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

Hi I get this Error in IOS. Please help

Here is my app delegate.swift

import UIKit
import Flutter
import PushKit                     /* <------ add this line */
import flutter_voip_push_notification
import flutter_callkit_voximplant
import CallKit

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate, PKPushRegistryDelegate {
   // Handle incoming pushes
    func pushRegistry(_ registry: PKPushRegistry, didUpdate pushCredentials: PKPushCredentials, for type: PKPushType) {
        // Process the received push
        FlutterVoipPushNotificationPlugin.didUpdate(pushCredentials, forType: type.rawValue);
    }

  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {
    // if #available(iOS 10.0, *) {
    //   UNUserNotificationCenter.current().delegate = self as? UNUserNotificationCenterDelegate
    // }
    GeneratedPluginRegistrant.register(with: self)
    return super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }
    func pushRegistry(_ registry: PKPushRegistry,
                      didReceiveIncomingPushWith payload: PKPushPayload,
                      for type: PKPushType
    ) {
        processPush(with: payload.dictionaryPayload, and: nil)
    }

    func pushRegistry(_ registry: PKPushRegistry,
                      didReceiveIncomingPushWith payload: PKPushPayload,
                      for type: PKPushType,
                      completion: @escaping () -> Void
    ) {
        processPush(with: payload.dictionaryPayload, and: completion)
    }

    private func processPush(with payload: Dictionary<AnyHashable, Any>,
                             and completion: (() -> Void)?
    ) {
        // 3. get uuid and other needed information from payload
        guard let uuidString = payload["uuid"] as? String,
            let uuid = UUID(uuidString: uuidString),
            let localizedName = payload["callerName"] as? String
            else {
                return
        }
        // 4. prepare call update
        let callUpdate = CXCallUpdate()
        callUpdate.localizedCallerName = localizedName
        // 5. prepare provider configuration
        let configuration = CXProviderConfiguration(localizedName: "JPAL")
        // 6. send it to the plugin
        FlutterCallkitPlugin.reportNewIncomingCall(
            with: uuid,
            callUpdate: callUpdate,
            providerConfiguration: configuration,
            pushProcessingCompletion: completion
        )
    }
}
