🔒 App Security SDK for Flutter #

App Security SDK is a Flutter plugin that helps you secure your application by detecting unsafe environments like rooted/jailbroken devices, cloned apps, piracy, debugging, and more. It also validates the app’s integrity, detects VPN usage, and ensures the app is installed from trusted sources.

✨ Features #

- ✅ Root/Jailbreak Detection
    Detect if the device is rooted (Android) or jailbroken (iOS).

    Detect whether the device is in developer mode or being debugged.

- ✅ Piracy Detection
    Validate app integrity and detect pirate apps using Kevlar.

- ✅ Install Source Verification
    Ensure the app was installed from trusted sources like Play Store, App Store, or TestFlight.

- ✅ Clone Detection
    Detect cloned or dual apps using sandbox validation.

- ✅ Device Identifier Access
    Fetch Device ID (Android ID) and Identifier for Vendor (iOS).
