cordovaBarcodeScanner stoped working: empty object

Hi everybody,

I’m in troubles because some days ago i successfully integrated $cordovaBarcodeScanner in my Ionic App and it worked great.

$scope.scanBarcode = function() {
    $cordovaBarcodeScanner.scan().then(function(imageData) {
    	//EAN CODE READED: imageData.text
        console.log("Barcode Format -> " + imageData.format);
        $ = imageData.text;
    }, function(error) {
        console.log("An error happened -> " + error);

Today, it started not working. No errors happens, but the camera is not loading. I placed a console.log($cordovaBarcodeScanner) and it returns an empty object “{}” :-?

And this is my app.js file:

Any idea?

I solved removing and re-adding the barcode plugin to my project.
