Overview
About this SDK
The Unico Check Flutter SDK enables you to quickly build a great experience in your native Android/iOS applications. A component is provided to allow you to frictionlessly capture images in your application through the use of modern camera opening mechanisms as well as computer vision algorithms.
Apart from abstracting all the complexity related to any device-specific nuances, the SDK also helps to correctly frame the images, optimizing its capture, aiming to increase the accuracy in the response of the biometric engine.

Available features
The following features are available in the SDK:
- Face Capture;
- Manual image capture;
- Smart Camera image capture;
- Image capture with liveness-proven (Smartlive with interaction FaceTec);
- Document Capture;
Older phones may not support some features required by the computer vision technologies used in the Smart Camera feature. In these cases, the Manual Camera mode is triggered as a fallback, allowing the user to manually capture his face image.
How it works
The client-side SDK is responsible for simplifying your integration with Unico Check, abstracting all the complexity related to camera manipulation and image capture.
After a successful capture, the SDK returns an object that must be sent to the REST APIs to complete the biometric validation.
- Users accesses your application;
- Through the SDK, your application requests the image capture frame (as configured in your application);
- Your application renders the image capture frame of the Unico Check in a pre-configured placeholder;
- Your application captures the image (automatically, manually or in Liveness-proven mode), generating a
JWTtoken; - Your application sends the
JWTto your server; - Your server call the REST APIs of Unico Check to validate the images (Documentation of the APIs can be found at this link)
- The server returns the biometric validation response, to be forwarded to your application;
