Installation

Add this to your package's pubspec.yaml file:

dependencies:
  security_plus: ^3.0.1

Platform Setup

Android

1.Add the following permissions to your AndroidManifest.xml file:

<manifest xmlns:android="http://schemas.android.com/apk/res/android">
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
</manifest>

2.Add permission_handler for runtime permission management:

dependencies:
  permission_handler: ^10.4.3

iOS

Add the following to your Info.plist file:

<key>NSLocationWhenInUseUsageDescription</key>
<string>This app needs access to location when open to verify device security.</string>

Usage

Import the package

import 'package:security_plus/security_plus.dart';
import 'package:permission_handler/permission_handler.dart';

Handle Permissions and Security Checks

Future<void> checkDeviceSecurity() async {
  // Request location permission first
  if (Platform.isAndroid) {
    final status = await Permission.location.request();
    if (!status.isGranted) {
      // Handle permission denied
      return;
    }
  }

  // Perform security checks
  try {
    final isRooted = await SecurityPlus.isRooted;
    final isEmulator = await SecurityPlus.isEmulator;
    final isDevelopmentMode = await SecurityPlus.isDevelopmentModeEnable;
    final isMockLocation = await SecurityPlus.isMockLocationEnabled;
    final isExternalStorage = await SecurityPlus.isOnExternalStorage;

    // Handle security check results
    if (isRooted || isEmulator || isMockLocation) {
      // Handle security risks
    }
  } catch (e) {
    // Handle errors
  }
}

Individual Security Checks

Root Detection

try {
  bool isRooted = await SecurityPlus.isRooted;
  if (isRooted) {
    // Handle rooted device
  }
} catch (e) {
  // Handle errors
}

Emulator Detection

try {
  bool isEmulator = await SecurityPlus.isEmulator;
  if (isEmulator) {
    // Handle emulator detection
  }
} catch (e) {
  // Handle errors
}

Development Mode Check

try {
  bool isDevelopmentMode = await SecurityPlus.isDevelopmentModeEnable;
  if (isDevelopmentMode) {
    // Handle development mode
  }
} catch (e) {
  // Handle errors
}

Mock Location Check

try {
  bool isMockLocation = await SecurityPlus.isMockLocationEnabled;
  if (isMockLocation) {
    // Handle mock location
  }
} catch (e) {
  // Handle errors
}

External Storage Check

try {
  bool isOnExternalStorage = await SecurityPlus.isOnExternalStorage;
  if (isOnExternalStorage) {
    // Handle external storage detection
  }
} catch (e) {
  // Handle errors
}

Security Features

Root Detection Mechanisms

The plugin employs multiple layers of root detection:

  1. RootBeer Integration: Uses the advanced RootBeer library for base root detection
  2. Frida Detection: Actively searches for Frida-related processes and libraries
  3. File System Checks: Scans for common root-related files and directories
  4. Package Analysis: Detects known root management applications
  5. Runtime Integrity: Checks for system modifications and hooks

Anti-Tampering Protection

  • Process monitoring for known tampering tools
  • Library injection detection
  • System property verification
  • Runtime integrity checks
