ekyc_id_flutter 1.0.14

A Flutter Plugin to interact with EkycID.

Flutter SDK for EkycID

An easy to use SDK for developing Identity Verification for KYC process. With this SDK, developers can quickly integrate KYC process into their flutter apps.

This Flutter SDK is a wrapper around our Native SDK (Android & iOS).

1. Requirements

---

iOS

• Minimum iOS Deployment Target: 10.0
• Xcode 13 or newer
• Swift 5
• EkycID only supports 64-bit architectures (x86_64 and arm64).

Android

• targetSdkVersion: 32
• compileSdkVersion 32

2. Installation

---

2.1. Flutter Setup

To use this plugin, add ekyc_id_flutter as a dependency in your pubspec.yaml file.

dependencies:
  ...
  ekyc_id_flutter:

2.2 iOS Setup

Step 1: On iOS add the following to your Info.plist

<!-- Camera Access -->
<key>NSCameraUsageDescription</key>
<string>Camera Access for Scanning</string>

<!-- Microphone Access -->
<key>NSMicrophoneUsageDescription</key>
<string>Microphone for playing instructions audio.</string>

Step 2: Go to Project > Runner > Building Settings > Excluded Architectures > Any SDK > armv7 []

Step 3: Make adjustments to your Podfile as shown below.

# add this line:
$iOSVersion = '10.0'

post_install do |installer|
  # add these lines:
  installer.pods_project.build_configurations.each do |config|
    config.build_settings["EXCLUDED_ARCHS[sdk=*]"] = "armv7"
    config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = $iOSVersion
  end
  
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
    
    # add these lines:
    target.build_configurations.each do |config|
      if Gem::Version.new($iOSVersion) > Gem::Version.new(config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'])
        config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = $iOSVersion
      end
    end
    
  end
end

2.3. Android Setup

No extra setup is needed.

3. Usage

---

Step 1: Setup URL to server.

void main() {
  WidgetsFlutterBinding.ensureInitialized();
  EkycIDServices.instance.setURL("YOUR_SERVER_URL");
  runApp(MyApp());
}

Step 2: Setup EkycIDExpress Widget

We expose an easy to use widget called EkycIDExpress. It handles the logic behind identity document scanning and liveness detections for you. You only expects to provide a simple callback to handle the result. Below is how you can use it.

class HomeScreen extends StatefulWidget {
  const HomeScreen({Key? key}) : super(key: key);

  @override
  State<HomeScreen> createState() => _HomeScreenState();
}

class _HomeScreenState extends State<HomeScreen> {

  Future<void> onKYCCompleted({
    required LivenessDetectionResult liveness,
    required DocumentScannerResult mainSide,
    DocumentScannerResult? secondarySide,
  }) async {
    print("== ACCESS RESULTS HERE ==");
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Center(
        child: TextButton(
          onPressed: () async {
            await showCupertinoModalBottomSheet(
              context: context,
              builder: (BuildContext context) {
                return EkycIDExpress(
                  language: Language.KH,
                  onKYCCompleted: onKYCCompleted,
                );
              },
            );
          },
          child: Text("Start KYC"),
        ),
      ),
    );
  }
}

Step 3: Handle the results

In the onKYCCompleted callback, you will have access to an instance of LivenessDetectionResult, and two instances of DocumentScannerResult (One for each side of the document).

Step 3: Match Faces

You can perform a face compare between the face in the document and the face from liveness detection like below.

Future<void> onKYCCompleted({
  required LivenessDetectionResult liveness,
  required DocumentScannerResult mainSide,
  DocumentScannerResult? secondarySide,
}) async {
  
  ApiResult response = await EkycIDServices.instance.faceCompare(
    faceImage1: mainSide.faceImage,
    faceImage2: liveness.frontFace?.image,
  );

  print(response.data?) // match score
}

Step 4: Perform OCR

You can perform OCR on the document image like below.

Future<void> onKYCCompleted({
  required LivenessDetectionResult liveness,
  required DocumentScannerResult mainSide,
  DocumentScannerResult? secondarySide,
}) async {
  
  ApiResult response = await EkycIDServices.instance.ocr(
    image: mainSide.documentImage,
    objectType: mainSide.documentType
  );

  print(response.data?) // response object based on document type
}
