Laravel 5.1 view composer initiates before middleware - php

Question

I am developing a simple web application with Laravel 5.1 and my development environment is Homestead.
I have a view composer to pass Auth::user() data to admin panel related views automatically. Most general admin panel pages (Dashboard, Settings etc.) uses AdminController, and it extends Laravel's Controller. Specific admin panel pages (Users, Orders etc.) has their own controllers (Admin\UsersController, Admin\OrdersController respectively), which are extends AdminController.
No any middleware registered in routes for admin panel related routes, instead AdminController loads the auth middleware (which checks if registered user tries to load the page). And no other controller that extends AdminController overrides the constructor.
My problem is that if user is not logged in and tries to load an admin panel page (doesn't matter which one; Dashboard, Settings, Users, Orders - because the view composer called for every single one to pass Auth::user() data) there is no warning says "You are not authorized." or no redirection to login page, just an exception thrown which says Auth::user() is null.
Doesn't the auth middleware called first? If not what should I do to prevent the exception to be thrown (returning from view composer is not an elegant solution for my point of view by the way)?
Thanks in advance.
Addendum
AdminController
<?php
namespace App\Http\Controllers\Admin;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;
class AdminController extends Controller
{
public function __construct()
{
// After middlewares
$this->middleware("auth");
$this->middleware("admin");
// Before middlewares
$this->middleware("no-cache");
}
/**
* Display a listing of the resource.
*
* #return Response
*/
public function index()
{
return view("admin.index");
}
}
Admin\OrdersController
<?php
namespace App\Http\Controllers\Admin;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use App\Order;
class OrdersController extends Controller
{
/**
* Display a listing of the resource.
*
* #return Response
*/
public function index()
{
$orders = Order::with("address")->get();
return view("admin.orders.index")->with("orders", $orders);
}
}
ComposerServiceProvider
<?php
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
use Auth;
class ComposerServiceProvider extends ServiceProvider
{
/**
* Bootstrap the application services.
*
* #return void
*/
public function boot()
{
view()->composer("layouts.admin.default", function ($view) {
$admin = Auth::user();
$view->with([
"admin" => $admin,
"picture" => $admin->pictures[0]
]);
});
}
/**
* Register the application services.
*
* #return void
*/
public function register()
{
//
}
}
Note: ComposerServiceProvider is registered in config/app.php.

Your Admin\OrdersController extends App\Http\Controllers\Controller, when it should extend App\Http\Controllers\Admin\AdminController. That's why you are not getting a redirection.
