I’ve been exploring how Flutter apps can securely interact with IoT devices using biometrics.

To experiment with this idea, I built a small open-source project:

biometric_iot_bridge

It combines:

• biometric authentication
• secure token generation
• IoT device signaling

The project now includes:

Flutter package on pub.dev

GitHub repository

VS Code extension with snippets

Would love feedback from developers working on Flutter + IoT or authentication flows.
