php - Is it possible to intiailize variables in a constructor for a Laravel facade?

If I am creating a custom facade and want to have certain variables initialized at every instance of using customFacade::doSomething(), is that possible? My main purpose for doing this is to be able to store variables that are other objects and call functions on them directly. Example being customFacade::client->send() where in this case client is the initialized variable of an object with a send() function. I am aware I can have a function client() instead and return the a new instance of the object so the send() goes through, but I'd still like to know if its possible the other way.

In a normal class I can do below, but it doesn't work on facades.

$protected client;

public function __construct()
{
    $this->client = new instanceOfObject();
}

Solution:

Since a Facade uses static functions you could only do something like

public static $client = null;

public static function init() {
    if(self::$client == null)
        self::$client = new instanceOfObject();
}

// somewhere else
customFacade::init();
customFacade::client->send();

Solution:

Laravel will resolve all the dependencies you need out of the service container, in the class constructor which underlies your facade. A toy example to show my point, will have UserRepository resolved in the DateService, and therefore the Dates facade.

Usage like,

    return view('profile' => [
        ...
        'time' => Dates::loggedLocal(),
        ...
    ]);

DatetimeService.php

class DatetimeService
{
    private $userRepository;
    
    public function __construct(
        UserRepository $userRepository
    ) {
        $this->userRepository = $userRepository;
    }

    /**
     * Get the logged in users local time
     *
     * @return Carbon
     */
    public function loggedLocal() : Carbon
    {
        $user = $this->userRepository->current();
        return Carbon::now()->setTimezone($user->timezone);
    }

Dates.php

class Dates extends Facade
{
    /**
     * Get the registered name of the component.
     *
     * @return string
     */
    protected static function getFacadeAccessor() { return 'date-service'; }
}

DateServiceProvider.php

class DateServiceProvider extends ServiceProvider
{
    /**
     * Register any application services.
     *
     * @return void
     */
    public function register()
    {
        $this->app->singleton('date-service', function()
        {
            return new DateTimeService;
        });
    }
}
