iOS Kill state don't showing call kit!

[Technozer]

i was using view call kit firebase FCM to send notification to send notificaion using FCM -> FirebaseMessaging.onMessage.listen -> flutter_call_incoming

And also when app was forgroung state view call kit on after app was kill auto cut call only this two issue face on iOS kill state.

Call kit is not showing even though notification is received when in kill state only iOS. otherwise andorid all stack view call kit and iOS Only background and forgrond working fine.

iOS AppDelegte code :

import UIKit import FirebaseCore import Flutter import Firebase import CallKit import AVFAudio import PushKit import flutter_callkit_incoming

@UIApplicationMain @objc class AppDelegate: FlutterAppDelegate, PKPushRegistryDelegate, CallkitIncomingAppDelegate { // var window : UIWindow?

For iOS, you need to send voip push notification not just notification. voip push can wake up app when app is in terminated state

[Technozer]

Can you share a detailed demo? How to send voip notifications on the app side and also receive side view call kill and how to set up voip notification?

Now facing new issue SwiftFlutterCallKitIncomigPlugin file Error: uuid is nil

@objc public func showCallkitIncoming(_ data: Data, fromPushKit: Bool) { self.isFromPushKit = fromPushKit if(fromPushKit){ self.data = data }

    var handle: CXHandle?
    handle = CXHandle(type: self.getHandleType(data.handleType), value: data.getEncryptHandle())

    let callUpdate = CXCallUpdate()
    callUpdate.remoteHandle = handle
    callUpdate.supportsDTMF = data.supportsDTMF
    callUpdate.supportsHolding = data.supportsHolding
    callUpdate.supportsGrouping = data.supportsGrouping
    callUpdate.supportsUngrouping = data.supportsUngrouping
    callUpdate.hasVideo = data.type > 0 ? true : false
    callUpdate.localizedCallerName = data.nameCaller

    initCallkitProvider(data)

    let uuid = UUID(uuidString: data.uuid)

    configurAudioSession()
    guard self.sharedProvider != nil else {
        print("Error: sharedProvider is nil")
        return
    }

    guard let uuid = uuid else {
        print("Error: uuid is nil")
        return
    }
    self.sharedProvider?.reportNewIncomingCall(with: uuid, update: callUpdate) { error in
        if(error == nil) {
            self.configurAudioSession()
            let call = Call(uuid: uuid, data: data)
            call.handle = data.handle
            self.callManager.addCall(call)
            self.sendEvent(SwiftFlutterCallkitIncomingPlugin.ACTION_CALL_INCOMING, data.toJSON())
            self.endCallNotExist(data)
        }
    }
}

Error: uuid is nil

also using showCallkitIncoming( uuid: const Uuid().v4(), title: message.data['doctorName'], body: message.data['body'], profile: message.data['doctorProfile'], callType: callType, customRoomId: customRoomId, videoCallId: message.data['videoCallId'], appointmentPatientName: message.data['appointmentPatientName'], isVideoCall: message.data['isVideoCall'], );

You have to make sure that the data you transmit has UUID.
