I'm temporarily working around this by adding these files to my [untyped] option in .flowconfig.

[untyped]
.*/node_modules/react-native/Libraries/Components/Navigation/NavigatorIOS.ios.js
.*/node_modules/react-native/Libraries/Components/TextInput/InputAccessoryView.js
.*/node_modules/react-native/Libraries/Components/View/ViewPropTypes.js

It looks like you are using an older version of React Native. Please update to the latest release, v0.57 and verify if the issue still exists.

The ":rewind:Old Version" label will be removed automatically once you edit your original post with the results of running react-native info on a project using the latest release.

I am closing this issue because it does not appear to have been verified on the latest release, and there has been no followup in a while.
