getDescriptionForNumber method
As per getDescriptionForValidNumber(PhoneNumber, Locale, String) but explicitly checks the validity of the number passed in.
number
the phone number for which we want to get a text description
languageCode
the language code for which the description should be written
userRegion
the region code for a given user. This region will be omitted from the
description if the phone number comes from this region. It should be a two-letter
upper-case CLDR region code.
returns a text description for the given language code for the given phone number, or empty
string if the number passed in is invalid or could belong to multiple countries
Implementation
String getDescriptionForNumber(PhoneNumber number, Locale languageCode,
[String? userRegion]) {
if (userRegion == null) {
PhoneNumberType numberType = _phoneUtil.getNumberType(number);
if (numberType == PhoneNumberType.unknown) {
return "";
} else if (!_phoneUtil.isNumberGeographical(
phoneNumberType: numberType,
countryCallingCode: number.countryCode)) {
return _getCountryNameForNumber(number, languageCode);
}
return getDescriptionForValidNumber(number, languageCode);
} else {
PhoneNumberType numberType = _phoneUtil.getNumberType(number);
if (numberType == PhoneNumberType.unknown) {
return "";
} else if (!_phoneUtil.isNumberGeographical(
phoneNumberType: numberType,
countryCallingCode: number.countryCode)) {
return _getCountryNameForNumber(number, languageCode);
}
return getDescriptionForValidNumber(number, languageCode, userRegion);
}
