I have implemented Login with Facebook in my Flutter app using flutter_facebook_auth: ^7.0.0. It was working perfectly both for Android and iOS. However, all of a sudden the error below is generated only for iOS in real devices.

-canOpenURL: failed for URL: "fbapi:/" - error: "The operation couldn’t be completed. (OSStatus error -10814.)" false [ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: PlatformException(FAILED, The operation couldn’t be completed. (com.facebook.sdk.core error 8.), null, null)
​

This is the snippet from my pubspec.yaml

environment:
sdk: '>=3.2.5 <4.0.0'

dependencies:
flutter:
sdk: flutter

# to add facebook login
flutter_facebook_auth: ^7.0.0



Snippet from my info.plist

<key>LSApplicationQueriesSchemes</key>
<array>
<string>fbapi</string>
<string>fb-messenger-share-api</string>
</array>


I have set the global iOS platform to 12.0 in my Podfile.

# Uncomment this line to define a global platform for your project
platform :ios, '12.0'


Here is how my AppDelegate.swift file looks:

import UIKit
import Flutter

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
override func application(
_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
) -> Bool {
GeneratedPluginRegistrant.register(with: self)
return super.application(application, didFinishLaunchingWithOptions: launchOptions)
}
}



This is the main portion to handle login with facebook method:

final LoginResult loginResult = await FacebookAuth.instance.login(
//loginTracking: LoginTracking.limited,
//nonce: nonce,
);
if (loginResult.status == LoginStatus.success) {
print('................SUCCESS'); // this is successful
// final AccessToken accessToken = loginResult.accessToken!;
//
final userData = await FacebookAuth.instance.getUserData();// <-- This is where getting the Error.


Error from the log:



Please, kindly help me solve the issue. Thank you all in advance.
