Description
When Animated.Value in styles gets replaced by a constant value, the Animated.Node gets correctly detached, however, the new value is not assigned - the prop gets restored to its default value.
It only happens when using native drivers, when running animation with useNativeDriver: false it works correctly.

Steps to reproduce
Run the code below and press the Animate button. When the animation ends the view snaps to the edge of the screen instead of staying in place.
Snack, code example, screenshot, or link to a repository
import React, {useRef, useState} from 'react';
import {View, Animated, Button} from 'react-native';
export default function App() {
const value = useRef(new Animated.Value(0)).current;
const [useAnimatedValue, setUseAnimatedValue] = useState(false);
function animate() {
value.setValue(0);
setUseAnimatedValue(true);
Animated.spring(value, {
toValue: 1,
bounciness: 3000,
velocity: 0.5,
useNativeDriver: true,
}).start(({finished}) => {
if (finished) {
setUseAnimatedValue(false);
}
});
}
const offset = useAnimatedValue
? value.interpolate({
inputRange: [0, 1],
outputRange: [0, 250],
extrapolate: 'clamp',
})
: 250;
return (
<View style={{flex: 1}}>
<Animated.View
style={{
width: 100,
height: 100,
backgroundColor: 'red',
transform: [{translateX: offset}],
}}
/>
<Button
title="Animate"
onPress={() => {
animate();
}}
/>
</View>
);
