Is it possible to inject scope or controller during running ?
or any other advice to dynamically inject services into controller ?

Application.controller('IndexController', function($scope){



    // some actions



    if(someconditions) {

            $scope.$inject = [someServiceName];

            // and here i want to use service methods 

    }



});

Thanks in advance

A service can be dynamically injected (by name) into a controller using the $injector. Being able to inject services via controller arguments is just a convenience that Angular provides. Under the hood, the $injector is used by Angular to retrieve object instances. But we can use the $injector ourselves also.

function MyCtrl($scope, $injector) {

  $scope.doSomething = function(someService) {

    var service = $injector.get(someService)  // someService contains the name of a service

    service.value += 10

}

Fiddle.
