Country codes is an helper package that provides country details given a particular localization, such as dial codes, ISO 3166 codes (alpha-2, alpha-3) and country names.
Country Codes #
Country codes package provides an easy to way to access country codes based on a provided Locale
.
Usage #
There are two main ways to use this package.
1. Default by using device region #
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 TextFormField
s 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)
2. Use a custom Locale
#
This 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.
Formatters #
DialCodeFormatter
#
Currently there's only available TextInputFormatter
which allows you to dynamically set the dial code dynamically on a TextFormField
.
TextFormField(
keyboardType: TextInputType.phone,
inputFormatters: [DialCodeFormatter()],
);
