This have problems https://socialiteproviders.com/Line/

composer require socialiteproviders/line

2. create app/Providers/LineProvider.php

https://github.com/SocialiteProviders/Line/blob/master/Provider.php

namespace App\Providers;

use GuzzleHttp\RequestOptions;
use Laravel\Socialite\Two\InvalidStateException;
use \SocialiteProviders\Manager\OAuth2\AbstractProvider;
use \SocialiteProviders\Manager\OAuth2\User;

class LineProvider extends AbstractProvider
{
    public const IDENTIFIER = 'LINE';

    /**
     * The separating character for the requested scopes.
     *
     * @var string
     */
    protected $scopeSeparator = ' ';

    /**
     * The scopes being requested.
     *
     * @var array
     */
    protected $scopes = [
        'openid',
        'profile',
        'email',
    ];

    /**
     * Get the authentication URL for the provider.
     *
     * @param  string  $state
     * @return string
     */
    protected function getAuthUrl($state)
    {
        return $this->buildAuthUrlFromBase(
            'https://access.line.me/oauth2/v2.1/authorize',
            $state
        );
    }

    /**
     * Get the token URL for the provider.
     *
     * @return string
     */
    protected function getTokenUrl()

            [
                RequestOptions::HEADERS => [
                    'Authorization' => 'Bearer '.$token,
                ],
            ]
        );

        return json_decode((string) $response->getBody(), true);
    }

    /**
     * Map the raw user array to a Socialite User instance.
     *
     * @param  array  $user
     * @return \Laravel\Socialite\User
     */
    protected function mapUserToObject(array $user)
    {
        return (new User())->setRaw($user)->map([

        ]);
    }

    // /**

    public function user()
    {

            ->setRefreshToken($this->parseRefreshToken($response))
            ->setExpiresIn($this->parseExpiresIn($response));
    }
}

3. edit app/Providers/AppServiceProvider.php

namespace App\Providers;

use Illuminate\Support\ServiceProvider;

class AppServiceProvider extends ServiceProvider
{
    /**
     * Register any application services.
     */
    public function register(): void
    {
        //
    }

    /**
     * Bootstrap any application services.
     */
    public function boot(): void
    {
        $this->bootLineSocialite();
    }

    public function bootLineSocialite(): void
    {
        // // laravel Socialite 和 Socialite Line 有問題，就是 在初始載入不了
        // // 看Socialite Line 作者還有在3星期前維謢，所以就不知道怎麼回事
        // // https://medium.com/laravel-news/adding-auth-providers-to-laravel-socialite-ca0335929e42
        $socialite = $this->app->make('Laravel\Socialite\Contracts\Factory');

        $socialite->extend(
            'line',
            function ($app) use ($socialite) {
                $config = config('services.line');

                // https://github.com/SocialiteProviders/Line/blob/master/Provider.php
                return $socialite->buildProvider(LineProvider::class, $config); // \SocialiteProviders\Line\Provider::class
            }
        );
    }
}

4. routes/web.php

Route::get('/auth/redirect', function () {
    return Socialite::driver('line')->redirect();
});

Route::get('/auth/callback', function () {
    $user = Socialite::driver('line')->user();

    dd($user);
});
