When App is Terminated Flutter Callback Events are not working.

[saurav0171]

Whenever app is in terminated state and I hit Voip notification, it successfully hits on my device and shows calling screen. But on accepting call it doesnt hit callback events onDidReceiveIncomingPush and onDidAcceptIncomingCall. Can you please help?

@saurav0171 Thank you for reporting.

onDidReceiveIncomingPush is not called when the app is not running, because app is not yet running when didReceiveIncomingPushWith is called. This wasn't well explained, so I'll add a comment in the next version.

On the other hand, onDidAcceptIncomingCall can be called even if the app is not running. This is because the app is already running when the incoming call screen is displayed for CallKit.

Please make sure the app is calling FlutterIOSVoIPKit.instance.onDidAcceptIncomingCall in the Dart class(e.g.: main.dart) that is called immediately after the app is launched with VoIP notifications.

Thanks for your guidance I appreciate it. Adding to the discussion, I tried calling FlutterIOSVoIPKit.instance.onDidAcceptIncomingCall in main.dart. But unfortunately it didn't work. Steps to reproduce: 1: Voip Notification hits when app is in terminated state. 2: Call picked and it went into app from the beginning and didnt go into FlutterIOSVoIPKit.instance.onDidAcceptIncomingCall method.

Moreover, when app is opened via Voip Notification, it runs from very beginning and FlutterIOSVoIPKit.instance.onDidAcceptIncomingCall didn't call.

Can you please let me know the method which is triggered in dart file when the app first opens via Voip Notifications?

Is the incoming call screen of CallKit displayed at 2? If you see the incoming call screen of CallKit, is your app running after tapped Accept button(swipe when iPhone is locked)?

Can you please let me know the method which is triggered in dart file when the app first opens via VoIP Notifications?

There is no such method. This is because when the VoIP notification arrives, the app isn't running yet, so I can't call the Dart code (If it is possible to call, it will be helpful to give a PR). If your app launches after you accept(swipe or accept button) on the incoming screen I think it will be triggered callbacks in main.dart.

import 'package:flutter/material.dart';
import 'package:flutter_ios_voip_kit/flutter_ios_voip_kit.dart';

void main() {
  runApp(MaterialApp(
    home: Home(),
  ));
}

class Home extends StatefulWidget {
  @override
  _HomeState createState() => _HomeState();
}

class _HomeState extends State<Home> {
  final voIPKit = FlutterIOSVoIPKit.instance;

  @override
  void initState() {
    super.initState();
    voIPKit.onDidAcceptIncomingCall = (String channelId, String callerId) {
      // Use local storage(e.g.: shared_preferences) to save the logs and check if it has been invoked.
    };

    voIPKit.onDidRejectIncomingCall = (String channelId, String callerId) {
      // Use local storage(e.g.: shared_preferences) to save the logs and check if it has been invoked.
    };
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('example'),
      ),
      body: Container(),
    );
  }
}

If onDidReceiveIncomingPush is not called when the app is not running then how to get the payload data in this case. Can you let me know guys the possibilities to get the payload

I have the same problem. Is there any chance to get the payload from app terminated?

[saurav0171]

You need to get this by making channels and communicating with native ios files.

Hey man,

Thank you for your reply. By any chance, do you have some code example on how to do that? I am a bit weak native side..
