Summary:
Nice addition of the recent Flow types for style props in 9c29ee1504, however I think there are some slight issues in the definition.
`type Styles = {[key: string]: Object}` makes sense, as it's referring to the set of named style groups a user creates a `StyleSheet` from, e.g.
```javascript
const styles: StyleSheet = StyleSheet.create({
container: {
height: 20
},
text: {
color: '#999',
fontSize: 12,
},
}: Styles)
```
However `type StyleValue = {[key: string]: Object}` doesn't make sense. You actually want only the `Object` portion of that definition, presuming it's meant to be used like below:
```javascript
type MyTextProps = {
style: StyleProp,
}
<MyText style={{ color: '#999', fontSize: 12 }}>Hello</Text>
```
---
I've also added `void` to the `StyleValue`, as undefined seems to be handled fine, and can be a useful shorthand in JSX.
---
And finally, I've allowed nesting of style prop arrays, by making StyleProp self-referencing, as RN seems to flatten those without issue. This can be important if you're passing in a style prop quite high up the component tree, and sticking it in an array with other styles at several points while it's passed down.

[INTERNAL] [MINOR] [StyleSheet] - Refine Flow types

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:
The overflow: visible option does not work on Android. This just add a little note to the docs of that property to make that clear.
See #3198 and https://react-native.canny.io/feature-requests/p/add-overflow-support-to-android .
Make it clear that this property is unavailable on Android. We had to figure this out by trial and error when porting an existing codebase, a small note in the docs would be helpful!
I could not find how to build the website - I tried `cd website && npm install && node ./server/generate.js` but I'm getting an error (*JSDOC_ERROR: There are no input files to process.*). But it is such a small change I can't see how it would break the docs build!

Summary:
This diff adds display:none support to React Native. This enables hiding components which still calling their render method and keeping them within the state of your application. This enables preserving state in a component even though the component is not visible. Previously this was often implemented by rendering a component off screen as a work around. See below playground for usage.
```
class Playground extends React.Component {
render() {
return (
<View style={{width: '100%', height: '100%', flexDirection: 'row', backgroundColor: 'white'}}>
<View style={{width: 100, height: 100, display: 'none', backgroundColor: 'red'}}/>
<View style={{width: 100, height: 100, backgroundColor: 'blue'}}/>
</View>
);
}
}

Summary:
This improves JS validations of the transform object and makes it a bit stricter (hence the breaking change). When moving transform objects parsing to native (#10658) the validations got out of sync a bit, this makes sure JS validations are the same or stricter than the native ones to make sure we get consistent errors across platforms.
See #12110 for an example of an error that now gets caught by JS validations.
Also added snapshot tests for the errors to make sure `processTransform` throws when passing invalid values. It only tests the validation since the object parsing is now done natively for iOS and Android.
**Test plan**
Test that there are no errors in UIExplorer

Summary:
In theory, we should be able to animate any non-layout property, including custom ones. While there is still work to be done on the native side to fully enable this, we should start by dropping the prop whitelist.

Summary:
**Motivation**
On Exponent we load fonts dynamically and assign their native names by appending a session id, so that fonts from one Exponent "experience" do not clash with each other. So, before sending the `fontFamily` to native, we want to change it to the Exponent-scoped `fontFamily`.
Example:
```js
// Before rendering your app
StyleSheet.setStyleAttributePreprocessor('fontFamily', _processFontFamily);
function _processFontFamily(name) {
// Pass system fonts through
if (!name || Constants.systemFonts.indexOf(name) >= 0) {
return name;
}
if (!Font.isLoaded(name)) {
if (__DEV__) {
console.error(`${name} is not a system font and has not been loaded through Exponent.Font.loadAsync. If you intended to use a system font, make sure you typed the name correctly and that it is supported by the current operating system. If this is a custom font, be sure to load it with Exponent.Font.loadAsync`);
} else {
return 'system';
}
}
return `ExponentFont-

Summary:
This fixes measuring of items in the main axis of a container. Previously items were in a lot of cases measured with UNSPECIFIED instead of AT_MOST. This was to support scrolling containers. The correct way to handle scrolling containers is to instead provide them with their own overflow value to activate this behavior. This is also similar to how the web works.
This is a breaking change. Most of your layouts will continue to function as before however some of them might not. Typically this is due to having a `flex: 1` style where it is currently a no-op due to being measured with an undefined size but after this change it may collapse your component to take zero size due to the implicit `flexBasis: 0` now being correctly treated. Removing the bad `flex: 1` style or changing it to `flexGrow: 1` should solve most if not all layout issues your see after this diff.

Summary: Introduce `overflow:scroll` so that scrolling can be implemented without the current overflow:visible hackiness. Currently we use AT_MOST to measure in the cross axis but not in the main axis. This was done to enable scrolling containers where children are not constraint in the main axis by their parent. This caused problems for non-scrolling containers though as it meant that their children cannot be measured correctly in the main axis. Introducing `overflow:scroll` fixes this.
