Laravel 5.1 - Session and request both do not hold values

After using Laravel's Auth method I find that I am not able to get email in its session. Nor I am able to retrieve anything in the request object.

dd(Session::all()) returns below

array:5 [▼ "_token" => "xxTG9QCKEc6YIGfT9JWTafSjacJhph7QjyIDJU6v" "_previous" => array:1 [▶] "flash" => array:2 [▶] "email" => null "login_82e5d2c56bdd0811318f0cf078b78bfc" => 1 ]

And Log::info('In Welcome Controller - email id - ' .$request->email .' - '. $request->username . ' - ' . Session::get('email'));

Returns blank except Session::get('email') return null

This is the Welcome Controller which is displayed on Authentication.

''' class WelcomeController extends Controller {

/**
 * Display Welcome and the list of entries by user or ask him to create one.
 *
 * @return \Illuminate\Http\Response
 */
public function displayWelcome(Request $request)
{
        Log::info('In Welcome Controller - email id - ' .$request->email .' - '. $request->username . ' - ' . Session::get('email'));
    
        
        Log::info('In Welcome Controller - all in session - '. dd(Session::all()) );
        $email = $request->email;
        Session::put('email', $request->email);  // # User that is currently logged in
        Session::save();
    return view('pages.Welcome')->with("email",$email);
}

} '''

Routes php ''' Route::get('Welcome', ['as' => 'login','uses' =>'WelcomeController@displayWelcome']);

// Authentication routes... Route::get('auth/login', ['as' => 'auth/login','uses' =>'Auth\AuthController@getLogin']); Route::post('auth/login', ['as' => 'auth/login','uses' =>'Auth\AuthController@postLogin']); Route::get('auth/logout', ['as' => 'auth/logout','uses' =>'Auth\AuthController@getLogout']);
