Using ui-router with Bootstrap-ui modal

Here is a provider that improves @nathan-williams solution by passing resolve section down to the controller:

.provider('modalState', ['$stateProvider', function($stateProvider) {
  var provider = this;

  this.$get = function() {
    return provider;
  }

  this.state = function(stateName, options) {
    var modalInstance;

    options.onEnter = onEnter;
    options.onExit = onExit;
    if (!options.resolve) options.resolve = [];

    var resolveKeys = angular.isArray(options.resolve) ? options.resolve : Object.keys(options.resolve);
    $stateProvider.state(stateName, omit(options, ['template', 'templateUrl', 'controller', 'controllerAs']));

    onEnter.$inject = ['$uibModal', '$state', '$timeout'].concat(resolveKeys);
    function onEnter($modal, $state, $timeout) {
      options.resolve = {};

      for (var i = onEnter.$inject.length - resolveKeys.length; i < onEnter.$inject.length; i++) {
        (function(key, val) {
          options.resolve[key] = function() { return val }
        })(onEnter.$inject[i], arguments[i]);
      }

      $timeout(function() { // to let populate $stateParams
        modalInstance = $modal.open(options);
        modalInstance.result.finally(function() {
          $timeout(function() { // to let populate $state.$current
            if ($state.$current.name === stateName)
              $state.go(options.parent || '^');
          });
        });
      });
    }

    function onExit() {
      if (modalInstance)
        modalInstance.close();
    }

    return provider;
  }
}]);

function omit(object, forbidenKeys) {
  var prunedObject = {};
  for (var key in object)
    if (forbidenKeys.indexOf(key) === -1)
      prunedObject[key] = object[key];
  return prunedObject;
}

then use it like that:

.config(['modalStateProvider', function(modalStateProvider) {
  modalStateProvider
    .state('...', {
      url: '...',
      templateUrl: '...',
      controller: '...',
      resolve: {
        ...
      }
    })
}]);

I answered a similar question, and provided an example here:

Modal window with custom URL in AngularJS

Has a complete working HTML and a link to plunker.

The $modal itself doesn't have a close() funcftion , I mean If you console.log($modal) , You can see that there is just an open() function.

Closing the modal relies on $modalInstance object , that you can use in your modalController.

So This : $modal.close(result) is not actually a function!

Notice : console.log($modal); ==>> result :

          Object { open: a.$get</k.open() }
           // see ? just open ! , no close !

There is some way to solve this , one way is :

First you must define a controller in your modal like this :

   $modal.open({
      templateUrl: 'components/new-item/new-item.html',
      controller:"MyModalController"
    });

And then , Later on , :

    app.controller('MyModalController',function($scope,$modalInstance){
      $scope.closeMyModal = function(){
       $modalInstance.close(result);
        }
       // Notice that, This $scope is a seperate scope from your NavbarCtrl,
       // If you want to have that scope here you must resolve it

   });
