Syntax error unexpected end of file laravel

I have an interesting situation to which I can’t figure out why it is happening. I am getting the error stated in the title. This is happening on a Blade component. I have a Blade component that accepts some values and creates Label and Input Checkbox HTML elements with those values. Now, I want to specify whether the checkbox should be «checked» or not, to which I have {{ $attributes }} on the component for that. Ternary or simple if statements both yield the same results.

input-checkbox.blade.php (the component)

@props([
'for' => 'undefined_for',
'name' => 'undefined_name',
'value' => 'undefined_value',
'aria_label' => 'undefined_aria_label'
])

<label for="{{ $for }}" class="form-label">
{{ $slot }}
</label>
<input type="checkbox"
class="form-check-input me-1"
name="{{ $name }}"
id="{{ $for }}"
value="{{ $value }}"
aria-label="{{ $aria_label }}"
{{ $attributes }}>

edit.blade.php (where component is used — note, this is all the code there is in this file)

<x-input-checkbox
name="roles[]"
for="role_{{ $role->role }}"
value="{{ $role->role }}"
aria_label="Role {{ $role->role }}"
{{ $role->checked ? 'checked' : '' }}> // <<< this is the line that causes problem
Role Label Text
</x-input-checkbox>

OR

<x-input-checkbox
name="roles[]"
for="role_{{ $role->role }}"
value="{{ $role->role }}"
aria_label="Role {{ $role->role }}"
@if($role->checked)checked@endif> // <<< this too fails
Role Label Text
</x-input-checkbox>

OR

<x-input-checkbox
name="roles[]"
for="role_{{ $role->role }}"
value="{{ $role->role }}"
aria_label="Role {{ $role->role }}"
@if($role->checked){{ 'checked' }}@endif> // <<< this too fails
Role Label Text
</x-input-checkbox>

But this does work, plain HTML.

<label for="role_{{ $role->role }}" class="form-label">
Role Label Text
</label>
<input type="checkbox"
class="form-check-input me-1"
name="roles[]"
id="role_{{ $role->role }}"
value="{{ $role->role }}"
aria-label="Role {{ $role->role }}"
{{ $role->checked ? 'checked' : '' }}> // <<< this works, the box is marked checked if true

Any assistance is greatly appreciated. Thanks.

I use Laravel’s Socialite.

I tried to implement login using Github authentication and wrote the following code.

<? php
namespace App  Http  Controllers  Auth;
use App  Http  Controllers  Controller;
use Illuminate  Foundation  Auth  AuthenticatesUsers;
use Socialite;// Added!
use Illuminate  Http  Request;// Added!
use Illuminate  Support  Facades  DB;
class LoginController extends Controller
{
    / *
    | ------------------------------------------------- -------------------------
    | Login Controller
    | ------------------------------------------------- -------------------------
    |
    | This controller handles authenticating users for the application and
    | redirecting them to your home screen. The controller uses a trait
    to conveniently provide its functionality to your applications.
    |
    * /
    use AuthenticatesUsers;
    / **
     * Where to redirect users after login.
     *
     * @var string
     * /
    protected $redirectTo = '/ home';
    / **
     * Create a new controller instance.
     *
     * @return void
     * /
    public function __construct ()
    {
        $this->middleware ('guest')->except ('logout');
    }
    / **
     * Redirect users to GitHub authentication page
     *
     * @return  Illuminate  Http  Response
     * /
    public function redirectToProvider () // Added!
    {
        return Socialite :: driver ('github')->scopes (['read: user', 'public_repo'])->redirect ();
    }
    / **
     * Get user information from GitHub
     *
     * @return  Illuminate  Http  Response
     * /
    public function handleProviderCallback (Request $request)
    {
        $github_user = Socialite :: driver ('github')->user ();
        $now = date ("Y/m/d H: i: s");
        $app_user = DB :: select ('select * from public.user where github_id =?', [$github_user->user ['login']]);
        if (empty ($app_user)) {
            DB :: insert ('insert into public.user (github_id, created_at, updated_at) values ​​(?,?,?)', [$Github_user->user ['login'], $now, $now]);
        }
        $request->session ()->put ('github_token', $github_user->token);
        return redirect ('github');
    }

The following error will be displayed.

Symfony  Component  Debug  Exception  FatalThrowableError (E_PARSE)
syntax error, unexpected end of file, expecting function (T_FUNCTION) or const (T_CONST)

I understand that something unexpected is written at the end of the file, but

(T_FUNCTION) or const (T_CONST)

What is that is clogged because it does not come out even if you google.

If i know the solution to the error, please let me know. Thank you in advance.
