How to display multiple notifications in flutter

Question

I use flutter_local_notifications package to set notifications. I have a list of notification.In my case, my app shows only the last notification every 5 seconds , but I want to show the last 10 notifications. How can I do this ?

this my code :

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");
    }
   
  }

and this the response from the server :

    "code": 0,
    "message": " success",
    "data": {
        "data": {
            "current_page": 1,

In this line you are taking the data to display as notification

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

And you are taking only the first element by specifing index 0

Then you show the notification

To show all the notification you have to cycle throw your data array at any index then show the notification.. something like this

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

//Display notification with data }
