Multilingual Laravel 8 depending on the user's GEO?

Question

Laravel

Hello. The question is of interest - how to set multilingualism for your site, depending on the user's preferred language?

I have already implemented the switch - and the basic translation for the test. The base value is always indicated by en - and I understand the app config I can change - but this is not the case, since there is a base language and a language that will be replaced. I need the user's language to be checked through the middleware and set as a priority!

SetLocale - Middleware

public function handle(Request $request, Closure $next)
    {
        $locale = session('locale');

        $defaultLocale = App::getLocale(); - вот тут я думаю ошибка где то, ну или вы мне подскажите :((

        App::setLocale($locale ?? $defaultLocale);

        return $next($request);
    }

web.php

Route::get('locale/{locale}', 'Site\[email protected]')->name('locale');

Route::group(['namespace' => 'Site', 'middleware' => 'set locale'], function() {
        // Base websites Urls
        Route::get('/', '[email protected]')->name('home');
       .......
      .......
    });

        'auth' => \App\Http\Middleware\Authenticate::class,
        'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,

        session(['locale' => $locale]);

I did it according to oak - but if someone offers a better one - I will not refuse!
SetLocale.php (Middleware)

public function handle(Request $request, Closure $next)
    {
        $locale = session('locale');

        $defaultLocale = substr($_SERVER['HTTP_ACCEPT_LANGUAGE'], 0, 2);


        App::setLocale($locale ? $defaultLocale : $defaultLocale);

        return $next($request);
    }
