Summary:
D36902220 (https://github.com/facebook/react-native/commit/a04195167bbd8f27c6141c0239a61a345cac5a88) changed Animated to only use value of natively driven nodes on initial render.
However, there remained a case where we could end up with a race condition between Fabric prop update (via SurfaceMountingManager.updateProps) and Animated (via NativeAnimatedNodesManager.runUpdates), when an animation on a node that was created natively is triggered close to render (such as in componentDidUpdate). This happens as Animated and Fabric aren't synchronized, and at the platform level, they do not know each other's state.
Say we have two items, where opacity is used to indicate whether the item is selected. On initial render, A's opacity is set to 1, and animated sets opacity to 1; B's opacity is set to 0, and animated sets opacity to 0. When B is selected (and causes A and B to rerender), A's opacity is now set to null, and animated sets opacity to 0; B's opacity is also now set to null, and animated sets opacity to 1. A's props have changed, and thus the default opacity value of 1 is applied via Fabric, but Animated also sets the opacity to 0 - either may end up being the value visible to the user due to the nondeterministic order of Fabric update props and Animated. This is what is causing T122469354.
This diff addresses this edge case by using the initial prop values for native animated nodes, for subsequent renders, to ensure that values of native animated nodes do not impact rerenders.
This diff also fixes a bug in OCAnimation where translateX/Y values of 0 in transition will result in render props containing translateX/Y instead of transform, resulting in potentially incorrect pressability bounds.

Summary:
D36612758 (https://github.com/facebook/react-native/commit/40f4c662bc7a66e5caea4909d74f435f5b72190c) attempted to remove the check that the animated node was native when fetching animated prop values for render, in order to fix an issue that arises when a node is converted to native before the initial call to render to mount the component, where the initial value is not applied.
However, this causes issues for cases where we call setValue on an animated node soon after render, such as on componentDidUpdate. setValue first updates the animated node value on JS side, then calls the native API setAnimatedNodeValue. The problem is that the next render will then use these updated values in the style props (because we removed the check for native in D36612758 (https://github.com/facebook/react-native/commit/40f4c662bc7a66e5caea4909d74f435f5b72190c)), resulting in a diff in props. Since Animated and Fabric aren't synchronized, there's a race condition between SurfaceMountingManager.updateProps and NativeAnimatedNodesManager.runUpdates
To allow proper rendering of initial values of native animated nodes, and mitigate the issue when calling setValue on an animated node soon after render, during initial render we use the initial values of both native and non-native driven nodes, and on subsequent renders we only use the initial values of non-native driven nodes.
An alternative considered was to add internal state to the nodes themselves (AnimatedProps, AnimatedStyle), but keeping it in sync with the component state is not easy/clean as AnimatedProps can be recreated and reattached at any time for a mounted component.

Summary:
In AnimatedComponent.render, we get the initial values of any styles backed by AnimatedNode, but ONLY for non-native animations. Thus, if convert an animated node to native before the call to render to mount the component, we will end up not applying the initial value until after the component is mounted. This may result in a visible flicker as the expected value is applied some time after the component is mounted and visible.
- Without native driver: BaseViewManager.setTransform called during view preallocation (ViewManager.createViewInstance)
- With native driver: BaseViewManager.setTransform called during MountingManager.updateProps (called from PropsAnimatedNode.updateView)
This diff removes the isNative check in AnimatedStyle and AnimatedProps when traversing style props. This shouldn't be a problem:
- Created as non-native, animated with JS driver
- This diff does not affect this scenario
- Created as non-native, animated with native driver
- Initial value is applied correctly on render/mount. On subsequent renders, the outdated value from JS side will not apply on the platform view as it has not changed.

Summary:
There are use cases of needing to setValue multiple times per second (for example, using PanResponder to update a slider component).
This requires the use of the native driver for perf reasons as using the JS driver will cause a rerender. Currently, the only way to make an animated node native is via setting useNativeDriver: true on an animation config. For example:
```
Animated.timing(animatedValue,
{
toValue: newValue,
duration: 0,
useNativeDriver: true
}).start();
```
To avoid needing to call the above, add a useNativeDriver param to the constructor. When set to true, the node will be made native immediately.
```
const animatedValue = new Animated.Value(0, useNativeDriver);
...
animatedValue.setValue(newValue);
```
Note that, like with useNativeDriver in the animation config, once a node is made native, it cannot be reverted to JS-only.
---
As an aside, PanResponder uses JS-side events, and thus we cannot use Animated.event with native driver; we instead need to setValue on a native AnimatedValue. A much more thorough explanation is in D34564598.

[General][Fixed] - Improved Flow type inference in Animated `.interpolate()`
Improves the ergonomics of `.interpolate()` by allowing Flow to infer the correct type for `outputRange`. This is achieved by adding a new type parameter `OutputT` to `interpolate()` (and `Animated.Interpolation` and `InterpolationConfigType`), which Flow infers as either `number` or `string` based on usage.
Admittedly, at the call site, this is not that much safer compared to something like `outputRange: $ReadOnlyArray<number | string>`, but it does document the intent of the API a bit better and provide some downstream type safety. For example, we can now express `Animated.Number` (D35869375) more precisely by excluding string-valued interpolation nodes.

Summary:
This drastically improves `Animated.interpolate` performance when `inputRange` has a considerable amount of elements (~100 in my tests).
For instance in `ActivityIndicator` inside `react-native-paper`, the input has 144 elements https://github.com/callstack/react-native-paper/blob/main/src/components/ActivityIndicator.tsx#L170. `react-native-elements` has 9k stars, so I'm assuming this is widely used.
### Cause
The reason for the performance drop is that if we assume `n` to be the size of the range, calculating `'inputRange must be monotonically non-decreasing ' + arr` essentially calculates `arr.toString()` which has O(n) complexity.
Since it is recalculated in a for loop, we end up with `checkValidInputRange` having a O(n²) complexity. Which means ~10k operations if the array has a size close to 100.

.map((_, i) => 1 / (i + 1))
.reverse(),
outputRange: Array(144)

- [Android] We introduce AnimatedNodeWithUpdateableConfig interface with a method updateConfig. On ColorAnimatedNode.java, we use updateConfig to resolve and apply the color

Pull Request resolved: https://github.com/facebook/react-native/pull/32736
The ability to pass an additional property bag to further configure NativeAnimated is useful for a few reasons, e.g., experimentation with multiple implementations of the NativeAnimated module.
The specific use case this solves is on react-native-windows, where there are two underlying animation graph options, one "optimized" animation graph that uses UI.Composition, and another similar to the approach to iOS and Android that uses a frame rendering callback.
The platform configuration can be supplied to the animation node when `useNativeDriver` is set to `true`, and we pass the platform configuration object to the connected AnimatedValue and all it's children.

This change checks if the `AnimatedValue` is a native node and passes the callback to the `NativeAnimatedAPI.getValue` callback, defaulting to the previous current JS node state if the node is not native.

Summary:
NativeAnimationModule on Android is using batches to combine related updates together. In Fabric, this process is controlled by JS, which schedules starts batching when Animated component props are about to be updated.
In rare cases when there's no prop update (like calls to `setValue` on `AnimatedValue`), changes weren't applied until the next batch was scheduled. This change ensures that such changes get applied directly.
This problem doesn't happen on iOS or non-Fabric surfaces, because they use per-frame scheduling instead.
