There are some errors I noticed after upgrading my flow version.  I had them in my project, and they were also reported in #11655.  These errors were ignored on master, but I went through and fixed them so the static analysis will work still.

After these changes, I receive no errors using flow `0.60.1` on latest master, or using `0.59` in my local project (which does not have the requisite ignores included).

- init a new project
     `react-native init --version <path-to-repo> helloworld`
- add the flow binary
     `yarn add -D flow-bin`
- run flow
     `yarn flow`
- make sure there are no errors in the project.
     ```
     No errors!
       Done in 23.60s.

James Isaac 820cfa1f3b Refine StyleSheet Flow types
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.

N/A (These types aren't referenced anywhere else)

ashoat 833b27483b Fix Flow errors at declaration of most major library components
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.

Joe Rickerby fa147f02e5 Update overflow docstring to add note on Android
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'}}/>

Janic Duplessis 0ed31eb3d6 BREAKING - Improve JS transform validation, add tests
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
Run new unit tests

Ryan Gomba 7e869b9d0a Drive any numerical prop via NativeAnimated
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.

Brent Vatne 346858a552 Add StyleSheet.setStyleAttributePreprocessor
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';
    }
  }
