How to pass a variable to the master template?

Question

Laravel

I can’t find an answer anywhere, how to pass a variable to the mater template, I have a shopping cart, I make a variable to display products, on the product page, I display this variable, since the controller calls the model and searches for a variable, but how to pass this variable in the master template and so that all this is displayed on any page, and does not give an error about a variable not found? I try through AppServiceProvider.php

<?php

namespace App\Providers;

use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Facades\View;
use App\Models\Order;

class AppServiceProvider extends ServiceProvider
{
    public function boot()
    {   
        $orderId = session('orderId');
        $order = Order::find($orderId);   
        View::share('order', $order);
    }
}

p.s. if you pass just a string, then everything is good, but otherwise null.
