Help with QR Code reader in Cordova

I'm trying to make the app (cordova + onsen) read a QR code and when reading open the link contained in the QR, but instead of opening the link it tries to open a page in the root of the application (file: // android_asset / www / barcode.result).

In the code I just added var ref = window.open('barcode.result', '_blank'); the rest is working normally, it just does not open the link contained in the QR.

Follow my barcode controller code:

app.controller('barcodeController', function( $scope ) {
    $scope.barcode = {
        'result': '',
        'format': '',
        'cancelled': ''
    };

    $scope.startScanner = function() {
        cordova.plugins.barcodeScanner.scan(function (result) {
            $scope.$apply(function() {
                $scope.barcode = {
                    'result': result.text,
                    'format': result.format,
                    'cancelled': result.cancelled
                }
                var ref = window.open('barcode.result', '_blank'); //parte acrescentada
            });
        },
        function (error) {
            alert("Scanning failed: " + error);
        }
    )};
});
