Share variables to each view in laravel doesn't seems to work

I'm trying to share the result from query to all views but it doesn't seems to work.

I have in my Category model this

public function getAllImageCategories()
{
    $categoires = Category::all();
    return $categoires;
}

Then in my HomeController __constructor this

public function __construct()
{
    $Category = new Category;
    $allCategories = $Category->getAllImageCategories();

    View::share('allCategories', $allCategories);
    $this->middleware('auth');
}

And in the view

@foreach($allCategories as $category)
  <li><a href="#"><i class="fa fa-btn fa-sign-out"></i>{!! $category->name !!}</a></li>
@endforeach

The error

Undefined variable: allCategories

Why is this error? What I mistaken here?

I suggest you to use the View Composer for all view pages.

https://laravel.com/docs/5.4/views#view-composers

Otherwise you can use Sharing Data With All Views on the same page go to

your/project/directroy/app/Providers/AppServiceProvider.php

and add your code into boot method 

public function boot()
{
    $Category = new Category;
    $allCategories = $Category->getAllImageCategories();
    View::share('allCategories', $allCategories);
}

You should put the code into the boot() method of service provider:

public function boot()
{
    $Category = new Category;
    $allCategories = $Category->getAllImageCategories();
    View::share('allCategories', $allCategories);
}

You should place calls to share within a service provider's boot method. You are free to add them to the AppServiceProvider or generate a separate service provider to house them.
