Question

我使用 flutter_local_notifications 包来设置通知。我有一个通知列表。就我而言，我的应用程序每 5 秒只显示最后一条通知，但我想显示最后 10 条通知。我该怎么做？

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'],    
          platformChannelSpecifics);
    } else {
      print("no message");
    }
   
  }

这是来自服务器的响应：

在这一行中，您将数据显示为通知

var dataa = (data['data']['data']['data'][0])

并且您通过指定索引 0 仅获取第一个元素

然后你显示通知

要显示所有通知，您必须循环将数据数组扔到任何索引处，然后显示通知..像这样

For(int i = 0; i < data['data']['data']['data'].lemgth; i++) { var data = data['data']['data']['data'][i];

//显示带有数据的通知 }

如何在颤振中显示多个通知
