Laravel Language changer

I add localization to my laravel app. I define language in my routes.

Route::group(['prefix' => '{language}/tender', 'middleware' => ['permission:tender-page']], function () {
    Route::get('/', 'TenderController@index')->name('tender');
    Route::get('/add', 'TenderController@add')->name('tender_add');
    Route::get('/{id}', 'TenderController@detail')->name('tender_detail');
});

I try to change languages by this way

<li class="nav-item">
    <a href="" class="nav-link">RU</a>
</li>
<li class="nav-item">
    <a href="" class="nav-link">TR</a>
</li>

but if i use this way, this kind of routes Route::get('/{id}', 'TenderController@detail')->name('tender_detail'); got error.

How can realize language changer?
