StreamMessageListView

A Widget For Displaying A List Of Messages

Find the pub.dev documentation here

Background#

Every channel can contain a list of messages sent by users inside it. The StreamMessageListView widget displays the list of messages inside a particular channel along with possible attachments and other message attributes (if the message is pinned for example). This sets it apart from the StreamMessageSearchListView which may not contain messages only from a single channel and is used to search for messages across many.

Basic Example#

The StreamMessageListView shows the list of messages of the current channel. It has inbuilt support for common messaging functionality: displaying and editing messages, adding / modifying reactions, support for quoting messages, pinning messages, and more.

An example of how you can use the StreamMessageListView is:

class ChannelPage extends StatelessWidget {
const ChannelPage({
Key key,
}) : super(key: key);

@override
Widget build(BuildContext context) {
return Scaffold(
appBar: StreamChannelHeader(),
body: Column(
children: <Widget>[
Expanded(
child: StreamMessageListView(),
),
StreamMessageInput(),
],
),
);
}
}

Enable Threads#

Threads are made of a parent message and replies linked to it. To enable threading, the SDK requires you to supply a threadBuilder which will supply the page when the thread is clicked.

StreamMessageListView(
threadBuilder: (_, parentMessage) {
return ThreadPage(
parent: parentMessage,
);
},
),

The StreamMessageListView itself can render the thread by supplying the parentMessage parameter.

StreamMessageListView(
parentMessage: parent,
),

Building Custom Messages#

You can also supply your own implementation for displaying messages using the messageBuilder parameter.

note

To customize the existing implementation, look at the StreamMessageWidget documentation instead.

StreamMessageListView(
messageBuilder: (context, details, messageList, defaultImpl) {
// Your implementation of the message here
// E.g: return Text(details.message.text ?? '');
},
),
