Getting started

First, add zo_screenshot as a dependency in your pubspec.yaml file

dependencies:
  flutter:
    sdk: flutter
  zo_screenshot : ^[version]

Import the package

import 'package:zo_screenshot/zo_screenshot.dart';

Usage

Disabling ScreenShot

final _zoScreenshotPlugin = ZoScreenshot();
_zoScreenshotPlugin.disableScreenShot();

Enabling Screenshot

final _zoScreenshotPlugin = ZoScreenshot();
_zoScreenshotPlugin.enableScreenshot();

Listen To Screenshot Event

final _zoScreenshotPlugin = ZoScreenshot();

_zoScreenshotPlugin.startScreenshotListner(
  screenShotcallback: () {
    print("Screenshot taken");
  },
);

Secure Specific Routes

Financial apps like Google Pay (GPay) prevent sensitive screens from being recorded or captured. You can implement similar security measures in your app by blocking screenshots and screen recordings on specific routes. The approach depends on your navigation style—whether you're using named routes or class-based navigation.

For Named Route

return MaterialApp(
  navigatorObservers: [
    ZoNavigatorObserver(
      navigationStyle: NavigationStyle.namedRoute,
      secureNamedRouteList: ["/secureRoute"],
    ),
  ],
  routes: {
    "/secureRoute": (context) => const SecureRoute(),
    "/nonSecureRoute": (context) => NonSecure(),
  },
  home: Scaffold(
    appBar: AppBar(
      centerTitle: true,
      title: const Text('Zo Screenshot Example'),
    ),
    body: Example(),
  ),
);

For Class Route

return MaterialApp(
  navigatorObservers: [
    ZoNavigatorObserver(
      navigationStyle: NavigationStyle.classRoute,
      secureClassRouteList: [SecureRoute],
    ),
  ],
  home: Scaffold(
    appBar: AppBar(
      centerTitle: true,
      title: const Text('Zo Screenshot Example'),
    ),
    body: Example(),
  ),
);

Show Preview While App is in Background

Wrap with ZoScreenShotWrapper

ZoScreenShotWrapper(
  disableScreenShot: true,
  backgroundPreviewWidget: Container(
    decoration: BoxDecoration(
      gradient: LinearGradient(
        begin: Alignment.topCenter,
        end: Alignment.bottomCenter,
        colors:[Colors.grey[300]!, Colors.grey],
      ),
    ),
    width: double.infinity,
    height: double.infinity,
    child: Center(
    child: Icon(Icons.lock, size: 50, color: Colors.white),
    ),
  ),
  child: Scaffold(
    appBar: AppBar(
      title: const Text('Plugin example app'),
    ),
    body: Example(),
  ),
);
