Is anyone else getting this error when running on Android?

In background mode when the application is considered active the application is not showing call kit on FCXProvider.reportNewIncomingCall(uuid, callUpdate).

When I open the application only then the CallKit is shown.

When the application is considered not active I am sending VoIP notification to PushKit which shows the native CallKit, what is the solution for this?

Hello,

I am a new Flutter developer and I have a list of phone numbers with their respective identifiers(ex: [+211231212343 - John]). I would like to know how to add the caller ID for these phone numbers. Furthermore, when a phone number from the list calls my phone, I want to display the caller's name along with their identifier. Can you help me with this?

Thank you very much.

Flutter stable now supports sound null safety and this package has conflicts with uuid: ^3.0.1.

Is there a way to remove the uuid since it is only used in the example? Is it possible to move the uuid to dev_dependencies

Hi, I'm using PushKit with VoIP push as your example:

# AppDelegate.swift
FlutterCallkitPlugin.sharedInstance.reportNewIncomingCall(
            with: uuid,
            callUpdate: callUpdate,
            providerConfiguration: configuration,
            pushProcessingCompletion: completion
        )

Everything works fine (didDisplayIncomingCall -> provider.performAnswerCallAction) . but when my app is closed and receive voip push, CallKit UI still showing but didDisplayIncomingCall callback didn't get call so i don't have enough information in onAnswerCallback.

Am I missing something ?

Is there is any way to get the call id from the push notification payload ?! @VladimirBrejcha

Hi I get this Error in IOS. Please help

Instance member 'reportNewIncomingCall' cannot be used on type 'FlutterCallkitPlugin'; did you mean to use a value of this type instead?

Here is my app delegate.swift

Hello!
Everything is super, your plugin works perfectly with all the necessary methods in Flutter.
But according to Apple specification reportNewIncomingCallWithUUUID should be called when VoIP push comes, which you have perfectly implemented.

But if the user doesn't accept the call and reject it, the call lasts forever.

Could you add an additional endCall method to your plugin (in the native part) that would end the call with a specific uuid and we would call it at a given timeout. It would be awesome if this method would run through all current calls (like in your hasCallWithUUID method) and end only unanswered calls.

--- RUS ---

Здравствуйте!
Все супер, ваш плагин отлично отрабатывает все необходимые методы во Flutter.
Но по спецификации Apple reportNewIncomingCallWithUUUID должен вызываться по приходу VoIP пуша, что вы замечательно и реализовали.

Но если пользователь не примет вызов и не отклонит его, то звонок длится вечно.

Вы не могли бы добавить в ваш плагин (в нативную часть) дополнительный метод endCall, который бы завершал вызов с определенным uuid, а мы бы вызывали его по заданному таймауту. Было бы просто супер, если бы этот метод пробегал бы по всем текущим вызовам (как в вашем методе hasCallWithUUID) и завершал бы только неотвеченные вызовы.

[FlutterCallKit:ERROR > [ERROR_UNKNOWN_CALLUUID: The operation couldn’t be completed. (com.apple.CallKit.error.requesttransaction error 4.)]]

Are there plans to add docs for handling push notifications in swift?

Here are logs:
flutter: [FlutterCallKit:INFO > FCXProvider.timedOutPerformingAction]
flutter: [FlutterCallKit:INFO > FCXCallObserver.callChanged: 32393681-B759-49C4-9D8A-67A656F4EE7B]
flutter: [FlutterCallKit:INFO > FCXProvider.executeTransaction]
flutter: [FlutterCallKit:INFO > FCXTransaction.getActions]
flutter: [FlutterCallKit:INFO > FCXProvider.FCXEndCallAction]

I can't find a place to manage timeout duration. FCXEndCallAction makes my call close down.
Help please!

I am using this plugin to successfully trigger the CallKit ringing UI upon receiving a PushKit voip notification.

This plugin says to handle the incoming call using the FCXPlugin.didDisplayIncomingCall field in Dart. Answering the call launches the Flutter app UI, but the FCXPlugin.didDisplayIncomingCall function never runs. Interestingly the performAnswerCallAction does run.

I have been unsuccessful in passing information from that function into the Flutter app. I have tried writing and flushing it to disk, as well as SharedPreferences, but the data doesn't appear to be written upon app launch, it is only available in subsequent app launches. I am pretty confused. What is the suggested approach here?

MissingPluginException(No implementation found for method CallController.configure on channel plugins.voximplant.com/flutter_callkit)

where are there two uuids in FCXAnswerCallAction?

when a server send a voip notification to a device with uuid = "X", plugin.didDisplayIncomingCall gets called with uuid = "X". when a user performs answer or end, a callback gets called with callUuid = "X" and uuid = "something else".

what is uuid in FCXAnswerCallAction or FCXEndCallAction and how is it generated? and why is uuid from plugin.didDisplayIncomingCall renamed to callUuid in FCXAnswerCallAction?

This is a really useful package and would greatly help me in my current flutter project. But unfortunately, I need this for android devices. I would really appreciate it if this is made for android SDK as well since a lot of other people may also benefit.

It looks like CallKit will uppercase any UUID i send from the server. I had to lowercase all the UUIDs when sending them back to the server.
I assume it is swift that is doing that transform. Is this correct? If so, this should probably be documented.

UUID(uuidString: callUUID)

accepting the incoming call (audio call) in the example opens the callkit with speaker on. what parameter controls that?

it looks like this:

Thank you very much for the great implementation of the plugin. Beautiful clean code. I really like it.
I still have one problem: I can't figure out how to get the event that occurs when I click on the last calls list item in my phone? This list includes all my voip calls that were made through my app using your plugin (were registered in CallKit).
Clicking on the saved call just opens my app, and I would like to initiate an outgoing call (audio or video, depending on the previous call) in my app.

rus:
Спасибо, большое за отличную реализацию плагина. Красивый чистый код. Мне очень нравится.
У меня осталась одна проблема: я не могу понять, как получить событие, возникающее при нажатии на элемент списка последних звонков в телефоне? В этот список попадают все мои voip вызовы, которые были осуществлены через мое приложение с использованием Вашего плагина (были зарегистрированы в CallKit).
При нажатии на сохраненный вызов просто открывается мое приложение, а мне бы хотелось инициировать в своем приложении исходящий вызов (аудио или видео, в зависимости от предыдущего вызова).

I have an application that I have developed using the dart-sip-ua package with the Asterisk FreePBX server in the backend. Specifically for iOS development, I am using the Voximplant call kit.

I have copied the call service from example this package and implemented it in the application. The problem is that, how do you manage the CallKit in the background?

I am also using Apple Server on the Production environment for sending VoIP Push to the apple device id.

Hi, thanks for good lib, I need help with voip and incoming call, where am I need to put didDisplayIncomingCall function to receive call when app is closed? I checked example but didn't found anything related to that

Hello.
Tell us how to make the application on Flutter run when the phone is locked?
After the user made a pile on the slider and worked out the method "performAnswerCallAction".
In my case, if the phone is not locked, then even if the application is killed from memory, after the answer to the call the application will start and process the incoming call.
All processing is based on WebRTC technology and written in Flutter.
But if the phone is locked, then after the answer to an incoming call the only way to start the application is to press the custom button, enter the unlock code of the screen and only then the application will start.
Is it possible to start the application somehow in the background in the "performAnswerCallAction" handler or even earlier in the "didReceiveIncomingPushWithPayload" handler?

where will I put the handleIncomingCall method to handle calls when I get voip pushes
Future handleIncomingCall(String contactName, String uuid) async {
FCXCallUpdate callUpdate = FCXCallUpdate(localizedCallerName: contactName);
await _provider.reportNewIncomingCall(uuid, callUpdate);
}

First of all, many thanks for your effort in this library!

It's possible to identify the caller number (from landline or mobile number) or CallKit only works for voip applications?

Thank you

This line is shown during the build for android.

I think it will disappear if you delete the android folder from the project.

On iOS 16 devices, CallKit closes after 60 seconds.
In previous versions of iOS (14, 15), it could be displayed for 90 seconds, and then we closed it by ourselves.
We have tried other packages for CallKit, but they still have the same issue.
Have anyone faced the same issue and knows how to bypass it?

UPD: logs that we get when CallKit is finished

flutter: [[FlutterCallKit.INFO](http://fluttercallkit.info/)] FCXProvider > executeTransaction
flutter: [[FlutterCallKit.INFO](http://fluttercallkit.info/)] FCXTransaction > getActions
flutter: [[FlutterCallKit.INFO](http://fluttercallkit.info/)] FCXProvider > FCXEndCallAction
flutter: [[FlutterCallKit.INFO](http://fluttercallkit.info/)] FCXProvider > reportCallEnded
flutter: [[FlutterCallKit.INFO](http://fluttercallkit.info/)] FCXEndCallAction > fulfill
flutter: [[FlutterCallKit.INFO](http://fluttercallkit.info/)] FCXCallObserver > callChanged

I assume, that we are getting declined events from the system.

How to get token to call through voip service?
