Google's short URL service goo.gl was launched on December 14, 2009, and it has been 9 years since the service was closed. The existing goo.gl link is still available, but the new link has not been created. Google recommends that developers can turn to their Firebase dynamic links, and regular users can only switch to other short URL services.
After the service is closed, it will be replaced by a new Firebase dynamic link, which is a "smart URL" that can easily "go to a user anywhere in the iOS or Android app" in addition to the webpage, apparently In Google's eyes it will be much better than the original goo.gl.
