FlatFeedCore class

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

FlatFeedCore extends GenericFlatFeedCore with default types of:

User, String, String, String.

Under most circumstances FlatFeedCore is all you need to use.

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');
        }
      ),
    );
  }
}
