Adding ui-utils to Ionic project

I am trying to add ui-mask as a dependency, but after adding lib/ionic/js/masks.min.js and adding:

var opApp = angular.module(‘opApp’, [‘ionic’, ‘ngRoute’, ‘ngProgress’, ‘ui.mask’]);

Error: [$injector:nomod] Module ‘ui.mask’ is not available! You either misspelled the module name or forgot to load it. If registering a module ensure that you specify the dependencies as the second argument.

What am I doing wrong?

As far as I can see ui.mask is included in Angular ui.utils, so you should include that one like described on the ui.utils Github page.

The file you described does not exist in my standard Ionic folder. If you copied it there, let me say that you should not copy it into the folders of the Ionic package package but to lib/whatever/!

I will try that, thanks Simon!
