Import the Correct Auth Facade

In DashboardController.php file, replace this incorrect import:

use Illuminate\Container\Attributes\Auth;

with the correct one:

use Illuminate\Support\Facades\Auth;

Then your index() function should be work.

Why did this happen?

• You mistakenly imported Illuminate\Container\Attributes\Auth, which is not the correct Auth facade.

• Blade templates (dashboard.blade.php) recognise Auth::user()
  because Blade automatically provides access to facades.

• However, Controller need the correct namespace
  Illuminate\Support\Facades\Auth.
