Reference documentation and code samples for the Firestore v1 API class AggregationResult.
The result of a single bucket from a Firestore aggregation query.
The keys of aggregate_fields are the same for all results in an aggregation
query, unlike document queries which can have different fields present for
each result.
The result of the aggregation functions, ex: COUNT(*) AS total_docs.
The key is the
[alias][google.firestore.v1.StructuredAggregationQuery.Aggregation.alias]
assigned to the aggregation function on input and the size of this map
equals the number of aggregation functions in the query.
