The view model of the <md-file> element (referenced here by view-model.ref="fileInput") contains the native files property value of the wrapped file input control.
Therefore fileInput.files contains an array type FileList which can be read like the value of any native file input control.
It can even be bound to a getter, enhanced with @computedFrom to avoid dirty-checking as shown in this example.
