【Android】：Animated.event does not update latest contentOffset.y on onScroll Event When useNativeDriver is set to true #52657
Description
Description
I want to implement a stickyHeader component that relies on the scroll event of the scrollView to get the latest contentOffset.y. Then, by listening to the changes in y, I can set the translateY property of the stickyHeader.
However, when the content height of the scrollView changes dynamically, especially when it decreases, using addListener to track the animation value changes, we find that when useNativeDriver is set to true, Animated.event sometimes fails to update the latest contentOffset.y value. The listener callback of Animated.event prints e.nativeEvent.contentOffset.y as the latest value, but printing animatedValue.__getValue still shows the previous value.
Unfortunately, we cannot trigger the animation value change in the listener callback of Animated.event, as that would cause the sticky animation to flicker.
Steps to reproduce
- Install the app.
- Click on tab1 and scroll the scroll-view content to the bottom.
- Click on tab2.
- Repeat steps 2 and 3 to reproduce the issue.
I cannot reproduce the issue in the emulator; it only occurs sporadically on a real device.

Is this a New Architecture regression?
yandadaFreedom commentedon Jul 17, 2025
this appears to be related to New Architecture. The issue occurs on Android where newArchEnabled: true, but I haven't tested extensively on the old architecture yet.
