Laravel Route to controller in subfolder getting errors

Question

I've found many posts regarding putting controllers in sub folders, Most if not all seem to be related to namespace or naming issues. I just cant seem to get it working, and keep getting the following ReflectionException and FatalError Reporting the class is in use.

I have tried using different class names, that didn't solve anything. As long as I route to a controller in the Admin folder/namespace I get the listed error. I have ran composer dump-autoload after every change and ran php artisan cache:clear just to be safe

My Folder Structure

/app/
    Console/
    Exceptions/
    Http/
        Controllers/
            Admin/
                DashboardController.php

            Controller.php
            ...OtherController.php files live here in the base Controller folder
        Middleware/
    Providers/

/routes/web.php

...
// Admin Routes
Route::group( [ 'namespace' => 'Admin','prefix' => 'admin' ], function(){

    Route::get( '/', 'DashboardController@showAdminHome' )->name( 'admin.dashboard' ); 

});

/app/Http/Controllers/Admin/DashboardController.php

<?php

namespace App\Http\Controller\Admin;

use App\Http\Controllers\Controller;

class DashboardController extends Controller {

    public function showAdminHome() {
        return view( 'admin.dashboard' );
    }

} //- END Admin\DashboardController{}

I've ran out of things to try and appreciate any help.

Answer 1

Check your namespace also add full path in namespace.

namespace App\Http\Controllers\Admin;

Answer 2

You need to use correct namespace to fix the error:

namespace App\Http\Controllers\Admin;
