replaceSubdomainWithCodes static method

Uri replaceSubdomainWithCodes(Uri uri, { String? languageCode, String? countryCode, })

Replaces the subdomain of an URI with specific country and language.

No default language nor country: null means no parameter. For instance

• https://world.xxx... would be standard
• https://world-fr.xxx... would be "no country" in French
• https://fr.xxx... would be France
• https://fr-es.xxx... would be France in Spanish

Implementation

static Uri replaceSubdomainWithCodes(
  final Uri uri, {
  final String? languageCode,
  String? countryCode,
}) {
  final String initialSubdomain = uri.host.split('.')[0];
  countryCode = countryCode ?? initialSubdomain;
  final String subdomain;
  if (languageCode != null) {
    subdomain = '$countryCode-$languageCode';
  } else {
    subdomain = countryCode;
  }
  return uri.replace(
    host: uri.host.replaceFirst('$initialSubdomain.', '$subdomain.'),
  );
}
