Riccardo CipolleschiandFabrizio Cucci	8207a09107	Fix images not displayed when extension is implicit (#48888 ) Summary: Pull Request resolved: https://github.com/facebook/react-native/pull/48888 We have a report from OSS where Images are not displayed properly in case they are saved on disk with no extension. We previously had a fix attempt iwith [this pr](https://github.com/facebook/react-native/pull/46971), but this was breaking some internal apps. This second attempt should work for both cases. ## Changelog: [iOS][Fixed] - Load images even when the extension is implicit Reviewed By: cortinico Differential Revision: D68555813 fbshipit-source-id: bc25970aafe3e6e5284163b663d36e00b3df3d82	2025-01-27 14:59:35 +00:00

Tim YungandFabrizio Cucci	3abb4cab7d	Animated: Defer `onAnimatedValueUpdate` on Attach + Native (#48715 ) Summary: Pull Request resolved: https://github.com/facebook/react-native/pull/48715 {D68154908} fixed a problem with the `onAnimatedValueUpdate` listener not being correctly attached if `__attach` were called before `__makeNative` (which sets `__isNative` to true). We're potentially seeing production symptoms of stuttering interactions and user responsiveness, after queuing up many operations. Our hypothesis is that in scenarios where `ensureUpdateSubscriptionExists` is being called during `__makeNative` (instead of during `__attach`), a backup of operations occurs leading to these symptoms. This diff attempts to validate and mitigate this hypothesis by deferring `ensureUpdateSubscriptionExists` to when an `AnimatedValue` instance has had both `__attach` and `__makeNative` invoked. Changelog: [Internal] Differential Revision: D68236594 fbshipit-source-id: 2089100a773ebfc161fb5b567123eb58a893939f	2025-01-20 15:08:03 +00:00
Tim YungandFabrizio Cucci	bb5f971389	Animated: Fix `onUserDrivenAnimationEnded` w/ Insertion Effects (#48678 ) Summary: Pull Request resolved: https://github.com/facebook/react-native/pull/48678 While diagnosing a recent issue in which `AnimatedValue` instances were not being correctly updated as expected, the insertion effects feature flag was identified as a root cause. Upon further investigation, it appears that this is because the `onUserDrivenAnimationEnded` listener was not implemented the same way in the two feature flag states: - When `useInsertionEffectsForAnimations` is disabled, `useAnimatedProps` listens to `onUserDrivenAnimationEnded` in a passive effect, after all nodes have been attached. - When `useInsertionEffectsForAnimations` is enabled, `useAnimatedProps` listens to `onUserDrivenAnimationEnded` in an insertion effect when attaching nodes. The bugs occurs because `useAnimatedProps` checks whether native driver is employed to decide whether to listen to `onUserDrivenAnimationEnded`. However, we do not know whether native driver will be employed during the insertion effect. (Actually, we do not necessarily know that in a passive effect, either... but that is a separate matter.) This fixes the bug when that occurs when `useInsertionEffectsForAnimations` is enabled, by moving the listening logic of `onUserDrivenAnimationEnded` into a passive effect. This is the same way that it is implemented when `useInsertionEffectsForAnimations` is disabled.
