Barcodescanner configurations

[hamark]

Hi All,

I would like to have access to configurations in barcodescanner.
I thought it was a barcodescanner problem (as you can see in the open issue here)

In summary :

I tried to change ionic-native to include options

    static scan(options?: {
        preferFrontCamera?: boolean;
        showFlipCameraButton?: boolean;
        prompt?: string;
        formats?: string;
        orientation?: string;
    }): Promise<any>;

In my TS I declared barcodescanner

BarcodeScanner.scan({"preferFrontCamera" : true}).then((barcodeData) => {
            // ...
        }, (err) => {
            // ...          
        });

Then in my console when debugging on android phone I've got this error:

BarcodeScanner.scan failure: success callback parameter must be a function

Anyone could help on this ?
