import 'dart:io' show Platform;
import 'package:flutter/material.dart';
import 'package:flutter_dojah_kyc/flutter_dojah_kyc.dart';
import 'dart:convert';

}

class MyApp extends StatelessWidget {

  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
        title: 'Demo',
        theme: ThemeData(
            // This is the theme of your application.
            //
            // Try running your application with "flutter run". You'll see the
            // application has a blue toolbar. Then, without quitting the app, try
            // changing the primarySwatch below to Colors.green and then invoke
            // "hot reload" (press "r" in the console where you ran "flutter run",
            // or simply save your changes to "hot reload" in a Flutter IDE).
            // Notice that the counter didn't reset back to zero; the application
            // is not restarted.

Other required installations (make sure to follow the instructions in the webview_screen documentation).

Kindly request camera permissions before launching the widget

📘 Request Camera Permission

Kindly declare and request camera permission in the main activity, at your application level - MainActivity/main.dart before launching the SDK

Android configuration

Android

// Add the camera permission: 
<uses-permission android:name="android.permission.CAMERA" />
// Add the modify audio settings permission:
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />

iOS configuration

iOS

permissions_path = '../ios'
pod 'Permission-Camera', :path => "#{permissions_path}/Camera"

Podfile

Kindly include this in Podfile set up.

dart: PermissionGroup.camera PERMISSION_CAMERA=1,

dart: PermissionGroup.microphone PERMISSION_MICROPHONE=1,

dart: PermissionGroup.location PERMISSION_LOCATION=1,

infoplist

info.plist

Add the following keys to your Info.plist file, 
located in <project root>/ios/Runner/Info.plist:

NSCameraUsageDescription - 
  describe why your app needs access to the camera. This is called Privacy - Camera Usage Description in the visual editor.

NSMicrophoneUsageDescription -
  describe why your app needs access to the microphone, if you intend to record videos. This is called Privacy - Microphone Usage Description in the visual editor.

NSLocationWhenInUseUsageDescription - 
    describe why your app needs access to the location, if you intend to verify address/location. This is called Privacy - Location Usage Description in the visual editor.

Run your flutter Project

Step 3: Handle a Successful Enrollment

On successful enrollment, the _onSuccess _callback function that you supplied is called by the SDK. We then return the connected account code to your server.

Alternative configuration instead of Specifying pages Array from the SDK

The main advantage of this feature is to enable you make changes to your widget flow or configuration on Dojah Dashboard herehere instead of rebuilding or modifying the main Flutter Application.
Implementation Example

<span data-testid="SyntaxHighlighter">            
final configObj = {


"widget_id": "your widget ID",
  
  
}
</span>

Kindly use the overall status (response.status (Boolean, i.e true or false)) to ascertain if the request failed or succeeded.

📘 Webhook Notifications

You can receive the same data below (also passed to onSuccess and onError) via a webhook call.

Register your url for webhook calls here and ensure kyc.widget is the service you are subscribed to.

In Config object Kindly set webhook object value to true (Boolean)

Example : webhook : true

By Setting the user-data and country page config enable object to false, The user-data and country page will be removed. Kindly note that this customisation can be implemented only in custom widget type.

📘 How to Exclude or Skip the User data Page

Kindly pass userData inside the DojahKYC constructor class.

Example :

final userData = {  
           "first_name": "JOHN",  
           "last_name": "DOE",  
           "dob": "2022-03-12"  
          };

_dojahKYC = DojahKYC(appId: "appId",  
          publicKey: "p_key",  
          type: "custom",  
          userData: userData, 
          govData: govData, 
          config: configObj,)

📘 How to retrieve the Selfie Photo

There’s a response object that is sent to the client via the widget launcher on success or failure

📘 How to Fix Android File Upload Crash

 STEP 1:


Open the AndroidManifest.xml file located in the android/app/src/main directory of your Flutter project.

Inside the &lt;application&gt; tag, add the following code:
&lt;provider android:name="androidx.core.content.FileProvider" android:authorities="com.example.dojah_kyc.flutter_inappwebview.fileprovider" android:exported="false" android:grantUriPermissions="true"&gt; &lt;meta-data android:name="android.support.FILE_PROVIDER_PATHS" android:resource="@xml/provider_paths" /&gt; &lt;/provider&gt; 
Make sure to replace com.example.dojah_kyc with your application’s package name.


STEP 2: 

Create a new file named provider_paths.xml in the android/app/src/main/res/xml directory (create the xml directory if it doesn’t exist). Add the following code to the provider_paths.xml file:

&lt;paths xmlns:android="http://schemas.android.com/apk/res/android"&gt; &lt;external-path name="external_files" path="." /&gt; &lt;/paths&gt; 



STEP 3: 

Save the changes and rebuild your Flutter application.
By following these steps, you should be able to properly configure the file provider and resolve the “Couldn’t find meta-data for provider” error when selecting files with the file picker in your Flutter application on Android devices.
