How to $inject dynamically dependence in a controller

javascript angularjs dependency-injection

Don't call angular.injector() -- this creates a new injector. Instead, inject the already-created $injector into your controller and use it:

So instead of:

var algoController = function($scope) {    $scope.base64 = angular.injector(['main']).get('base64');};

Do this:

var algoController = function($scope, $injector) {    $scope.base64 = $injector.get('base64');};

But most of the time you should inject your service directly, rather than dynamically, like so:

var algoController = function($scope, base64) {    $scope.base64 = base64;};
