Flutter Local routes issue - flutter

Question

I have a small problem with a flutter local app. I am trying to have 2 routes depending on device languageCode. When I build the app, that second option are launched. If I save the app, the right route are picked. I think the
final lang = locale.languageCode;
Do not have a value when this is called:
"/newsfeed": lang == "da"
? (BuildContext context) => News()
: (BuildContext context) => NewsEN(),
The print statement I have in the code have the right value, so are a bit lost Here are the code:
class MyApp3 extends StatelessWidget {
#override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
primarySwatch: Colors.blue,
),
// List all of the app's supported locales here
supportedLocales: [
Locale('en', 'US'),
Locale('da', 'DK'),
],
// These delegates make sure that the localization data for the proper language is loaded
localizationsDelegates: [
// A class which loads the translations from JSON files
AppLocalizations.delegate,
// Built-in localization of basic text for Material widgets
GlobalMaterialLocalizations.delegate,
// Built-in localization for text direction LTR/RTL
GlobalWidgetsLocalizations.delegate,
],
// Returns a locale which will be used by the app
localeResolutionCallback: (locale, supportedLocales) {
// Check if the current device locale is supported
for (var supportedLocale in supportedLocales) {
//print(locale.languageCode);
final lang = locale.languageCode;
print(lang);
if (supportedLocale.languageCode == locale.languageCode &&
supportedLocale.countryCode == locale.countryCode) {
return supportedLocale;
}
}
// If the locale of the device is not supported, use the first one
// from the list (English, in this case).
return supportedLocales.first;
},
home: MyHomePage(),
routes: <String, WidgetBuilder> {
//"/Knowledge_pick": (BuildContext context) => SplashScreen(),
"/calculator_pick": (BuildContext context) => Pickcalculator(),
//"/receipe_pick": (BuildContext context) => Receipemenu(),
"/receipe_pick": (BuildContext context) => Wrapper(),
"/newsfeed": lang == "da"
? (BuildContext context) => News()
: (BuildContext context) => NewsEN(),
Hope someone can help me with this problem.

Honestly I don't see why this wouldn't work but what you should try to do is setup two different routes, one from 'da' and one for 'en'
"/newsfeedDA": (BuildContext context) => News(),
"/newsfeedEN": (BuildContext context) => NewsEN(),
and have your logic for selecting them in the initState or constructor of MyHomePage().
