 0.81.1 (used in the prior link), but on RN 0.83.1, the function is never called (see reproducer link).

Steps to reproduce
  1. npm install
  2. npm run android
  3. Notice the square is green not red
  4. Optionally, set a breakpoint at android/app/src/main/java/com/updatestatebug/SampleViewManager.kt:33, and notice it is never hit
React Native Version

0.83.1

Affected Platforms

Runtime - Android

Areas

Fabric - The New Renderer

调研方向

从必需的复现程序开始,运行 npm install,然后运行 npm run android。检查 android/app/src/main/java/com/updatestatebug/SampleViewManager.kt:33,以及 React Native 0.83.1 Fabric Android 中 ViewManager.updateState() 的路径。只有在能够到达 updateState(),且复现出的正方形为红色而不是绿色时,才算完成。
