Laravel one click sorting

I'm new on this Laravel and was trying to play around the Laravel's quickstart project. I'm not familiar with the variable set within the template. I'm trying to create a one button/link to sort by ascending or decending all the retrieved records.

Usually I have no problem with basic PHP sorting by using switch (), but since I'm using Laravel, things are getting a little bit unfamiliar to me. So here's the code:-

routes.php

Route::group(['middleware' => ['web']], function () {

Route::get('/sort/{id}', function ($id)  { // get the main page ("/") 
    switch ($id) {
            case 'asc' :
                return view('tasks', [ // get the tasks table from the database
                'tasks' => Task::orderBy('name', 'asc')->get(),
                'sort' => "desc"
                // From the tasks table, get the listing from the table and arrange them ascending by date of creation 
            ]);
            case 'desc' :
                return view('tasks', [ // get the tasks table from the database
                'tasks' => Task::orderBy('name', 'asc')->get(), // From the tasks table, get the listing from the table and arrange them ascending by date of creation 
                'sort' => "asc"
            ]);
        }
    });

tasks.blade.php

<div class="panel-body">
                        <table class="table table-striped task-table">
                            <thead>
                                <th><a href="/sort/">Task</a></th>
                                <th>&nbsp;</th>
                            </thead>
                            <tbody>
                                @foreach ($tasks as $task) <!-- display the listings from the tasks table -->
                                    <tr>
                                        <td class="table-text"><div></div></td>
                                        <td class="table-text"><div></div></td>

                                        <!-- Task Delete Button -->
                                        <td>
                                            <form action="" method="POST"> <!-- form action select the id on the task table database($task->id) -->
                                                
                                                 <!-- delete the field -->

                                                <button type="submit" class="btn btn-danger">
                                                    <i class="fa fa-btn fa-trash"></i>Delete
                                                </button>
                                            </form>
                                        </td>
                                    </tr>
                                @endforeach
                            </tbody>
                        </table>
                    </div>

I just refer some of the codes on the internet and make some of my own as I'm not used with the variable within the HTML part in Laravel. I thought it would work but when I run the code, it throws the undefined variable: sort in the tasks.blade.php. Usually any variable is within the backend PHP, but this is a whole new environment to me. So, I wonder how does variable in HTML works? and how to make the sort working?
