First stable release of yiisoft/request-provider was tagged.
The package provides current PSR-7 request as a dependency.
When you need current request, get RequestProviderInterface as dependency and obtain the request from it:
use \Yiisoft\RequestProvider\RequestProviderInterface;

final class MyService
{
public function __construct(
private readonly RequestProviderInterface $requestProvider
) {
}

public function doIt()
{
$request = $this->requestProvider->get();
// ...
}
}
