@ngdoc error
@name $injector:strictdi
@fullName Explicit annotation required
@description

This error occurs when attempting to invoke a function or provider which
has not been explicitly annotated, while the application is running with
strict-di mode enabled.

For example:

```
angular.module("myApp", [])
  // BadController cannot be invoked, because
  // the dependencies to be injected are not
  // explicitly listed.
  .controller("BadController", function($scope, $http, $filter) {
    // ...
  });
```

To fix the error, explicitly annotate the function using either the inline
bracket notation, or with the $inject property:

```
function GoodController1($scope, $http, $filter) {
  // ...
}
GoodController1.$inject = ["$scope", "$http", "$filter"];

angular.module("myApp", [])
  // GoodController1 can be invoked because it
  // had an $inject property, which is an array
  // containing the dependency names to be
  // injected.
  .controller("GoodController1", GoodController1)

  // GoodController2 can also be invoked, because
  // the dependencies to inject are listed, in
  // order, in the array, with the function to be
  // invoked trailing on the end.
  .controller("GoodController2", [
    "$scope",
    "$http",
    "$filter",
    function($scope, $http, $filter) {
      // ...
    }
  ]);

```
