Default locale error instead of warning in React Native app

[naffiq]

Hello! I've looked through issues, looks like it wasn't reported yet.

I have option to switch between locales, that have not been added to IntlProvider yet.

Expected behavior

I want to get YellowBox message that react-intl is using defaultLocale as warning.

Current behavior

I get runtime error and my app crashes. I believe that this is because this warning is reported with console.error() instead of console.warn()

Step to reproduce for BUG REPORT

I added react-intl with yarn and switched to locale I didn't add in debug mode
react-native run-ios

export default class App extends Component {
  static defaultProps = {
    locale: 'ru' // comes from redux
  };

  render() {
    const {locale} = this.props;

    return (
      <IntlProvider
        textComponent={Text}
        locale={locale}
      >
        <View>
          <FormattedMessage id='Example' defaultMessage='Example'/>
          <AppRouter/>
        </View>
      </IntlProvider>
    );
  }
}
