new laravel package not recognized

I was writing my first laravel package, so I could use it and understand how packages work and learn how to write packages and etc.
But my project didn’t recognize the package that I wrote.
Here is my package Github link: https://github.com/IIIphr/Shamsi_Calendar
And this is my main project: https://github.com/IIIphr/aimeos_shamsi
I use this command to add my package to the app: composer require iiiphr/shamsi_calendar
And it’ll be added successfully (at least I guess). Then in the temp Controller, I wrote this:

<?php

namespace AppHttpControllers;

use IlluminateHttpRequest;
use iiiphrshamsi_calendar;

class temp extends Controller
{
    public function index(){
        return shamsi_calendar::get_date();
    }
}

And a route:
Route::get('/date','temp@index');
But in the http://localhost:8000/date, I will face this error:

Before, I have tried other ways and the result was anything but success.
Another thing, I have this error in visual studio code in the temp controller:
Undefined type 'iiiphrshamsi_calendar'.intelephense(1009)
I will appreciate any kind of help 🙂

Answer

You import the library perfectly but you don’t use the Calendar Controller that the package gives you. The package haves a controller called CalendarController, you have two ways, extends from this controller or create an instance of this controller, if you extend the controller from this:

<?php

namespace AppHttpControllers;

use iiiphrshamsi_calendarCalendarController;

class temp extends CalendarController
{
    public function index(){
        return $this->get_date();
    }
}

What do you think about it?
