An implementation of StreamBuilderBase that folds new stream events into a summary and builds with the summary of stream events seen so far. Use this class instead of StreamBuilder if you need a widget that represents the summary of all stream event so far instead of just the latest element. A common use case would be building a ListView with elements fetched asynchronously from a paginated Database Query.

T is the type of stream events.

S is the type of interaction summary. Summaries are wrapped in AsyncSnapshot to give the builder access to the ConnectionState. See also:

  • StreamBuilder, which is specialized for the case where only the most recent interaction is needed for widget building.
  • StreamBuilderBase, an abstract class that enables greater customization of summary and connection state behavior.

Any contributions to this package are highly welcome.
