Usage

Import the package

To use this plugin, follow the plugin installation instructions.

Android

Android detects external storage to determine if a screenshot has occurred. So you need permission to external storage. Use the following links if necessary.

Specify your API key in the application manifest android/app/src/main/AndroidManifest.xml:

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

iOS

No action is required. Screenshots can be detected by the plug-in itself.

Use the plugin

Add the following import to your Dart code:

import 'package:screenshot_callback/screenshot_callback.dart';

Initialize ScreenshotCallback with the scopes you want:

!!! It must be created after permission is granted. (Android only)

ScreenshotCallback screenshotCallback = ScreenshotCallback();

addListener

Then invoke addListener method of ScreenshotCallback. Add custom functions that you want to excute after detect screenshot. e.g:

screenshotCallback.addListener(() {
  //Void funtions are implemented
  print('detect screenshot');
});

dispose

You need to call dispose method to terminate ScreenshotCallback before you exit the app e.g:

screenshotCallback.dispose();
