Flutter onSelectNotification methods in flutter_local_notifications doesn't work - flutter

Question

I'm trying to handle FCM messages in my app when it is in the background. I'm using data messages for that, handle it in global myBackgroundMessageHandler function and create a local notification with flutter_local_notifications plugin, and I receive and show to the user push notification event if the app process killed. But I can't catch the event when user open the app through this push notification. Here is my fcm init:
void initFirebasePushNotifications(){
_firebaseMessaging.configure(
onMessage: (Map<String, dynamic> message) async {
print("onMessage: $message");
Fluttertoast.showToast(msg: "onMessage $message");
// _showItemDialog(message);
},
onBackgroundMessage: myBackgroundMessageHandler,
onLaunch: (Map<String, dynamic> message) async {
print("onLaunch: $message");
Fluttertoast.showToast(msg: "onLaunch $message");
// _navigateToItemDetail(message);
},
onResume: (Map<String, dynamic> message) async {
print("onResume: $message");
Fluttertoast.showToast(msg: "onResume $message");
// _navigateToItemDetail(message);
},
);
_firebaseMessaging.requestNotificationPermissions(
const IosNotificationSettings(
sound: true, badge: true, alert: true, provisional: true));
_firebaseMessaging.onIosSettingsRegistered
.listen((IosNotificationSettings settings) {
print("Settings registered: $settings");
});
_firebaseMessaging.getToken().then((String token) {
assert(token != null);
pushNotificationManager.subscribe(MyApp.user);
print("Push Messaging token: $token");
});
}
And myBackgroundMessageHandler:
import 'dart:io';
import 'dart:math';
import 'package:didiservicekiosk/ui/main/main_screen.dart';
import 'package:flutter/material.dart';
import 'package:flutter_local_notifications/flutter_local_notifications.dart';
import 'package:rxdart/rxdart.dart';
// Streams are created so that app can respond to notification-related events since the plugin is initialised in the `main` function
final BehaviorSubject<ReceivedNotification> didReceiveLocalNotificationSubject =
BehaviorSubject<ReceivedNotification>();
final BehaviorSubject<String> selectNotificationSubject =
BehaviorSubject<String>();
Future<dynamic> myBackgroundMessageHandler(Map<String, dynamic> message) {
print('AppPushs myBackgroundMessageHandler : $message');
_showNotification(message);
return Future<void>.value();
}
Future _showNotification(Map<String, dynamic> message) async {
var pushTitle;
var pushText;
var action;
if (Platform.isAndroid) {
var nodeData = message['data'];
var notification = message['notification'];
pushTitle = nodeData['title'];
pushText = nodeData['body'];
action = nodeData['action'];
} else {
pushTitle = message['title'];
pushText = message['body'];
action = message['action'];
}
print("AppPushs params pushTitle : $pushTitle");
print("AppPushs params pushText : $pushText");
print("AppPushs params pushAction : $action");
var initializationSettingsAndroid = AndroidInitializationSettings('#mipmap/launcher_icon');
var initializationSettingsIOS = IOSInitializationSettings(onDidReceiveLocalNotification:
(int id, String title, String body, String payload) async {
print("onDidReceiveLocalNotification");
didReceiveLocalNotificationSubject.add(ReceivedNotification(
id: id, title: title, body: body, payload: payload));
});
var initializationSettings = InitializationSettings(initializationSettingsAndroid, initializationSettingsIOS);
// #formatter:off
var platformChannelSpecificsAndroid = new AndroidNotificationDetails(
'234', 'Chat notifications', 'Notifications from chat',
playSound: true,
enableVibration: true,
importance: Importance.Max,
priority: Priority.High);
// #formatter:on
var platformChannelSpecificsIos =
new IOSNotificationDetails(presentSound: false);
var platformChannelSpecifics = new NotificationDetails(
platformChannelSpecificsAndroid, platformChannelSpecificsIos);
FlutterLocalNotificationsPlugin _flutterLocalNotificationsPlugin = FlutterLocalNotificationsPlugin();
await _flutterLocalNotificationsPlugin.initialize(initializationSettings, onSelectNotification: selectNotification);
new Future.delayed(Duration.zero, () {
_flutterLocalNotificationsPlugin.show(
Random().nextInt(1000),
pushTitle,
pushText,
platformChannelSpecifics,
payload: 'No_Sound',
);
});
}
Future selectNotification(String payload) async {
// if (payload != null) {
print('selectNotification notification payload: ' + payload);
// }
}
class ReceivedNotification {
final int id;
final String title;
final String body;
final String payload;
ReceivedNotification({
#required this.id,
#required this.title,
#required this.body,
#required this.payload,
});
}
Any suggestions?
