LocalNotificationsPlugin 应该每分钟使用不同的有效负载(变量“自定义”)调用。调用是循环进行的。我创建了插件类的一个新实例,然后使用设置对其进行初始化,以便为每个平台使用它。代码有效并显示推送通知。但是,仅显示最近的消息 -> 最后通过循环的消息。id 是根据随机数和时间唯一创建的。
为什么不能显示所有消息?非常感谢!
//Loop and create new Push Message
for (var i = 1; i <= final_list.length - 1; i++) {
//Info: Index not 0 because Index 0 value should not be used
final_message = final_list[i];
//Add payload
custom = final_message;
if (i == 1 ){
//First loop -> Selected time plus 1 min
finalmsgtime = selectedTime.add(new Duration(minutes: 1));
} else {
//Second loop and bigger -> finalmsgtime + 2 min //only for test :)
finalmsgtime = finalmsgtime.add(new Duration(minutes: 2));
}
//Date & Time
var now = new DateTime.now();
var notificationTime = new DateTime(
now.year, now.month, now.day, finalmsgtime.hour, finalmsgtime.minute);
//GET ID
var randomizer = new Random();
String id;
var num_id = randomizer.nextInt(10000);
id = '$num_id$now'; //Eindeutige ID
//Set push message
scheduleNotification(
flutterLocalNotificationsPlugin, id, custom, notificationTime);
} //Ende Loop
在此方法中,我们创建推送消息:
Future<void> scheduleNotification(
FlutterLocalNotificationsPlugin flutterLocalNotificationsPlugin,
String id,
String body,
DateTime scheduledNotificationDateTime) async {
var androidPlatformChannelSpecifics = AndroidNotificationDetails(
id,
'Reminder notifications',
'Remember about it',
icon: 'app_icon',
);
var iOSPlatformChannelSpecifics = IOSNotificationDetails();
var platformChannelSpecifics = NotificationDetails(
androidPlatformChannelSpecifics, iOSPlatformChannelSpecifics);
await flutterLocalNotificationsPlugin.schedule(0, 'Quote of the Day', body, //Titel von Push-Nachricht
scheduledNotificationDateTime, platformChannelSpecifics);
}
