This test is partially disabled already, causing high flakyness of the `test_windows` CI job.
I'm taking a different approach at disabling it here (disabling the offending tests using a `Promise`
rather than disabling at the assert level).

Summary:
State updates can be batched together idependent of `this.state`, so we should do any calculation deriving state from state within a `setState()` callback. This fixes a bug where we were relying on potentially stale state, a RenderMask derived from `this.state` instead of the `state` callback parameter, when triggering updates from focus.
Note that this is not exercised on Android/iOS, but it on desktop/web. I noticed this a while back while making another change, but that change got abandoned, so this is the independent fix.

Summary:
the current jsc-android is still built based on ndk r21, and react-native is now built based on ndk r23. the unwinder between r21 and r23 is incompatible (libgcc vs libunwind). if there's exceptions throwing from jsc, other react native libraries cannot catch these exceptions and cause runtime crash.
this pr updates jsc-android to 235231.0.0 which is the same webkitgtk version as 235230.2.1 but only built by ndk r23. the jsc-android pr is from https://github.com/react-native-community/jsc-android-buildscripts/pull/179. note that the jsc is based on ndk r23c and react-native is based on ndk r23b. the reason is that i cannot get jsc building successfully on r23b. hopefully r23b and r23c are abi safe.
there is another crash from libjscexecutor when testing the new jsc-android. to fix the issue, i have to explicitly link libunwind.a from libjscexecutor.so. supposedly ndk r23 should help to link libunwind under the hood, i still not figure out why it doesn't. but after linking libunwind.a, i can get new jsc-android work successfully.

Pull Request resolved: https://github.com/facebook/react-native/pull/36080
For Android release builds on Windows, gradle release build fails if there are spaces in path (https://github.com/facebook/react-native/issues/34878). This is due to gradle improperly handling arguments with spaces (this is also [an open issue](https://github.com/gradle/gradle/issues/6072) on Gradle). Since the Hermes compilation and other Gradle exec invocations involve arguments which will contain spaces (if there are spaces in your path), this also means it is hard to get around this by simply escaping the spaces (eg: by using double quotes), since these arguments are not properly handled by Gradle itself.
As a workaround, this PR uses relative paths for all Gradle commands invoked for Android. As long as there aren't any spaces in the react-native directory structure (i.e this repo), this fix should work.
## Changelog

Summary:
Both Android and iOS allow you to set application specific user interface style, which is useful for applications that support both light and dark mode.
With the newly added `Appearance.setColorScheme`, you can natively manage the application's user interface style rather than keeping that preference in JavaScript. The benefit is that native dialogs like alert, keyboard, action sheets and more will also be affected by this change.
Implemented using Android X [AppCompatDelegate.setDefaultNightMode](https://developer.android.com/reference/androidx/appcompat/app/AppCompatDelegate#setDefaultNightMode(int)) and iOS 13+ [overrideUserInterfaceStyle](https://developer.apple.com/documentation/uikit/uiview/3238086-overrideuserinterfacestyle?language=objc)
## Changelog
[GENERAL] [ADDED] - Added `setColorScheme` to `Appearance` module
Pull Request resolved: https://github.com/facebook/react-native/pull/35989
Test Plan:
This is a void function so testing is rather limited.
```tsx
// Lets assume a given device is set to **dark** mode.
Appearance.getColorScheme(); // `dark`
// Set the app's user interface to `light`
Appearance.setColorScheme('light');
Appearance.getColorScheme(); // `light`
// Set the app's user interface to `unspecified`
Appearance.setColorScheme(null);

Such combination was assumed not possible from the differ (https://fburl.com/code/kg8z9t4w), yet it happened at least in the existence of layout animation and when certain commits happen while animation is active.
This diff fixes all potential races in the Fabric mounting layer directly. It captures all the `DELETE...CREATE` combinations and stop those from passing down to the native platforms. This should fix all such races should them not captured by the fix in the layout animation.
To help understand other races better, I also logged here to indicate such race so that future crashes will have more context.

Summary:
Since currently the check was for null , and that too not === check. So added a check , only for item !== undefined, since null is an assigned value, and we can have null as values in the array for flatlist,
undefined is in absence of any data, hence if its only undefined we should assign falsy to frame variable, since null is an assigned value, sometimes null can be passed to data in the dataset
Hence added a check on top of Sam's previous commit to fix it
UPDATE:
Now after discussing with NickGerleman , removed the check for item with nullish/undefined.
Now directly frames value is being controlled by _keyExtractor function
This is already an issue [https://github.com/facebook/react-native/issues/35280](url)
Currently in my project, even [0,1] -> didnt trigger onViewableItemsChanged since, it was considered as falsy value,
went to check the node modules code for flatlist, debugged this.
When pulled latest main branch, saw it was partially fixed , but for null as values it wasnt fixed. So added that check .
## Changelog
[General] [Fixed] Fix VirtualizedList onViewableItemsChanged won't trigger if first item in data is null
```
const frame =
item !== undefined ? this._frames[this._keyExtractor(item, index, props)]

in place of existing which is
```
const frame =

Update:
`const frame = this._frames[this._keyExtractor(item, index, props)]`

This is a small refactor designed to make future merges for React Native macOS easier. It was found while merging React Native 0.71 into React Native macOS.
In React Native macOS, we ifdef iOS out API's and replace them with macOS APIs, reusing as much code as possible. `CGContext` is a type that is available on both iOS and macOS, but `UIGraphicsImageRendererContext` is not. A simple refactor makes it easier to reuse this code in React Native macOS without affecting iOS :)

> **Notice**: This commit does not change any behaviour.
Parse and collect enum members in module specs instead of the current behaviour of parsing enum members as 'string' / 'number' and ignoring the member names.
This commit would allow us to generate native Enums corresponding to the schema's enums.
Prior to this commit, enum params were parsed as:
```
{
'name': 'qualityParam',
'optional': false,
'typeAnnotation': {
'type': 'EnumDeclaration',
'memberType': 'StringTypeAnnotation'
}
},
```
The name of the enum type and the members of the enum type were ignored.
After this commit, parsed modules would hold a new object member called `enumMap` that would look like this:
```
'enumMap': {
'QualityEnum': {
'name': 'QualityEnum',
'type': 'EnumDeclarationWithMembers',
'memberType': 'StringTypeAnnotation',
'members': [
{
'name': 'SD',
'value': 'sd'
},
{
'name': 'HD',
'value': 'hd'
}
]
},
// ...
}
```
And enum params would be exported as:
```
{
'name': 'qualityParam',
'optional': false,
'typeAnnotation': {
'name': 'NativeModuleEnumTypeAnnotation',
'type': 'EnumDeclaration',
'memberType': 'StringTypeAnnotation'
}
},
```
Combining the two new outputs would allow us to generate Native enums in the Native generators.

Summary:
This is a prototype to add circular dependencies detection on CMake for ReactCommon and ReactAndroid.
It can be enabled per module and works as follows:
```
set(ALLOWED_HEADER_IMPORT_PATHS
react/renderer/graphics
react/debug)
check_for_circular_dependencies("${ALLOWED_HEADER_IMPORT_PATHS}")
```
The allowed header import path must be manually specified as libraries are exposing wrong header search paths (so can't be reused).
The CI will be red till the circular dependency on `graphics` is resolved.

I've also removed the explicit version in the template as now the AGP version

This also bumps the default CMake version in user space to 3.22 which resolves a lot

Summary:
Changelog: [Internal] Support hovering in/out of root views
Prior to this change, we did not have signal when an input device moved out of the root view and so our internal state would not be aware and we would not trigger enter/leave events.
This diff starts listening to `HOVER_EXIT` events as dispatched from `onInterceptHoverEvent` and assumes that's the right event to signal a cursor has moved out of the root view. We dispatch the relevant leave events for this case and update our internal state to ensure the next `HOVER_MOVE` in our rootview, will properly dispatch the enter events.
## Investigation for creating this diff
Determining the signal for when an inputDevice enters/exits our rootview wasn't straight-forward.
From my understanding Android event dispatching follows a similar capture, bubbling phase as web. With `onIntercept..` handlers to swallow events. See this explanation: https://suragch.medium.com/how-touch-events-are-delivered-in-android-eee3b607b038 and this video talk: https://youtu.be/EZAoJU-nUyI?t=929
However when trying to understand hover enter/exit events on the root view, my understanding of this logic broke down.
Here's what confused me:
* When moving a cursor from inside to outside the root view, I would receive `HOVER_ENTER/EXIT` MotionEvents on `onInterceptHoverEvent` and since we did not swallow them, we'd receive those same events on the bubble up in `onHover`. That makes sense.
* However, when I hovered from the rootview into a child view, I would receive MotionEvents of `HOVER_ENTER/HOVER_EXIT` in the `onHoverEvent` handler of the rootview without having seen them in the `onInterceptHoverEvent` (re: capture phase down). This was confusing, where was the capture down?
* What tips me off that these events (`HOVER_ENTER/EXIT`) don't follow the classic capture, bubbling model as explained in the linked article, is that I don't receive `HOVER_ENTER/HOVER_EXIT` events for each child view in the root view's `onInterceptHoverEvent`.
* Like when a cursor moves from root -> child, I'd expect to motion events 1. exit for the rootview, 2. enter for the child view. But I never receive the 2. from the root view --
* I also wonder if the wording for `HOVER_EXIT` events mean that these events are directly dispatched to the view? Re: ["This action is always delivered to the window or view that was previously under the pointer."](https://developer.android.com/reference/android/view/MotionEvent#ACTION_HOVER_ENTER)
* There also seems to be some optimizations around the dispatch path as mentioned in this video at this timestamp: https://youtu.be/EZAoJU-nUyI?t=929 for the UP gesture.. so maybe there's some optimization happening with hover events? I'm not sure how hover events are account for in gesture handling for Android.
