is_device_secure 2.0.2

This plugin can check security status of the device.

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.
