GenericFlatFeedCore<A, Ob, T, Or> class

GenericFlatFeedCore is a simplified class that allows fetching a list of enriched activities (flat) while exposing UI builders.

FlatFeedCore is a core class that allows fetching a list of enriched activities (flat) while exposing UI builders. Make sure to have a FeedProvider ancestor in order to provide the information about the activities. Usually what you want is the convenient FlatFeedCore that already has the default parameters defined for you suitable to most use cases. But if you need a more advanced use case use GenericFlatFeedCore instead

Usage

class ActivityListView extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: FlatFeedCore(
        errorBuilder: (context, error) => Center(
            child: Text('An error has occurred'),
        ),
        emptyBuilder: (context) => Center(
            child: Text('Nothing here...'),
        ),
        loadingBuilder: (context) => Center(
            child: CircularProgressIndicator(),
        ),
        feedBuilder: (context, activities) {
          return Text('Your ListView/GridView of activities');
        }
      ),
    );
  }
}

The generic parameters can be of the following type:

  • A : actor can be an User, or a String
  • Ob : object can a String, or a CollectionEntry
  • T : target can be a String or an Activity
  • Or : origin can be a String or a Reaction or an User

To avoid potential runtime errors make sure they are the same across the app if you go the route of using Generic* classes
