My Flutter app on web has been using Firebase Cloud Messaging for a long time without error. Today, with no changes, it is giving the following error:

Error: [firebase_messaging/failed-service-worker-registration] Messaging: We are unable to register the default service worker. Failed to register a ServiceWorker for scope ('http://localhost:50093/firebase-cloud-messaging-push-scope') with script ('http://localhost:50093/firebase-messaging-sw.js'): The Service Worker system has shutdown.

Can anyone explain why this error is occurring now? I suspect something must have changed on Firebase's end, because my code has not changed.

If you're using an older version of Firebase Cloud Messaging plugin, you might need to follow this setup guide to create a default app settings for web. On current version of FCM, you can follow this initialization guide to add the FCM plugin on your app.
