Yoti Doc Scan Package for Flutter (Unofficial) #
Yoti is an identity checking platform that allows organisations to verify who people are, online and in person. The Yoti Doc Scan SDK allows the user to take a photo of their identifying document which we verify instantly and prepare a response which your system can then retrieve. Further information can be found in the documentation.
Prerequisites #
A supporting Yoti Doc Scan SDK backend installation is required. Learn more about the backend SDK in the Getting Started guide.
Usage #
The SDK exposes a single method, startYoti(), which handles communication between your app and the Yoti app on a user's device.
Import the SDK with:
import 'package:yoti_flutter/yoti_flutter.dart';

Call the startYoti method with your session ID and client session token.
The method accepts two callbacks: one invoked on success, and the other when the result is a failure.
final _yotiFlutterPlugin = YotiFlutter();


try {
var response = await _yotiFlutterPlugin.startYoti(
"<Session ID>",
"<Session Token>");

print(response); // 0 - Result with success

} catch (error) {
// Session Cancelled / Error
print('Platform err: ${error.toString()}');
}

Your error will receive a consistent response with two parameters: code (number) and description (string).
The code is always populated with one of the values in the results table below.
