Below steps to setup Accura Scan's SDK to your project.

Note:-

Add flutter_accurascan_mrz under dependencies in your pubspec.yaml file. Usage Import flutter library into file. import 'package:flutter_accurascan_mrz/flutter_accurascan_mrz.dart';

1.Setup Android

Add this permissions into Android’s AndroidManifest.xml file.

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.hardware.camera.autofocus" />

Add it in your root build.gradle at the end of repositories.

allprojects {
   repositories {
       google()
       jcenter()
       maven {
           url 'https://jitpack.io'
           credentials { username 'jp_ssguccab6c5ge2l4jitaj92ek2' }
       }    
    }
}

Add it in your app/build.gradle file.

packagingOptions {
   pickFirst 'lib/arm64-v8a/libcrypto.so'
   pickFirst 'lib/arm64-v8a/libssl.so'
   
   pickFirst 'lib/armeabi-v7a/libcrypto.so'
   pickFirst 'lib/armeabi-v7a/libssl.so'
   
   pickFirst 'lib/x86/libcrypto.so'
   pickFirst 'lib/x86/libssl.so'
   
   pickFirst 'lib/x86_64/libcrypto.so'
   pickFirst 'lib/x86_64/libssl.so'
   
}

2.Setup iOS

1.Install Git LFS using command install git-lfs

2.Run pod install

Add this permissions into iOS Info.plist file.

<key>NSCameraUsageDescription</key>
<string>App usage camera for scan documents.</string>

3.Setup Accura Scan licenses into your projects

Accura Scan has two license require for use full functionality of this library. Generate your own Accura license from here key.license

This license is compulsory for this library to work. it will get all setup of accura SDK.

For Android

Create "assets" folder under app/src/main and Add license file in to assets folder.
- key.license // for Accura Scan OCR
Generate your Accura Scan license from https://accurascan.com/developer/dashboard

For iOS

Place the key.license in your project's Runner directory, and add the licenses to the target.

4.Get license configuration from SDK. It returns all active functionalities of your license.

Setting up License

  Future<void> getMetaData() async{
    try {
      await AccuraOcr.getMetaData().then((value) =>
          setupConfigData(json.decode(value)));
    }on PlatformException{}
    if (!mounted) return;
  }

Error: String

Success: JSON String Response = {

isValid: boolean,

isMRZEnable: boolean

}

5.Method for scan MRZ documents.

Future<void> startMRZ() async {
try {
var config = [
  {"enableLogs": false},
  mrzselected,
];
await AccuraOcr.startMRZ(config)
    .then((value) => {
  setState((){
    dynamic result = json.decode(value);
  })
}).onError((error, stackTrace) => {
});
} on PlatformException {}
