Layout Transition Not Working When Removing Last Element in a FlatList

[ralph1233]

Description

I tried this example: https://snack.expo.dev/@saad-bashar/remove-item-flatlist
from this article:
https://dev.to/saadbashar/remove-item-with-animation-in-a-horizontal-flatlist-in-react-native-o26

But instead of using Card from react-native-paper, I used a regular View.

On iOS, the layout animation works for both opacity and transition, but when removing the last index, only the opacity works."

Steps to reproduce

When you tap the last index in the list (not necessarily the last remaining item), notice the behavior.

Hi @ralph1233 , I’d like to take up this issue for investigation and a possible fix.
Could you please assign this to me?
I’ll start by reproducing the issue using the provided Snack and then explore the relevant parts of the FlatList and LayoutAnimation implementation in React Native to identify the cause.

Thanks!
