flutter_jailbreak_guard

Detects jailbroken iOS devices and rooted Android devices.

Platform	Engine	Package manager
iOS 13.0+	IOSSecuritySuite 2.2+	Swift Package Manager, CocoaPods
Android API 24+	RootBeer 0.1.2	Gradle

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;
  }
}

API	iOS	Android
`isJailbroken`	`IOSSecuritySuite.amIJailbroken()`	`RootBeer.isRooted`
`isDeveloperMode`	`IOSSecuritySuite.amIRunInEmulator()`	`Settings.Global.DEVELOPMENT_SETTINGS_ENABLED` is on

On iOS, isDeveloperMode does not read the iOS Developer Mode setting. It returns true when the app runs in the simulator.

Failure handling

If the native result is null, both APIs return true.
If the native call fails, both APIs throw PlatformException. The app decides whether a failed check blocks the user.

Migration from flutter_jailbreak_detection_plus

flutter_jailbreak_detection_plus	flutter_jailbreak_guard
`FlutterJailbreakDetectionPlus.jailbroken`	`FlutterJailbreakGuard.isJailbroken`
`FlutterJailbreakDetectionPlus.developerMode`	`FlutterJailbreakGuard.isDeveloperMode`

The detection engines and the fallback values are the same.

What this package changes

It keeps the behavior of flutter_jailbreak_detection_plus. The two APIs call the same engine methods and return true when the result is missing.
It adds Swift Package Manager support. flutter_jailbreak_detection_plus and flutter_jailbreak_detection support only CocoaPods.
It runs the Android checks on a background task queue. RootBeer.isRooted reads files and runs su. The packages with the same API run it on the platform thread.
It pins IOSSecuritySuite to 2.2 or later. flutter_jailbreak_detection_plus does not pin a version. jailbreak_root_detection stays on 1.9.x.
It returns true when the result is missing. jailbreak_root_detection and safe_device return false, so a failed check lets the user continue.
It has Dart unit tests, a Kotlin unit test, and integration tests.

Difference from root_jailbreak_guard

root_jailbreak_guard has the same API as flutter_jailbreak_detection_plus, but its checks are different.

Check	flutter_jailbreak_guard	root_jailbreak_guard
iOS jailbreak	`amIJailbroken()`	`amIJailbroken()` or `amIDebugged()`
iOS developer mode	`amIRunInEmulator()`	`amIRunInEmulator()` or `amIDebugged()`
Android root	`isRooted`	`isRooted` or `isRootedWithBusyBoxCheck`

root_jailbreak_guard returns true for jailbreak when a debugger is attached to the iOS app. This occurs when you run the app from Xcode. flutter_jailbreak_guard returns the same result as flutter_jailbreak_detection_plus.

When to use another package

If you need more signals, such as Frida, debugger, tampering, or mock location, use jailbreak_root_detection, safe_device, or freerasp.
If you need a full runtime protection SDK with threat callbacks, use freerasp.
If your app supports iOS earlier than 13.0 or Android API earlier than 24, this package does not support it.

Threading

iOS runs the checks on the main thread. IOSSecuritySuite.amIJailbroken() calls UIApplication.shared.canOpenURL.
Android runs the checks 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.
