Bonjour, j'ai suivi le cours et lu toute la doc ionic mais à aucun moment on ne ma indiqué ou écrire le code du plugin

J'ai donc installé le plugin en faisant:

$ ionic cordova plugin add cordova-plugin-qrscanner

$ npm install --save @ionic-native/qr-scanner

Mais après il y a ce code et je ne sait pas ou le mettre ni comment m'en servir, merci

import { QRScanner, QRScannerStatus } from '@ionic-native/qr-scanner';


constructor(private qrScanner: QRScanner) { }

...

// Optionally request the permission early
this.qrScanner.prepare()
  .then((status: QRScannerStatus) => {
     if (status.authorized) {
       // camera permission was granted


       // start scanning
       let scanSub = this.qrScanner.scan().subscribe((text: string) => {
         console.log('Scanned something', text);

         this.qrScanner.hide(); // hide camera preview
         scanSub.unsubscribe(); // stop scanning
       });

     } else if (status.denied) {
       // camera permission was permanently denied
       // you must use QRScanner.openSettings() method to guide the user to the settings page
       // then they can grant the permission from there
     } else {
       // permission was denied, but not permanently. You can ask for permission again at a later time.
     }
  })
  .catch((e: any) => console.log('Error is', e));
