Fixing Laravel 10 return type error in Controller

Laravel 10 added support for types and it’s great. In some cases, you might see errors if the defined types and actual return types do not match.

When you create a new Controller using php artisan make:controller IndexController , you get this default stub.

<?php
 
namespace AppHttpControllers;
 
use IlluminateHttpRedirectResponse;
use IlluminateHttpRequest;
use IlluminateHttpResponse;
 
class IndexController extends Controller
{
    /**
     * Display a listing of the resource.
     */
    public function index(): Response
    {
        //
    }
 
    /**
     * Display the specified resource.
     */
    public function show(): Response
    {
        //
    }
 
    // ...
 
}

 In this case, if you try to return a view inside of either index or show methods using the view helper, you will see an error.

TypeError:

Return value is expected to be IlluminateHttpResponse, IlluminateViewView returned

The fix is to update the return type of the method from Response to View from the IlluminateViewView namespace.

use IlluminateViewView;
public function index(): View
    {
        //
    }
    

Alternatively, you could also use response()->view(...), Response::view  or update the default return type to Response | View
