 * @name Barcode Scanner
 * @description
 * The Barcode Scanner Plugin opens a camera view and automatically scans a barcode, returning the data back to you.

 *
 * @usage
 * ```typescript
 * import { BarcodeScanner } from '@ionic-native/barcode-scanner/ngx';
 *
 * constructor(private barcodeScanner: BarcodeScanner) { }
 *
 * ...
 *
 *
 * this.barcodeScanner.scan().then(barcodeData => {
 *  console.log('Barcode data', barcodeData);
 * }).catch(err => {
 * 	console.log('Error', err);
 * });
 * ```
