Implementation Guide

Authentication

A unique access token should be created upon each SDK entry. In order to generate an access token, please refer to Valify's Authentication Documentation.

Security Warning: For improved security, consider implementing the access token fetching logic outside the Activity. This helps keep sensitive credentials secure and reduces potential exposure within the Activity/Fragment code.

Importing

Import the module’s function in your file using the following line

import 'package:vidvocr_flutter_plugin/vidvocr_flutter_plugin.dart';

Configurations

The plugin builder is separated into two components.

Required Configurations

Initialize the required parameters as follows while adding the required configurations

  final String baseURL = ' '; //put your acctual base url here
  final String bundleKey = ' '; //put your actual bundle key here
  final String accessToken = ' '; //put your actual access token here

Optional Configurations

Initialize the required parameters as follows while adding the desired configurations

final String language = "<insert_language>"; // "en" is set as default
final bool document_verification = <boolean>; // false is set as default
final bool collect_user_info = <boolean>; // false is set as default
final bool document_verification_plus = <boolean>; // false is set as default
final bool advanced_confidence = <boolean>; // false is set as default
final bool profession_analysis = <boolean>; // false is set as default
final bool review_data = <boolean>; // default is true
final bool preview_captured_image = <boolean>; //default is false
final bool manual_capture_mode = <boolean>; //default is false
final bool capture_only_mode = <boolean>; // default is false
final String primary_color = ”<hex_color_code>”; //default is valify default color
final bool enable_logging= <boolean>; // default false

Configurations Breakdown

This section shows the breakdown of all optional builder configurations.

1. The following line is where the user interface language is set.

final String language = "<insert_language>"; // ["ar" or "en"] 

The currently supported languages are Arabic and English

1. If the following line is set to true, the SDK will return document verification plus data

final bool document_verification_plus = <boolean>;

1. If the following line is set to true, the SDK will return advanced confidence data

final bool advanced_confidence = <boolean>;

1. If the following line is set to true, the captured image will be displayed for the user.

final bool preview_captured_image = <boolean>;

1. If the following line is set to true, the SDK will automatically enable manual capture if it detects that the user is unable to autocapture card.

final bool manual_capture_mode = <boolean>;

1. If the following line is set to true, a screen is added to the user flow that displays the images captured and the OCR result to the user.

final bool review_data = <boolean>;

1. If the following line is set to true, the SDK purely performs image capturing and only returns these images in the SDK response.

final bool capture_only_mode = <boolean>;

1. The following line is optional and can be used to receive event logs from the SDK experience to be used for user behavior analysis.

final bool enable_logging= <boolean>;

1. The following line is optional and can be used to set your company's branding color to the SDK's user interface.

final String primaryColor = ”<hex_color_code>”;

Parameter Declaration

Declare the SDK parameters with the configuration variables previously created

Map<String, dynamic> params = {
  "base_url": baseURL,
  "access_token": accessToken,
  "bundle_key": bundleKey,
  "language": language,
  "document_verification": document_verification,
  "review_data": review_data,
  "capture_only_mode": capture_only_mode,
  "manual_capture_mode": manual_capture_mode,
  "preview_captured_image": preview_captured_image,
  "primary_color": "primary_color",
  "enable_logging": enable_logging,
  "collect_user_info": collect_user_info,       
  "advanced_confidence": advanced_confidence,     
  "profession_analysis": profession_analysis,     
  "document_verification_plus": document_verification_plus
};

Start the SDK

Use the following code snippet to run the plugin

    try {
      final String? result = await VidvocrFlutterPlugin.startOCR(params);
        //handle logic to use the liveness response depending on the state    
    } on PlatformException catch (e) {
        //catch errors here
    }
