Summary:Currently, we're not taking advantage of Flow's built-in type definitions for the React library in all cases because Flow's definition uses `declare module react` and this file uses `import('React')`, which Flow thinks is a different library. After this change, the following starts working which didn't before:
```js
import { Component } from 'react-native';
class MyText extends Component<void, {text: string}, void> {
render() { return <Text>{this.props.text}</Text> }
}
// Correctly throws a Flow error for the missing "text" prop
const renderedText = <MyText />;
```

This fixes a bug in UIExplorer, where platform labels on examples like (ios only) or (android only) would be re-appended to the title each time the example was viewed.

Summary:
Update to https://github.com/facebook/react-native/pull/1969
--
Recent improvements allow RCTImageLoader to select a more appropriate sized image based on the layout dimensions. Sizes:
- asset.thumbnail
- asset.aspectRatioThumbnail
- asset.defaultRepresentation.fullScreenImage
- asset.defaultRepresentation.fullResolutionImage
Prior, only the fullResolutionImage was used. This was memory intensive and resulted in crashes when loading several large images at once. The updated implementation works well, but can be made more efficient:
Consider loading 10 8MP (3264x2448) images in 150x150 pixel containers. The target size (150x150) is larger than asset.thumbnail (approx 100x100), therefore the fullScreenImage representation is used instead (approx 1334x1000).
This commit will scale the asset to the minimum size required while taking into account original aspect ratio and device scale. Memory usage is considerably lower and many more images can be loaded in
sequence without having to worry
