Environment

OS: Linux 4.13 Node: 9.10.1 Yarn: 1.6.0 npm: 5.6.0 Watchman: Not Found Xcode: N/A Android Studio: Not Found

Packages: (wanted => installed) react: 16.3.1 => 16.3.1 react-native: 0.55.3 => 0.55.3

Solved changing to keyExtractor={(item, index) => index.toString()} in _nodemodules/react-native-image-gallery/src/libraries/ViewPager/index.js

Is this the real issue here? If this a problem with the module then shouldn't that be fixed via a PR?

[robreuss]
