Laravel 5.5以降？のbreadcrumbsのdetailの書き方

// [ルート]

// routes\breadcrumbs.php
Breadcrumbs::for('users.show', function ($trail, $user) {
    $trail->parent('users.index');
    $trail->push('ユーザー詳細', route('users.show', $user->id));
});

// routes\web.php
Route::get('users/{user}', 'UserController@show')->name('users.show');


// [コントローラー]

// app\Http\Controllers\UserController.php
use App\User;
...
    public function show(User $user)
    {
    	        return view('users.show', ['user' => $user]);
    }


// [ビュー]

// resources\views\users\show.blade.php
@component('layouts.user')
<div class="breadcrumb">
    {{ Breadcrumbs::render('users.show', $user) }}
</div>
