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 />;
```
