Laravel 5 redirect with error not working in Handler.php

I want to redirect to a page with error message from Handler.php. It will redirecting successfully but without showing the error messaging in the intended page.

Below is my code in handler.php file:

public function render($request, Exception $exception)
{
if ($exception instanceof \Illuminate\Http\Exceptions\PostTooLargeException)
            return \Redirect::to('administrator/media')->with('errorMessage', 'File size is too big.');

// bla bla bla
}
