Not by default, Firebase doesn't provide it. You would need to load all the data or save and maintain a counter on the database. The workaround for pagination would be

var start = 0;
var end = 10;

var response = await _client.GetAsync("path", QueryBuilder.New().OrderBy("field_name").StartAt(start.ToString()).EndAt(end.ToString()));
var result = response.ResultAs<List<TestClass>>();
