每周本地通知方法

Question

我正在使用本地Flutter通知插件，

我需要在特定时间（例如，凌晨4:00）进行每周通知。

var time = new Time(10, 0, 0);
var androidPlatformChannelSpecifics =
    new AndroidNotificationDetails('show weekly channel id',
        'show weekly channel name', 'show weekly description');
var iOSPlatformChannelSpecifics =
    new IOSNotificationDetails();
var platformChannelSpecifics = new NotificationDetails(
    androidPlatformChannelSpecifics, iOSPlatformChannelSpecifics);
await flutterLocalNotificationsPlugin.showWeeklyAtDayAndTime(
    0,
    'show weekly title',
    'Weekly notification shown on Monday at approximately ${_toTwoDigitString(time.hour)}:${_toTwoDigitString(time.minute)}:${_toTwoDigitString(time.second)}',
    Day.Monday,
    time,
    platformChannelSpecifics);

这是来自本地通知插件文档，但我无法满足我的要求
