Laravel 5 Facades or Dependency Injection Pros and Cons

Question

I am developing a package for Laravel 5, I decided to benefit form Dependency Injection in my package and it is easy to implement in Laravel particularly for constructor injection, but when it comes to Facades some new issues arise. when we have classes like

  class MyController extends \App\Http\Controllers\Controller
 {        
   public $text;
   protected $lang; 

   public function __construct(\Lang $lang)
   {         
      $this->lang = $lang;
   }

   public function myFunction(){
     $this->text = $this->lang->get('package::all.text1');           
   }
  }

The code above doesn't work since the Lang is a Facade, therefore we have to change the code to this:

  use Illuminate\Translation\Translator

  class MyController extends \App\Http\Controllers\Controller
 {        
   public $text;
   protected $translator; 

   public function __construct(Translator $translator)
   {         
      $this->translator = $translator;
   }

   public function myFunction(){
     $this->text = $this->translator->get('package::all.text1');           
   }
  }

The Question: I need to know what are the advantages and disadvantage of using the facades against using the constructor injection

I also have checked this question: laravel - dependency injection and the IoC Container and laready asked this question: Dependency Injection in Laravel 5 Package To Use or Not To Use

you just can help as well with confirming the answer of the first question as well
