Class 'Illuminate\Support\Facades\Input' not found

In config/app.php, replace:

'Input' => Illuminate\Support\Facades\Input::class

with

'Input' => Illuminate\Support\Facades\Request::class,

if you're using less version of Laravel 5.2

In config/app.php, replace:

'Input' => Illuminate\Support\Facades\Input::class,

Or You can import Input facade directly as required,

use Illuminate\Support\Facades\Input;

In Laravel 5.2 Input:: is replaced with Request::

use

Request::

Add to the top of Controller or any other Class

use Illuminate\Http\Request;

In your case

$image_tmp = $request->image;
$fileName = time() . '.'.$image_tmp->clientExtension();

Laravel 6X The Input facade, which was primarily a duplicate of the Request facade, has been removed. If you are using the Input::get method, you should now call the Request::input method. All other calls to the Input facade may simply be updated to use the Request facade.

You can directly use $request as well

$request->all();
