Ionic - Barcode Scanner returns [object Object]

Issue

In Ionic app, I use Barcode Scanner but after scanning it returns: [object Object]

Here is my code:

import { Component } from '@angular/core';
import {BarcodeScanner} from '@ionic-native/barcode-scanner/ngx';


@Component({
  selector: 'app-home',
  templateUrl: 'home.page.html',
  styleUrls: ['home.page.scss'],
})
export class HomePage {  
scannedCode="dd";   
  constructor(private barcodeScanner:BarcodeScanner) {}

   scanCode(){
     this.barcodeScanner.scan().then(barcodeData=>{
         this.scannedCode=barcodeData;
     })
   }

}

Solution

The return type is actually an object. You must get the text encoded value in text property:

scanCode()
{
    this.barcodeScanner.scan().then(
      barcodeData => {
        this.scannedCode=barcodeData.text;
      }
    )
}

Next time when you get [object Object] from some variable, try console loggin it to see ot contents.

console.log(barcodeData);
