Undefined property: App\Controllers\Home::$input

Hello there,
I am encountering this error and I have no clue why! 

Code:

ErrorException
Undefined property: App\Controllers\Home::$input

PHP Code:

<?php namespace App\Controllers;

class Home extends BaseController
{

    public function index()
    {
        $validation =  \Config\Services::validation();
        $view['partner'] = NULL;

        $partners = array('test','test2');
        $partner = $this->input->get('partner');

        if(in_array($partner, $partners))
            $view['partner'] = $partner;

        return view('home', $view);
    }

    //--------------------------------------------------------------------

} 


I'd appreciate it if someone could assist me.
