Make data from AppServiceProvider available to controllers

[graceful oxide]

What kind of data are you thinking of sharing?

An URL parameter

Actually some flag, depending of the value on that parameter

Why don't you just use the request() helper or inject $request into your controller? If you have complex logic you can add a macro to the request class

Sounds more like a use case for middleware.

I'm trying

Route::group(['middleware' => 'store_middleware'], function () {
    Route::get('/tienda/{store_slug}', [HomeController::class, 'Home']);
});

Then in the middleware within the handle() method the parameter is always null

    public function handle(Request $request, Closure $next): Response
    {
        $slug = $request->get('store_slug');
    }
