Ionic package build not handling all plugins

I’m trying to use the new awesome ionic package service that we were looking for since ionic started

but seems the ionic package doesn’t handle all plugins correctly, I keep getting an error when trying to use cordova.plugins.diagnostic which is properly installed within my projects

when I run “cordova plugin ls” I get below list:
cordova-plugin-console 1.0.1 "Console"
cordova-plugin-device 1.0.1 "Device"
cordova-plugin-geolocation 1.0.1 "Geolocation"
cordova-plugin-splashscreen 2.1.0 "Splashscreen"
cordova-plugin-statusbar 1.0.1 "StatusBar"
cordova-plugin-whitelist 1.0.0 "Whitelist"
cordova.plugins.diagnostic 2.2.3 "Diagnostic"
ionic-plugin-deploy 0.4.0 "IonicDeploy"
ionic-plugin-keyboard 1.0.7 "Keyboard"
phonegap-plugin-push 1.3.0 “PushPlugin”

the code block that fails is:

$ionicPlatform.ready(function () {
    // Hide the accessory bar by default (remove this to show the accessory bar above the keyboard
    // for form inputs)
    if (window.cordova && window.cordova.plugins) {
        if (window.cordova.plugins.Keyboard) {
            cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);
            cordova.plugins.Keyboard.disableScroll(true);
        }
        $rootScope.$on('$stateChangeStart', function (event, toState, toParams, fromState, fromParams) {
            // do something
            try {
                cordova.plugins.diagnostic.isLocationEnabled(function (enabled) {
                    if (enabled) {
