[Helongzhou]

selectCountry(country) {
    this.setState({countryCode: country.cca2});
    this.setState({country});
  }

  render() {
    const {countryCode, country} = this.state;
    return (
      <View style={styles.container}>
        <CountryPicker
          countryCode={countryCode}
          withFilter
          withFlag
          withCountryNameButton
          withAlphaFilter
          onSelect={this.selectCountry.bind(this)}
          translation="eng">
          <View />
        </CountryPicker>
        <Text style={styles.instructions}>Press on the flag to open modal</Text>
        {country !== null && (
          <Text style={styles.data}>{JSON.stringify(country, null, 2)}</Text>
        )}
      </View>
    );
  }

withCountryNameButton not work because i used translation. if i remove ' translation="eng"',it work.

We don't have 'eng' translation. English is the 'common' translation.
