As workaround - you can ignore this warnings in app entry:

if (__DEV__) {
  // eslint-disable-next-line global-require
  require("react-native").YellowBox.ignoreWarnings([
    "Warning: Failed child context type: Invalid child context",
  ]);
}

See: https://facebook.github.io/react-native/docs/debugging.html#in-app-errors-and-warnings

you must edit in file /node_modules/react-ntive-image-galary/src/libralaries/ViewPager/index.js, edit function keyExtractor ( line 262 ) to
keyExtractor (item, index) { return index.toString() }
