Summary:First I searched for special cases that destructor PropTypes:
```
(?s)React\s*=\s*require\('react\-native'\).*(Children|PropTypes)[^\{\}]*\}\s*=\s*React;
```
I split them up manually.
Then I replaced the React = require('react-native') + destructuring pattern...
```
(?s)(const|var)\s+React\s*=\s*require\('react\-native'\)(.*[^\{\}]*\}\s*=\s*)React;
```
...with...
```
$1 React = require('react');
$1 ReactNative = require('react-native')$2ReactNative;
```
I used lint to figure out if I left some unnecessary imports.
Finally I grepped for just
```
React\s*=\s*require\('react\-native'\)
```
to catch any remaining patterns.
Also, `} = React.NativeModules` -> `} = ReactNative.NativeModules`.
