Prevent Screenshots and Screen Recording

To learn how to prevent screenshots and screen recording in your project, follow these steps:

For Android

You don't need to do anything right now, just wait until the end, The idea is that we'll simply use the flutter_windowmanager package to achieve this for Android.

To add the package to your dependencies, run this command in the project terminal:

flutter pub add flutter_windowmanager

To understand, this code will enable the secure mode:

FlutterWindowManager.addFlags(FlutterWindowManager.FLAG_SECURE);

And this code will disable the secure mode:

FlutterWindowManager.clearFlags(FlutterWindowManager.FLAG_SECURE);

For iOS

We will write some Swift native code to achieve this.

- In this repository, go to: ios/Runner/prevent.swift and copy everything.

- Then, open your project in Xcode and go to Runner to create a Swift file, for example, prevent.swift.

- Paste the code that you have copied.

- Add this line inside your ios/Runner/AppDelegate.swift:

ScreenRecordHandler.shared.configure()

- Your AppDelegate will look like this:

 import UIKit
 import Flutter

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

 // Prevent screenshots and recording
    ScreenRecordHandler.shared.configure()
    GeneratedPluginRegistrant.register(with: self)
    return super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }
}

Finishing

- In my repository, go to lib/code/utils/screen_record_shoot_handler.

- Do the same -> create a Dart file wherever you want inside the lib folder and put this code inside it.

- Call preventScreenRecord in initState and disposePreventScreenRecord in dispose like this:

final ScreenRecordHandlerChannel screenRecordHandlerChannel = ScreenRecordHandlerChannel();

@override
 void initState() {
   screenRecordHandlerChannel.preventScreenRecord();
   super.initState();
 }

 @override
 void dispose() {
   screenRecordHandlerChannel.disposePreventScreenRecord();
   super.dispose();
 }

Note: Test your app on a real device, not on an Android emulator or iOS simulator.
