MessageSearchListCore
A Widget For Displaying Message Searches
Background
The UI SDK of Stream Chat supplies a MessageSearchListView
class that builds a list of channels fetching
according to the filters and sort order given. However, in some cases, implementing novel UI is necessary
that cannot be done using the customization approaches given in the widget.
To do this, we extracted the logic required for fetching channels into a 'Core' widget - a widget that fetches channels in the expected way via the usual parameters but does not supply any UI and instead exposes builders to build the UI in situations such as loading, empty data, errors, and on data received.
Basic Example
MessageSearchListCore
is a simplified class that allows searching for
messages across channels while exposing UI builders.
A MessageSearchListController
is used to load and paginate data.
class MessageSearchPage extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Scaffold(
body: MessageSearchListCore(
messageQuery: _messageFilter,
filters: _channelsFilter,
limit: 20,
),
);
}
}
Make sure to have a MessageSearchBloc
ancestor in order to provide the
information about the messages.
