### What is the current behaviour?

Reproducible repo at https://github.com/semireg/RNSemiBoilerplate/tree/fa3829669fda5cb5396eea26a6021513103f7357. This react native boilerplate uses RN 0.57.4, babel 7, flow, flow-runtime, immutable, redux, redux-immutable.

App build is broken due to TransformError when native app loads bundle.

iOS:
```
Failed to load bundle(http://localhost:8081/index.bundle?platform=ios&dev=true&minify=false) with
error:(node_modules/react-native/Libraries/Components/RefreshControl/RefreshControl.js: Property

### What is the expected behaviour?

Build should bundle and load without error.

I've tried clearing my caches/tmp directories, build assets, etc via:

```
watchman watch-del-all && rm -rf $TMPDIR/react-* && rm -rf $TMPDIR/metro* && rm -rf $TMPDIR/haste-*
rm -rf node_modules
yarn install
```

If the repo above does not reproduce the error, can anyone think of other directories that I need to reset that could be tainted?

I have searched GitHub issues, Google, and Stack Overflow and can not find any similar issues.
