Flutter plugin to enable, disable or toggle screenshot support in your application.
- Disables screenshot and screen recoding on Android and iOS
- Enables screenshot and screen recoding on Android and iOS
- Toggles screenshot and screen recoding on Android and iOS
If you want to prevent user from taking screenshot or recording of your app. You can turn off the screenshot support from the root didChangeAppLifecycleState method.
class _MyHomePageState extends State<MyHomePage> with WidgetsBindingObserver {
final _noScreenshot = NoScreenshot();
AppLifecycleState? _notification;
@override
void didChangeAppLifecycleState(AppLifecycleState state) {
case AppLifecycleState.resumed, :
print("app in resumed");
if(app_secure) _noScreenshot.screenshotOff();
break;
case AppLifecycleState.inactive:
print("app in inactive");
if(app_secure) _noScreenshot.screenshotOff();
break;
case AppLifecycleState.paused:
print("app in paused");
if(app_secure) _noScreenshot.screenshotOff();
break;
case AppLifecycleState.detached:
print("app in detached");
break;
}
}
@override
void initState() {
super.initState();
WidgetsBinding.instance?.addObserver(this);
...
}
@override
void dispose() {
WidgetsBinding.instance?.removeObserver(this);
super.dispose();
}Add no_screenshot to your pubspec.yaml dependencies
call the singleton NoScreenshot.instance anywhere you want to use it.
For instance;
class MyApp extends StatefulWidget {
const MyApp({super.key});
@override
State<MyApp> createState() => _MyAppState();
}
class _MyAppState extends State<MyApp> {
final _noScreenshot = NoScreenshot.instance;
@override
void initState() {
super.initState();
}
@override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
appBar: AppBar(
title: const Text('Plugin example app'),
),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.spaceAround,
children: [
ElevatedButton(
child: const Text('Press to toggle screenshot'),
onPressed: () async {
final result = await _noScreenshot.toggleScreenshot();
print(result);
},
),
ElevatedButton(
child: const Text('Press to turn off screenshot'),
onPressed: () async {
final result = await _noScreenshot.screenshotOff();
print(result);
},
),
ElevatedButton(
child: const Text('Press to turn on screenshot'),
onPressed: () async {
final result = await _noScreenshot.screenshotOn();
print(result);
},
),
],
)),
),
);
}
