There is no method in the Firestore client-side SDKs to get all collections (or subcollections under a specific document). Such API does exist in the server-side SDKs, but not in the client-side SDKs.

See:

• Fetching all collections in Firestore
• How to get all of the collection ids from document on Firestore?

So you'll need to know the collections already, typically by changing your data model. For example by creating a document for each list's metadata, and then storing the list items in a subcollection with a known name under that document. That way you can get all lists by querying for the documents, which is possible within the API.
