I am trying to get the email (in this case [email protected]) however I don't see any method I can use that gets me the name of the child instead of the value.

Answer 1

In this case the email is the key of a nested object. You need to iterate over the collection documents and use their id as email

 firestore.collection("Users").get().result.documents.forEach { 
    Log.d("Key", "${it.key}")   
}

You can also use higher-order function to transform the documents, associate (using the email) and deserialize the data.
