説明

Description

When KeyboardAvoidingView inside a ScrollView and focus a TextInput the app crashes (goes extremely slow).

This seems to only happen if the KeyboardAvoidingView needs to trigger the animation, if the ScrollView is small it works fine.

Testing with react native 0.72.9 the issue doesn't seem to happen

Steps to reproduce
  1. install the app yarn ios
  2. Using the simulator make sure the keyboard shows when entering a text input
  3. Focus a text input and start typing on the keyboard
  4. Dismiss the keyboard / click outside of the input
  5. You will notice the app has now hung
React Native Version

0.73.4

調査の方向性

リンクされた KeyboardAvoidingViewExample の再現ケースから始め、ScrollView 内で KeyboardAvoidingView を使用して、React Native 0.73.4 の iOS でハングを再現します。繰り返し発生する UIManager.configureNextLayoutAnimation コールバックの周辺にある KeyboardAvoidingView と ScrollView の相互作用を調査し、React Native 0.72.9 での動作と比較します。キーボードを閉じてもアプリがハングせず、保留中のコールバックが蓄積されなくなれば完了です。
