AngularJs upon completion of the rendering process

I have been struggling for hours to find a solution without any success. In my angularjs application, I am trying to implement a loading spinner that will display until the page is fully loaded or rendered, especially during state transitions where there is a delay in response. The issue is that even though the click event is registered, no visible feedback is shown to the user indicating whether the page is still loading or not. My application makes ajax calls when the controller is executed. I have attempted various approaches:

Using $stateChangeStart and $viewContentLoaded. This method works well when the views are initially loaded but triggers too early during subsequent state changes due to template caching.
Creating a directive with $timeout. Initially this worked when attached to the body element, however, it does not get called again when switching between states because of nested views/controllers. When attached to the ui-view element, it fires too early.

Are there any other alternatives? Am I missing something important? Is this even achievable?

Thank you

Have you considered implementing the resolve object?

The resolve feature allows you to inject dependencies into your controller and provide custom content or data specific to the state.

https://github.com/angular-ui/ui-router/wiki#resolve

By utilizing the resolve object, you can fetch data before the controller is initialized, ensuring that the data is available when the controller executes and $viewContentLoaded event is triggered:

$stateProvider.state('myState', {
    templateUrl: 'template.html',
    controller: function($scope, myData){
        $scope.myData = myData;
    },
    resolve:{
        myData:  function($http){
            return $http({method: 'GET', url: '/myUrl'})
                .then (function (data) {
                    return doSomeStuffFirst(data);
                }
            );
        }
    }
});

Using resolve in combination with other methods like $routeChangeStart and $viewContentLoaded can greatly improve the functionality of your application.

Add a div element in your web application to designate where the spinner should be displayed.

Include an ng-show="loading"

Prior to making your request, set $scope.loading = true; then implement an AngularJS promise that utilizes either .then() or .finally(), and within the .finally() block, set $scope.loading = false;

This method allows the spinner to be visible while loading and hides it once the loading process is complete.

Check out angular-block-ui, a powerful module designed to handle the display of loading indicators. This versatile tool allows you to block the entire page or specific elements as needed. It works by monitoring http requests and activating blocks only when necessary, ignoring cached requests in the process.
