Laravel Socialite - handleProviderCallback() method not showing stored session - php

Question

I am trying to integrate Socialite in my Laravel project. I am trying to store a session in buyerSignup.blade.php file and then trying to get that session value in Socialite's handleProviderCallback() method. But it is not showing any value don't know why. Although the other method
redirectToProvider() showing the session value.
I need that session value in handleProviderCallback() method to process it and take actions based upon the value of session. Below is a actual of code that I am using.
Storing a session value in buyerSignup.blade.php
#php
\Session::put('buyerSignupFb','true');
#endphp
Trying to get the above stored value in LoginController's handleProviderCallback() method.
<?php
namespace App\Http\Controllers\Auth;
use App\Http\Controllers\Controller;
use Illuminate\Foundation\Auth\AuthenticatesUsers;
use Illuminate\Http\Request;
use Auth;
use App\sellerData;
use App\buyerData;
use App\sellerDealCat;
use App\subCatData;
use App\Session;
use App\User;
use Illuminate\Support\Facades\Hash;
use Illuminate\Support\Facades\DB;
use Socialite;
class LoginController extends Controller
{
use AuthenticatesUsers;
protected $redirectTo = '/home';
public function __construct()
{
$this->middleware('guest')->except('logout');
$this->middleware('guest:seller')->except('logout');
$this->middleware('guest:buyer')->except('logout');
}
public function redirectToProvider()
{
return Socialite::driver('facebook')->redirect();
}
public function handleProviderCallback()
{
//cant get the value of the session defined in buyerSignup.blade.php
// echo doesn't work too
return \Session()->get('buyerSignupFb');
}
}
Any suggestion what I am doing wrong or how to make it work. TIA

U doing all good, but not enought, first u set a redirect provider
public function redirectToProvider()
{
return Socialite::driver('facebook')->stateless()->redirect();
}
it's good, when user will give access to his token, u need to handle callback in handleProviderCallback(), where u need to exchange user auth code to acces token. All of this socialite makes automatically, all what u need its just call it
public function handleProviderCallback()
{
$externalUser = Socialite::driver('facebook')->stateless()->user();
\\check if user exists, if not create
$auth->login($user, true);
if ($user->type = 'seller'){$this->redirectTo = '/forSellers'} else {$this->redirectTo = '/forOtherGroup'}
return redirect($this->redirectPath());
}
