<GridLayout>
    <Cam:CameraPlus row="0" height="{{cameraHeight}}" id="camPlus"
                galleryPickerMode="multiple"
                enableVideo="false" confirmVideo="false"
                saveToGallery="true" showCaptureIcon="true"
                showGalleryIcon="false" showToggleIcon="true"
                showFlashIcon="false" confirmPhotos="false"
                autoSquareCrop="false" insetButtons="true"

                confirmRetakeText="Scatta di nuovo">
