Country codes package provides an easy to way to access country codes based on a provided Locale.
There are two main ways to use this package.
This will allow you to fetch the region of the underlying platform and display the data accordingly. Very handy if you use along with the DialCodeFormatter to provide integration with dial codes formatter, on phone TextFormFields in a Form, for example.
Assuming an en-US region based revice.
await CountryCodes.init(); // Optionally, you may provide a `Locale` to get countrie's localizadName
final Locale deviceLocale = CountryCodes.getDeviceLocale();
print(deviceLocale.languageCode); // Displays en
print(deviceLocale.countryCode); // Displays US
final CountryDetails details = CountryCodes.detailsForLocale();
print(details.alpha2Code); // Displays alpha2Code, for example US.
print(details.dialCode); // Displays the dial code, for example +1.
print(details.name); // Displays the extended name, for example United States.
print(details.localizedName); // Displays the extended name based on device's language (or other, if provided on init)
LocaleThis will use the provided Locale, which may not be related to the device's region but instead to the app supported languages.
For example, if your device is on US region but the app only supports PT, you'll get the following:
final CountryDetails details = CountryCodes.detailsForLocale(Localization.localeOf(context));
print(details.alpha2Code); // Displays alpha2Code, displays PT.
print(details.dialCode); // Displays the dial code for PT, +351.
print(details.name); // Displays the extended name, Portugal.
DialCodeFormatterCurrently there's only available TextInputFormatter which allows you to dynamically set the dial code dynamically on a TextFormField.
TextFormField(
keyboardType: TextInputType.phone,
inputFormatters: [DialCodeFormatter()],
);
