Usage

import 'package:flutter/services.dart';
import 'package:flutter_jailbreak_guard/flutter_jailbreak_guard.dart';

Future<bool> isUnsafeDevice() async {
  try {
    return await FlutterJailbreakGuard.isJailbroken;
  } on PlatformException {
    return true;
  }
}

isJailbroken throws PlatformException when the native call fails. The plugin does not choose a fallback value. The app decides whether a failed check blocks the user.

Threading

• iOS runs the check on the main thread. IOSSecuritySuite.amIJailbroken() calls UIApplication.shared.canOpenURL.
• Android runs the check on a background task queue. RootBeer.isRooted reads files and runs su.

iOS URL schemes

IOSSecuritySuite checks jailbreak app URL schemes with canOpenURL. If the app does not list these schemes in LSApplicationQueriesSchemes, iOS returns false for them. The other checks still run.
