Easy Usage Validator #
Display your error message using the validator function. This is very simple to do
InternationalPhoneNumberInput(
validator: (number) {
if (number.number.isEmpty) {
return "The phone number cannot be left emptyssss";
}
return null;
},
)

Error Configuration #
PhoneConfig(
errorColor: const Color(0xFFFF5494),
popUpErrorText: true,
autovalidateMode: AutovalidateMode.onUserInteraction,
errorTextMaxLength: 2,
errorPadding: const EdgeInsets.only(top: 14),
errorStyle: const TextStyle(
color: Color(0xFFFF5494), fontSize: 12, height: 1)
)

What is popUpErrorText for? #
If you set popUpErrorText to 'true', no field is allocated for the error message. Therefore the height of InternationalPhoneNumberInput will be increased when the error appears. But if you set popUpErrorText to 'false', the space for the error message is allocated automatically. Therefore, the error message will not cause a height difference in your design

popUpErrorText=true

popUpErrorText=false

IntPhoneNumber #
Function "onInputChanged" will return an object with IntPhoneNumber type to you.
IntPhoneNumber:
print(phone.code); //US
print(phone.dial_code); //+1
print(phone.number); //553 142 88 74
print(phone.rawFullNumber); //15531428874
print(phone.rawNumber); //5531428874
print(phone.rawDialCode); //1

Load JSON data #
You can fetch the country codes from your own json file and upload them to the package.
For that, you must fill your json file with a certain format. Example on this:
[
{
"name": "Aland Islands",
"dial_code": "+358",
"code": "AX"
},
{
"name": "Albania",
"dial_code": "+355",
"code": "AL"
},
{
"name": "Algeria",
"dial_code": "+213",
"code": "DZ"
}
]

InternationalPhoneNumberInput(loadFromJson: loadFromJson)

return await rootBundle.loadString('assets/countries/country_list.json');
