Flutter Intl (0.18!): Changing language for weekday

I want to change the language for the weekdays in intl: enter image description here

to German. In my code, I do this:

final weekdayFormatter = DateFormat('E');
final date = mostRecentWeekday(_currentDate, 1).add(Duration(days: i)); "<-- Function to get current monday"
...
 Text(weekdayFormatter.format(date)),

So I want Mo Di Mi Do which stands for Montag Dienstag Mittwoch […]

I tried this function: initializeDateFormatting();
but I don’t understand what parameters this function needs, especially the path parameter… all posts I were able to found are outdated

    I solved it by do:

      final weekdayFormatter = DateFormat.E('de_DE');

    instead of:

    final weekdayFormatter = DateFormat('E');

    also:

          localizationsDelegates: const [
        GlobalMaterialLocalizations.delegate,
        GlobalCupertinoLocalizations.delegate,
        DefaultWidgetsLocalizations.delegate,
        GlobalWidgetsLocalizations.delegate,
      ],

    inside Matrerial app and

    dependencies:
  flutter:
    sdk: flutter
  flutter_localizations:
    sdk: flutter

    inside pub file

    and using intl 17.

    Hello you can try it initializeDateFormatting('de_DE', null);

    Add a line of code to the initState() method

    First in your route MaterialApp Widget add this parameter :

          localizationsDelegates: [
        GlobalMaterialLocalizations.delegate,
        GlobalCupertinoLocalizations.delegate,
        DefaultWidgetsLocalizations.delegate,
        GlobalWidgetsLocalizations.delegate,
      ],

    then use this script as language changer anywhere you need:

        initializeDateFormatting('de_DE');
    final weekdayFormatter = DateFormat('E', 'de_DE');
    final date = DateTime.now();
    print(weekdayFormatter.format(date)); // it will print Do

    Make sure you use the right import of initializeDateFormatting. The easiest is to use import 'package:intl/date_symbol_data_local.dart', for web and for custom file loading other variants exist in date_symbol_data_http_request.dart and date_symbol_data_file.dart.
