Right here you go together with my AppDelegate.swift file code:

import UIKit
import Flutter

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {

  override func software(
    _ software: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {
     self.window.makeSecure()
     GeneratedPluginRegistrant.register(with: self)
     return tremendous.software(software, didFinishLaunchingWithOptions: launchOptions)
  }


  // Screenshot Forestall Features


  extension UIWindow {
  func makeSecure() {
      let area = UITextField()
      area.isSecureTextEntry = true
      self.addSubview(area)
      area.centerYAnchor.constraint(equalTo: self.centerYAnchor).isActive = true
      area.centerXAnchor.constraint(equalTo: self.centerXAnchor).isActive = true
      self.layer.superlayer?.addSublayer(area.layer)
      area.layer.sublayers?.first?.addSublayer(self.layer)
    }
  }
