[prod build only] Object is null or undefined

[akiradeveloper]

This error arises once I changed from android:dev to android:prod. The RN version is 0.46.0 and library version is 0.5.1

My guess is that transpiler works badly; the calling of from method tells us that the pointed code isn't safe for the transpiler.

  static renderImageFlag(cca2, imageStyle) {
    return cca2 !== '' ? (
      <Image
        style={[styles.imgStyle, imageStyle]}
        source={{ uri: countries[cca2].flag }} // this is L112

[akiradeveloper]

Oh sorry, that was master branch's

the L112 (of v.0.5.1) is actually the line below (https://github.com/xcarpentier/react-native-country-picker-modal/blob/v0.5.1/src/CountryPicker.js)

  static renderFlag(cca2, itemStyle, emojiStyle, imageStyle) {
    return (
      <View style={[styles.itemCountryFlag, itemStyle]}>
        {isEmojiable
          ? CountryPicker.renderEmojiFlag(cca2, emojiStyle)
          : CountryPicker.renderImageFlag(cca2, imageStyle)}
      </View>
    )
  }

  constructor(props) {
    super(props)
    this.openModal = this.openModal.bind(this)

    let countryList = [...props.countryList] // L112
    const excludeCountries = [...props.excludeCountries]

[akiradeveloper]

I found that props.countryList is undefined

[akiradeveloper]

I think the cause is defaultProps is somewhat ignored

@akiradeveloper you right. I got this error too on my Android. And I was found and solve problem : <CountryPicker cca2={cca2.toUpperCase()} {...props} />

cca2 need to be in upper case. It help me
