Check if a folder exists of a certain name in Firebase storage

Question

In the Firebase Storage, I have a folder named uploads/. Inside that folder, I have multiple folders named after the userIds of the registered user

Cloud Storage for Firebase doesn't have event listners like Realtime Database. You're trying to do something that isn't supported (which is why you're getting a compiler error). Please see the API documentation for StorageReference to find out what you can do with that object.

On top of that, there is no way to check if a "folder" exists in Cloud Storage. Cloud Storage doesn't actually have any folders. It just has files with path components that look like folders.

If you want to know if a file exists (not a "folder"), then you could use the getMetadata method on a StorageReference that refers to the file.
