How to use a dynamic variable in Laravel group routes?

Question

eg:

 Route::group(['prefix' => '{lang?}'], function () {
 //..
 });

create a variable in middleware:

public function handle($request, Closure $next){

$lang = session('locale');

App::setLocale($lang);

return $next($request);      
});

also tried to get data in prefix but got null

Route::group(['prefix' =>  config('app.locale')], function () {
//..
});

or

Route::group(['prefix' =>  session('locale')], function () {
//..
});

change language on a separate route through the session

Route::get('setlocale/{locale}', function ($locale) {

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

return redirect()->back();

})->name('setlocale');

Thank you in advance for your help.

You do not need to group routes by route lang, you can create your own middleware and group your routes under this middleware and use this code inside it:

public function handle($request, Closure $next){
     $lang = request->get('locale');
     $currentLang = App::getLocale();

     //If locale exists in the url and it changed
     if($lang && $lang != $currentLang) App::setLocale($lang);

     //If locale doesn't exist in the url, fallback to default locale
     if(!$lang) App::setLocale('en');

     return $next($request);      
 });

URL should be data/store?locale=en, ur url should always add localeafter ?in url, otherwise your localedefault will be used

EDIT: locale URL-, , , , : Laravel localization mcmara
