Using the intl package, the easiest way I found would be:

import 'package:intl/intl.dart';

var days = DateFormat.EEEE(Platform.localeName).dateSymbols.STANDALONEWEEKDAYS;

print(days)  // => ["Sunday", "Monday", ..., "Saturday"]

You can replace STANDALONEWEEKDAYS with WEEKDAYS to get the names as they would appear within a sentence (e.g. first letter lowercase in some languages).

Also, you may use SHORTWEEKDAYS and STANDALONESHORTWEEKDAYS respectively to get the weekday abbreviations. For even shorter abbreviations, use NARROWWEEKDAYS or STANDALONENARROWWEEKDAYS.

In case you need the current day or month localized with your phone settings

import 'dart:io';
import 'package:intl/date_symbol_data_local.dart';

final String defaultLocale = Platform.localeName; // Phone local
// String defaultLocale = "pt_BR"; // "en_US" etc. you can define yours as well

// add to init 
@override
void initState() {
  super.initState();
  initializeDateFormatting(defaultLocale);
} 

static String _getLocalizedWeekDay(String local, DateTime date) {
    final formatter = DateFormat(DateFormat.WEEKDAY, local);
    return formatter.format(date);
}

static String _getLocalizedMonth(String local, DateTime date) {
    final formatter = DateFormat(DateFormat.MONTH, local);
    return formatter.format(date);
}

My suggestion is:

static List<String> getDaysOfWeek([String locale]) {
  final now = DateTime.now();
  final firstDayOfWeek = now.subtract(Duration(days: now.weekday - 1));
  return List.generate(7, (index) => index)
      .map((value) => DateFormat(DateFormat.WEEKDAY, locale)
          .format(firstDayOfWeek.add(Duration(days: value))))
      .toList();
}

The idea is we define the date of the first day in the current week depending on current week day. Then just do loop 7 times starting from calculated date, add 1 day on each iteration and collect the result of DateFormat().format method with pattern DateFormat.WEEKDAY. To increase performance you can use lazy initialization. For example:

/// Returns a list of week days
static List<String> _daysOfWeek;
static List<String> get daysOfWeek {
  if (_daysOfWeek == null) {
    _daysOfWeek = getDaysOfWeek(); // Here you can specify your locale
  }
  return _daysOfWeek;
}

After doing:

import 'package:intl/date_symbol_data_local.dart';

String localeName = "pt_BR"; // "en_US" etc.
initializeDateFormatting(localeName);

Use this:

static List<String> weekDays(String localeName) {    
    DateFormat formatter = DateFormat(DateFormat.WEEKDAY, localeName);
    return [DateTime(2000, 1, 3, 1), DateTime(2000, 1, 4, 1), DateTime(2000, 1, 5, 1),
      DateTime(2000, 1, 6, 1), DateTime(2000, 1, 7, 1), DateTime(2000, 1, 8, 1),
      DateTime(2000, 1, 9, 1)].map((day) => formatter.format(day)).toList();
}

I'm not sure it qualifies as "easy". Maybe someone here can come up with a better answer.
