Spread operator in StyleSheet causes linter to crash

When I define a StyleSheet with a spread operator, the linter crashes.

Version

"eslint-plugin-react-native": "^2.2.1",

StyleSheet

const styles = StyleSheet.create({
  ...SettingsStyles,
  image: {
    height: 90,
    width: 90,
    borderRadius: 45,
  },
  profile: {
    flex: 1,
  },
  avatar: {
    alignItems: 'center',
    justifyContent: 'center',
    paddingTop: 15,
    paddingBottom: 15,
  },
});

Error

Workaround

const combineStyles = {
  ...SettingsStyles,
  image: {
    height: 90,
    width: 90,
    borderRadius: 45,
  },
  profile: {
    flex: 1,
  },
  avatar: {
    alignItems: 'center',
    justifyContent: 'center',
    paddingTop: 15,
    paddingBottom: 15,
  },
}

const styles = StyleSheet.create(combineStyles);
