Description

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

Piste de recherche

Commencez avec le reproducer KeyboardAvoidingViewExample lié et reproduisez le blocage sur iOS avec React Native 0.73.4, en utilisant un KeyboardAvoidingView dans un ScrollView. Examinez l’interaction entre KeyboardAvoidingView et ScrollView autour des callbacks répétées de UIManager.configureNextLayoutAnimation, et comparez le comportement avec React Native 0.72.9. Le travail est terminé lorsque le masquage du clavier ne bloque plus l’application et n’accumule plus de callbacks en attente.
