Provider Class not found in In ProviderRepository.php line 208

I have create a simple Laravel Package and pushed it on Github

https://github.com/akshaykhale1992/model-notes

and Published the Package on Packagist

https://packagist.org/packages/akshaykhale1992/model-note

I tried to install it in my laravel application, it pulled the package from Github but the package installation was not successful.

Below is the Error that is returned by composer command

root@root.com:~/$ composer require akshaykhale1992/model-note
