flutter - 如何在列表 Flutter 中保存通知

Question

我实现了通知插件，我可以从服务器获取警报列表。如您所见，我正在尝试获取最后一个警报。我想获取最后 10 个警报，而不仅仅是一个并将其保存在列表中。

之后我想向用户显示所有 10 个通知。

这是我的代码：

Future<void> repeatNotification() async {
    var androidChannelSpecifics = AndroidNotificationDetails(
      'CHANNEL_ID 3',
      'CHANNEL_NAME 3',
      "CHANNEL_DESCRIPTION 3",
      playSound: true,
      importance: Importance.max,
      priority: Priority.high,
      sound: RawResourceAndroidNotificationSound('notification'),
      styleInformation: DefaultStyleInformation(true, true),
    );
    var iosChannelSpecifics = IOSNotificationDetails();
    var platformChannelSpecifics = NotificationDetails(
        android: androidChannelSpecifics, iOS: iosChannelSpecifics);
    SharedPreferences localStorage = await SharedPreferences.getInstance();
    String token = localStorage.getString('access_token');
    Map<String, String> headers = {
      'Content-type': 'application/json',
      'Accept': 'application/json',
      'Authorization': 'Bearer $token'
    };
    var response =
        await http.get(Uri.parse(ApiUtil.GET_ALERT), headers: headers);
    var data = json.decode(response.body);
    var dataa = (data['data']['data']['data'][0]);
    if (data['status'] == 200) {
      flutterLocalNotificationsPlugin.show(
          0,
          dataa['boxName'],
          dataa['alert_description'],
          //  RepeatInterval.everyMinute,
          platformChannelSpecifics);
    } else {
      print("no message");
    }
   
  }

这是来自服务器的响应：

                }
            ],

我怎样才能实现呢？

尝试在通知列表上循环并为此列表中的每个项目推送通知

像这样：

var response =
        await http.get(Uri.parse(ApiUtil.GET_ALERT), headers: headers);
    var data = json.decode(response.body);
    List notificationsList = data['data']['data']['data'];
    if (data['status'] == 200) {
      notificationsList.forEach((notification) {
        flutterLocalNotificationsPlugin.show(
            Random.nextInt(1000),
            notification['boxName'],
            notification['alert_description'],
            //  RepeatInterval.everyMinute,
            platformChannelSpecifics);
      });
    } else {
      print("no message");
    }
