Scan object is underfined in cordova-plugin-document-scanner

I am trying to cordova-plugin-document-scanner in my ionic application. but in my device ready function, I cannot access the global scan object. Here is the code

this.platform.ready().then((readySource) => {
  console.log('Platform ready from', readySource);
  // Platform now ready, execute any required native code
 console.log(scan);      
});

and here is the exception

Error: Uncaught (in promise): ReferenceError: 'scan' is not defined
ReferenceError: 'scan' is not defined
at Anonymous function (http://localhost:8100/build/main.js:839:13)
at t.prototype.invoke (http://localhost:8100/build/polyfills.js:3:14879)

at Anonymous function (http://localhost:8100/build/polyfills.js:3:20233)

Can anybody help me where I am going wrong?

nice seeing you here :)

Just linking the solved github issue here, for future users.

Here are the steps :-

1) Create blank Ionic Project in terminal ionic start myproject blank

2) Add plugin to project ionic cordova plugin add cordova-plugin-document-scanner

3) Now navigate to E:\myproject\src\app\app.component.ts - add declare var scan; above @Component({.. - then inside platform.ready().then(() => { } function add the following function as shown in readme.

scan.scanDoc(1, onSuccess, onFail);

function onSuccess(imageURI) {
    //var image = document.getElementById('myImage');
    //image.src = imageURI;
}

function onFail(message) {
    alert('Failed because: ' + message);
}

4) Then in terminal ionic cordova run android

5) Also don't forget to read the documentation and the other solutions to issues if you run into trouble.

Have a nice day all of you :)
