The ReviewModel is a read-only model used to fetch reviews about a Place . The model incrementally fetches. The number of reviews which are fetched at a time is specified by the batchSize property. The total number of reviews available can be accessed via the totalCount 特性。

要使用 ReviewModel we need a view and a delegate. In this snippet we see the setting up of a ListView 采用 ReviewModel model and a delegate.
