获取本地化的星期几

Question

我想向用户显示一周中某天的本地化列表（用于设置重复事件）。我可以看到MaterialLocalizations类具有一个narrowWeekdays列表，您可以将其与firstDayOfWeekIndex属性一起使用，但是narrowWeekdays只是1或2个字母（取决于语言环境） ）。

令人讨厌的是，该实现似乎有一个_weekdays列表，但仅用于格式化长日期，并且不像窄名那样公开：（

有什么想法吗？

我已经“黑客入侵”了以下内容，但似乎应该容易得多：

  List<String> _getLocalizedDayNames(BuildContext context) {
    var localizations = MaterialLocalizations.of(context);

    // 6th August 2018 is a Monday.
    final DateFormat longDayName = DateFormat.EEEE();
    final oneDay = Duration(days: 1);
    final DateTime monday = DateTime.utc(2018, DateTime.august, 6);
    final DateTime tuesday = monday.add(oneDay);
    final DateTime wednesday = tuesday.add(oneDay);
    final DateTime thursday = wednesday.add(oneDay);
    final DateTime friday = thursday.add(oneDay);
    final DateTime saturday = friday.add(oneDay);
    final DateTime sunday = saturday.add(oneDay);
    final weekdays = <String>[
      longDayName.format(monday),
      longDayName.format(tuesday),
      longDayName.format(wednesday),
      longDayName.format(thursday),
      longDayName.format(friday),
      longDayName.format(saturday),
    ];
    if (localizations.firstDayOfWeekIndex == 0) {
      // Sunday is the first day of the week.
      weekdays.insert(0, longDayName.format(sunday));
    } else {
      weekdays.add(longDayName.format(sunday));
    }

    return weekdays;
  }
