Передача переменной в представление

Question

Я написала представление шапки сайта:

 <div class="bg-light">
        <nav class="navbar navbar-expand-lg  navbar-dark bg-mgray">
    <div class="container">
        <a class="navbar-brand" href="{{ route("home") }}">{{ config('app.name') }}</a>

        <input type="checkbox" id="navbar-toggle-cbox">


        <label class="navbar-toggler" for="navbar-toggle-cbox" data-toggle="collapse"
               data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false"
           aria-label="Toggle navigation">
            <span class="navbar-toggler-icon"></span>
        </label>

          <div class="collapse navbar-collapse" id="navbarSupportedContent">

         <ul class="navbar-nav mr-auto">

В этом представлении я пытаюсь инклудить представление категорий. Как только я это делаю - у сайта работает главная страница и я могу зайти в любую категорию. Все прекрасно. Но как только я пытаюсь посетить какие либо другие страницы - я получаю ошибку:

Undefined variable: categories (View: ###/resources/views/includes/categories.blade.php)

Я могу заинклудить список категорий хоть посреди домашней страницы и весь сайт прекрасно работает, но как только я пытаюсь сделать это в панели навигации - все перестает работать.

Я совсем запуталась в какое представление и каким образом я должна передать переменную $categories. И вообще потеряла логическую цепочку связи подключения представления и того, что переменная перестает передаваться.

Привожу код web.php и indexcontroller.php:

<?php

/*

|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!

    include 'auth.php';

Route::prefix('admin') -> group(function (){
    Route::middleware(['admin_panel_access'])->group(function () {

    });

Route::middleware(['auth'])->group(function () {
    Route::get('banned', 'ProfileController@banned')->name('profile.banned');

Проблема решена. Файл app/providers/AppService/Provider.php должен выглядеть так

<?php

namespace App\Providers;

use Illuminate\Support\Facades\View;
use Illuminate\Support\ServiceProvider;

class AppServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap any application services.
     *
     * @return void
     */
    public function boot()
    {
        View::share('categories', (new \App\Category)->roots());

    }

    /**
     * Register any application services.
     *
     * @return void
     */
    public function register()
    {
        if ($this->app->environment() !== 'production') {
            $this->app->register(\Barryvdh\LaravelIdeHelper\IdeHelperServiceProvider::class);
        }
    }
}
