* **Who does this affect**: Users that are manually calling the methods on KeyboardingAvoidingView.
* **How to migrate**: Add an underscore before the name of the method
* **Why make this breaking change**: These methods are not meant to be public. For example, the exposed `onLayout` function is not a prop that accepts a function like is typical of the rest of React Native but is the internal method that is called when the component's onLayout is triggered.
* **Severity (number of people affected x effort)**: Low

Summary:
It's currently possible to crash React Native on iOS when using XMLHTTPRequest with onreadystatechange by having the server send a bunch of bad unicode (we found the problem when a bad deploy caused this to happen).
This is due to an integer overflow when handling carryover data in decodeTextData.
Create Express server with mock endpoint:
```js
var express = require('express');
var app = express();
app.get('/', function(req, res) {
res.writeHead(200, {'content-type': 'text/plain; charset=utf-8'});
res.flushHeaders();
res.write(new Buffer(Array(4097).join(0x48).concat(0xC2)));
res.write(new Buffer([0xA9]));
res.end();
});
app.listen(3000);
```
Create React Native application which tries to hit the endpoint:
```js
export default class App extends Component<{}> {
componentDidMount() {
const xhr = new XMLHttpRequest()
xhr.open('get', 'http://localhost:3000', true);
xhr.onreadystatechange = function () {
if(xhr.readyState === XMLHttpRequest.DONE && xhr.status === 200) {
console.warn(xhr.responseText);
}
};
xhr.send();
}
render() {
return null;
}
}
```
Observe that the application crashes when running master and doesn't when including the changes from this pull request.

Summary:
Allow end users to access the YellowBox API so that warnings can be properly ignored via the API first introduced in a974c140db. Based on that API, you should be able to do the following:
```
import { YellowBox } from 'react-native';
YellowBox.ignoreWarnings(['Warning: ...']);
```
However, if you actually try this today, it results in a broken import error.
Verified using an expo instance. First tried without the YellowBox import, observed a failure to import. Then I added the import statement, and observed no warning on my device.
```
import React from 'react';
import { StyleSheet, Text, View, YellowBox } from 'react-native';
YellowBox.ignoreWarnings(['hey']);
export default class App extends React.Component {
render() {
console.warn('hey!');
return (

While building a React Native application, I've come across the use case of wanting to set a specific locale for DatePickers irrespective of the users OS region setting. Since this is a feature available to native DatePicker components, I think it would be helpful to expose this in React Native as well.
Testing can be done by passing a `locale` prop to a DatePickerIOS. Example:
```
<DatePickerIOS
date={this.state.date}
mode="date"
locale="fr_FR"
onDateChange={date => this.setState({ date: date })}
/>
```

I want to animate `shadowOpacity` style property with Native Animated (`useNativeDriver: true`). This is useful for example in an ios-like navigation transition where the shadow fades in with the view that is sliding in from the side. Code comment for `STYLES_WHITELIST` says:
_In general native animated implementation should support any numeric property that doesn't need to be updated through the shadow view hierarchy (all non-layout properties)._
so I just added `shadowOpacity` (and `shadowRadius` too because why not?).
Before this change, setting `shadowOpacity` (or `shadowRadius`) to an `AnimatedValue` (with `useNativeDriver: true`) would throw the error: `Style property 'shadowOpacity' is not supported by the native animated module`.
After adding `shadowOpacity` (and `shadowRadius`), there is no error. The animation looks correct so it seems to be working. I also tried setting a ridiculously large `shadowRadius` and could see that working too.
Please advice on any further testing I should do.

It was just annoying me, and it has no side effects. If there are side effects, then we should fix the type and not go with empty to represent void.
Update project settings in Xcode. This code doesn't have any known side effects since the compiler assumes the type is void when not declared.

Summary:
This usage of `...` currently causes BackHandler to silently become non-functional when a `Symbol` polyfill is used.
Why?
- The `[...obj]` operator implicitly calls the object's iterator to fill the array
- react-native's internal `Set` polyfill has a load order issue that breaks it whenever a project uses a `Symbol` polyfill
- This means that when `BackHandler` tries to `[...set]` a `Set` of subscriptions the result is always an empty array instead of an array of subscriptions
Additionally it's worth noting that the current code is also wastefully inefficient as in order to reverse iterate over subscriptions it:
- Clones the `Set` (which fills it by implicitly running the set's iterator)
- Uses `[...set]` to convert the cloned set into an array (which also implicitly runs the iterator on the clone)
- Finally reverses the order of the array
----
This code fixes this problem by replacing the use of multiple Set instance iterators with a simple `.forEach` loop that unshifts directly into the final array.
I've tested this by opening the repo's RNTester app on Android and tvOS ensuring that the back handler works before changes, the application crashes when I introduce an error (to verify my code changes are being applied to the app), the back handler works and after changes.

Summary:
The relevant changes in the PR are to Libraries/StyleSheet/EdgeInsetsPropType.js; the rest are just removals of FlowIgnores.
The definition of the relevant types is [here](https://github.com/facebook/flow/blob/master/lib/react.js#L262-L271).
The long and short of it is that for whatever reason, Flow is unable to realize that `ReactPropsChainableTypeChecker` is a subtype of `ReactPropsCheckType` unless we assert it. Once we explicitly hint this to the typechecker, it realizes that `EdgeInsetsPropType` is indeed a valid React PropType, and stops complaining that it isn't.

Summary:
Touch cancel events are currently being ignored by the ScrollView component. Currently scrollview responds both to scroll events and touchStart/touchMove/touchEnd events.
The reason why ScrollView listens to touchStart/touchEnd is so that it can update its `state.isTouching` param. This parameter then is used in `scrollResponderHandleScrollShouldSetResponder` to make the decision if scrollview should set the responder or not. So if `isTouching` is true (we've received touchStart) then ScrollView want to became a JS responder. This in turn is important for the case where we receive scroll events that does not necessarily need to trigger responder change, e.g. we don't want Scrollview to become JS responder if scroll events have been triggered by `scrollTo` in which case setting responder would put the whole responder system in a bogus state (note that responder can be released only by touchEnd or touchCancel, so if there is no touchEnd that follows scroll event then ScrollView will remain the responder and this would break next touch interaction).
It is therefore crucial for the ScrollView to reset `isTouching` state when touchCancel arrives, as otherwise the next scroll event would incorrectly trigger responder change.
On top of that ScrollView seems to be the only component in RN's core that registers to handle touchEnd but ignores touchCancel, which stands agains the comment added to `RCTRootView.cancelTouches` [here](https://github.com/facebook/react-native/commit/c14cc123d#diff-9cd70243bd2af75c613e29972bb1b41cR127).
This problem is difficult to test with a pure RN native app, as on Android it does not surface because of the `responderIgnoreScroll` flag that is being added to every scroll event, and it essentially makes the responder system ignore scroll events so they would never trigger responder change. On the other hand on iOS the cancel events are pretty rare. With pure RN app they can only be triggered by a "system" level interaction (e.g. when system alert dialog appears or when home button is clicked and there is a touch interaction happening). This issue becomes more prominent when RN app is embedded in a more sophisticated application that may use [`RCTRootView.cancelTouches`](1e8f3b1102/React/Base/RCTRootView.h (L130)) method to block RNs gesture recognizers in some cases or with third-party libraries that deals with touch events like [react-native-gesture-handler](https://github.com/kmagiera/react-native-gesture-handler) that also calls into the method when native touch interaction is detected.
