Get Country

To programmatically retrieve country information, you can utilize the following helper function:

Get Country by ISO Code

To retrieve a country programmatically based on its ISO code, you can use the getCountryByIsoCode function. This function searches through a list of country objects and returns the one that matches the given ISO code. If no match is found, it returns null.

 Country? getCountryByIsoCode(String isoCode);

Fetch a Country by Its Country Code

For retrieving a country using its country code, the getCountryByCountryCode function is provided. Similar to getCountryByIsoCode, this function scans a list of country objects, finding and returning the one that matches the given country code. In cases where no country is found with the specified code, null is returned.

Country? getCountryByCountryCode(String countryCode)

Fetch a Country by Its Name

To find a country based on its name, you can use the getCountryByName function. This function searches through a list of country objects, returning the one whose countryName matches the provided name. If the search yields no results, the function returns null.

Country? getCountryByName(String countryName)

Usage Example:

final _pickCountryLookupService = PickCountryLookupService();

Country? c= _pickCountryLookupService.getCountryByIsoCode("uk");
