Flutter on iOS always chooses English for localization, even if the system's preferred language is not english #14128
Description
Steps to Reproduce
I have two languages set up on iOS and Android:
- German
- English
German is the preferred language of the system, meaning the OS and most apps appear in German.
I created an app that has translations for both English and German:
return new MaterialApp(
localizationsDelegates: <LocalizationsDelegate<dynamic>>[
new _MyLocalizationsDelegate(),
GlobalMaterialLocalizations.delegate,
GlobalWidgetsLocalizations.delegate,
],
supportedLocales: [
const Locale('de', 'DE'), // German
const Locale('en', 'US'), // English
],
title: "MyApp",
home: new Home(),
);class _MyLocalizationsDelegate extends LocalizationsDelegate<MyStrings> {
@override
Future<MyStrings> load(Locale locale) => MyStrings.load(locale);
@override
bool shouldReload(_MyLocalizationsDelegate old) => false;
@override
bool isSupported(Locale locale) =>
locale.languageCode == 'en' ||
locale.languageCode == 'de';
}On Android, this app appears in German. On iOS, it appears in English.
The only way to force the app to appear in German is to remove English as a secondary language of the system.
Is this a bug? Am I missing something?
