Flutter隔离在应用被杀死时未显示通知

Question

当使用该应用程序被杀死时，使用Flutter隔离程序包的Flutter隔离程序不会显示通知。

[将隔离包与dart：isolate结合使用，不起作用。

import 'dart:async';
import 'dart:isolate';


import 'package:flutter/material.dart';
import 'package:flutter_isolate/flutter_isolate.dart';
'package:flutter_local_notifications/flutter_local_notifications.dart';
FlutterLocalNotificationsPlugin flutterLocalNotificationsPlugin = new FlutterLocalNotificationsPlugin();

Future onSelectNotification(String payload) async {
  if (payload != null) {
    debugPrint('notification payload: ' + payload);
  }
}

  void isolated(String args) async {
    Timer.periodic(new Duration(seconds: 10), (Timer t) => print('hi!'));
    Timer.periodic(new Duration(seconds: 10), (Timer y) async
    {
      var androidPlatformChannelSpecifics = AndroidNotificationDetails(
          'your channel id', 'your channel name', 'your channel description',
          importance: Importance.Max,
          priority: Priority.High,
          ticker: 'ticker');
      var iOSPlatformChannelSpecifics = IOSNotificationDetails();
      var platformChannelSpecifics = NotificationDetails(
          androidPlatformChannelSpecifics, iOSPlatformChannelSpecifics);
      await flutterLocalNotificationsPlugin.show(
          0, 'plain title', 'plain body', platformChannelSpecifics,
          payload: 'item x');
    });

}
  void main() async {

    // initialise the plugin. app_icon needs to be a added as a drawable resource to the Android head project
    // If you have skipped STEP 3 then change app_icon to @mipmap/ic_launcher

    var initializationSettingsAndroid =
    new AndroidInitializationSettings('appicon');
    var initializationSettingsIOS = new IOSInitializationSettings();
    var initializationSettings = new InitializationSettings(
        initializationSettingsAndroid, initializationSettingsIOS);
    flutterLocalNotificationsPlugin.initialize(initializationSettings,
        onSelectNotification: onSelectNotification);
    isolated("hi");
  }

上面的代码是当状态类终止且不再存在时系统被杀死时系统看到的内容。如果我们可以运行上面的代码，则当应用在Android和iOS中被用户杀死并且状态类不再存在时，隔离仍将起作用。

提前感谢。
