Added language to explain that you still need to add keys for each section even if you use a keyExtractor method.
No code changed; just clarified documentation.

Summary:
This fixes support for the `backgroundColor` style prop on an `ART.Surface`.
`ARTSurfaceViewManager` inherits its `setBackgroundColor` implementation from `BaseViewManager`. This implementation broke in API 24 because API 24 removed support for `setBackgroundColor`on `TextureViews`. `ARTSurfaceView` inherits from `TextureView` so it also lost support for `setBackgroundColor`.
To fix this, the implementation of `ART.Surface's` `setBackgroundColor` was moved to the shadow node. The implementation now draws the background color on the canvas.
In a test app, verified that initializing and changing the background color on an `ART.Surface` works. Verified that the background renders as transparent when a background color isn't set. Also, this change is being used in my team's app.

Summary: Move the returned type of `getPolyfills` from a standard `Array` to a read-only one, so that we make sure the array is not modified once created. Also, refactor the list of polyfills included by default to a generic, central file, then require it both from the CLI utils as well as the development server.

Summary:
The invariant condition doesn't allow scrolling to the last index
Here is a simple reproduction of the problem: https://snack.expo.io/BJ59gzWrZ
Surely, if the last item is rendered, we should be able to scroll to it without an invariant failing?
Tested locally that this change fixes the issue.

Summary:
This PR fixes#14975.
* Podspec: add InspectorInterfaces.h/cpp to the "jschelpers_legacy" subspec.
1. lint the Podspecs: `./scripts/process-podspecs.sh`
2. check that an iOS project can integrate "DevSupport" via Cocoapods again. I'll already checked it on this branch of the demo project: https://github.com/HeEAaD/Demo-ReactNative-0.47.0-rc2-Podspec-issue/tree/fix

Summary:
It is quite confusing that the 'data:' uri scheme is not documented, but working.
It is very useful when getting e.g. an icon from a REST call.
Also, the mandatory size style for network & data images should be mentioned here, not only in the image guide.

Summary:
It's very important in complex UIs to be able to apply alpha channel-based masks to arbitrary content. Common use cases include adding gradient masks at the top or bottom of scroll views, creating masked text effects, feathering images, and generally just masking views while still allowing transparency of those views.
The original motivation for creating this component stemmed from work on `react-navigation`. As I tried to mimic behavior in the native iOS header, I needed to be able to achieve the effect pictured here (this is a screenshot from a native iOS application):

In this image, there are two masks:
- A mask on the back button chevron
- A gradient mask on the right button
In addition, the underlying view in the navigation bar is intended to be a UIBlurView. Thus, alpha masking is the only way to achieve this effect.
Behind the scenes, the `maskView` property on `UIView` is used. This is a shortcut to setting the mask on the CALayer directly.
This gives us the ability to mask any view with any other view. While building this component (and testing in the context of an Expo app), I was able to use a `GLView` (a view that renders an OpenGL context) to mask a `Video` component!
I chose to implement this only on iOS right now, as the Android implementation is a) significantly more complicated and b) will most likely not be as performant (especially when trying to mask more complex views).
Review the `<MaskedViewIOS>` section in the RNTester app, observe that views are masked appropriately.

_What existing problem does the pull request solve?_
On Linux, the packager caught an "Google Chrome exited with error: { Error: spawn google-chrome ENOENT}" when trying to launch the devTools because google-chrome is not installed but chromium is.
Thus, this pull request maps the platform Linux with chromium for launching the debugger automatically in the packager
_A good test plan has the exact commands you ran and their output, provides screenshots or videos if the pull request changes UI or updates the website._
- enter on terminal
> react-native start
- launch the app in dev mode with "Debug JS remotely" enabled
- the packager prints "Launching Dev Tools..." and launch chromium with the debugger
