How to change url prefix when changing language in laravel?

Question

Laravel

I have a controller that changes the language.

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\App;
use mysql_xdevapi\Session;

class languagesController extends Controller
{
    public function changeLocale($locale) {
        session(['locale'=>$locale]);

        App::setLocale('$locale');

        return redirect()->back();
    }
}

There are only two languages, so I just pass data in the link to change the language:

<a class="language-btn__link" href="{{ route('locale', __('main.change_lang_link')) }}">

Here is my route:

<?php

use Illuminate\Support\Facades\App;
use Illuminate\Support\Facades\Route;

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

Route::get('/', function () { return view('home');})->name('index');
Route::get('/home', function () {return view('home');})->name('home');

Here is the facade:

<?php

namespace App\Http\Middleware;

class LanguageSwitcher
{
    public function handle($request, \Closure $next)
    {
       \App::setlocale(session ('locale'));

        return $next($request);
    }
}

Now the translation is working, but I would like to add a prefix to the url so that it would turn out /home/ru or /ru

Question, how to do this? And along the way, the question is how to determine to load immediately the default prefix when the page is first loaded?

I tried setting a variable in the route:

Route::get('/{lang}/home', function (Lang $lang) {return view('home');})->name('home');

And in the link write like this

href="{{ route('index', ['lang' => __('main.change_lang_link')]) }}"

But it doesn't work. How to do it right?

Take the ready package mcamara/laravel-localization
Well, or peep how it is implemented there.
