firebase - Can Cloud Firestore onSnapshot() only trigger on changes, and not get the initial state?

Question

The documentation says:

You can listen to a document with the onSnapshot() method. An initial call using the callback you provide creates a document snapshot immediately with the current contents of the single document. Then, each time the contents change, another call updates the document snapshot.

I just want my listener to fire when the data changes. I don't want it to fire when the app loads, to get the initial state of the data. Any suggestions?
