Cannot find 'FlutterLocalNotificationPlugin' in scope

[joaoribeiro-controlink]

Describe the bug When I try to build my app on xcode it gives me the error "Cannot find 'FlutterLocalNotificationPlugin' in scope"

Sample code to reproduce the problem AppDelegate.swift:

import UIKit
import Flutter
import flutter_local_notifications

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {

    FlutterLocalNotificationPlugin.setPluginRegistrantCallback { (registry) in
        GeneratedPluginRegistrant.register(with: registry)
    }

    if #available(iOS 10.0, *) {
        UNUserNotificationCenter.current().delegate = self as? UNUserNotificationCenterDelegate
    }

    GeneratedPluginRegistrant.register(with: self)
    return super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }
}

# The following line prevents the package from being accidentally published to
# pub.dev using `flutter pub publish`. This is preferred for private packages.

# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43

# Both the version and the builder number may be overridden in flutter
# build by specifying --build-name and --build-number, respectively.
# In Android, build-name is used as versionName while build-number used as versionCode.

Can anyone help me with this??

You've mistyped as you are missing a "s", that is instead of FlutterLocalNotificationPlugin, it should be FlutterLocalNotificationsPlugin as it's plural

Forgot to add that you could've referenced https://github.com/MaikuB/flutter_local_notifications/blob/master/flutter_local_notifications/example/ios/Runner/AppDelegate.swift to copy and paste from
