socialite with laravel. [Login with => Facebook, Google, Twitter] e.t.c social site.

First We should install Laravel Socialite:

composer require laravel/socialite

Configuration: 

After installing the Socialite library, register the Laravel\Socialite\SocialiteServiceProvider in your config/app.phpconfiguration file:

'providers' => [
    // Other service providers...

    Laravel\Socialite\SocialiteServiceProvider::class,
],

Also, add the Socialite facade to the aliases array in your app configuration file:

'Socialite' => Laravel\Socialite\Facades\Socialite::class,

Configuration Part-2: 

Before using Socialite, you will also need to add credentials for the OAuth services your application utilizes. These credentials should be placed in your config/services.phpconfiguration file, and should use the key facebook, twitter, linkedin, google, github or bitbucket, depending on the providers your application requires. For example:

'github' => [
    'client_id' => env('GITHUB_CLIENT_ID'),         // Your GitHub Client ID
    'client_secret' => env('GITHUB_CLIENT_SECRET'), // Your GitHub Client Secret
    'redirect' => 'http://your-callback-url',
],

Now Follow the Main Documents:

Make  2 routes:

1. Route::get('login/{service}', 'Auth\LoginController@redirectToProvider_all');

2. for => handle Provider Callback:

Copy  3 methods from below and paste in LoginController.php:

/**it works for all socials: facebook, twitter,google **/
/**
 * Redirect the user to the Google/e.t.c authentication page.
 *
 * @return \Illuminate\Http\Response
 */
public function redirectToProvider_all($service){
    //$this->check = $loginid;
    return Socialite::driver($service)->redirect();
}

/**
 * Obtain the user information from Google/e.t.c.
 *
 * @return \Illuminate\Http\Response
 */

public function handleProviderCallback_all($service){

    $user = Socialite::driver($service)->stateless()->user();
    $access_token = $user->token;
    $name = $user->name;
    $email = $user->email;
    $pass = $user->id;
    if($this->isRegistered($email)){

        $user_array = array();
        $user_array['email'] = $email;
        $user_array['password'] = $pass;

        /*For Login */
        if(Auth::attempt($user_array)){
            return Redirect::to('/home');
        }else{
            echo "pass incorrect";
        }
    }else{
        return User::create([
            'name' => $name,
            'email' => $email,
            'password' => Hash::make($pass),
        ]);
    }
}
public function isRegistered($mail){

    $user = User::where('email', $mail)->first();
    if ($user) {
        return true;
    } else {
        return false;
    }
}
