is_device_secure
A Flutter plugin that checks whether the device is secure — for example, if it has a secure lock screen setup (PIN, pattern, password, fingerprint, etc.). It can also provide platform information for debugging or device checks.
This plugin helps developers ensure their app is running on a device that enforces basic security measures, which is especially useful for apps that handle sensitive data such as banking, payment, or enterprise apps.
Features
- ✅ Check if the device is secured with PIN, password, or biometric lock
- 🧩 Works on Android and iOS
- ⚡ Lightweight and easy to use
- 🔒 Helps enforce security policies before granting access
Installation
Add this line to your app’s pubspec.yaml under dependencies:
dependencies:
is_device_secure: ^<latest_version>
Then, run:
flutter pub get
Usage
final isSecure = await IsDeviceSecure.secure;
print("Is device secure: $isSecure");
Output
Example output on a secured device:
Is device secure: true
Example output on an unsecured device (no lock screen):
Is device secure: false
