A Widget To Display Common Channel Details
|
|
|
|
Find the pub.dev documentation [here](https://pub.dev/documentation/stream_chat_flutter/latest/stream_chat_flutter/StreamChannelHeader-class.html)
|
|
|

|
|
|
### Background
|
|
|
|
When a user opens a channel, it is helpful to provide context of which channel they are in. This may
|
|
be in the form of a channel name or the users in the channel. Along with that, there also needs to be
|
|
a way for the user to look at more details of the channel (media, pinned messages, actions, etc.) and
|
|
preferably also a way to navigate back to where they came from.
|
|
|
|
To encapsulate all of this functionality into one widget, the Flutter SDK contains a `StreamChannelHeader`
|
|
widget which provides these out of the box.
|
|
|
|
### Basic Example
|
|
|
|
Let's just add a `StreamChannelHeader` to a page with a `StreamMessageListView` and a `StreamMessageInput` to display
|
|
and send messages.
|
|
|
|
```dart
|
|
class ChannelPage extends StatelessWidget {
|
|
const ChannelPage({
|
|
Key key,
|
|
}) : super(key: key);
|
|
|
|
@override
|
|
Widget build(BuildContext context) {
|
|
return Scaffold(
|
|
appBar: StreaChannelHeader(),
|
|
body: Column(
|
|
children: <Widget>[
|
|
Expanded(
|
|
child: StreamMessageListView(
|
|
threadBuilder: (_, parentMessage) {
|
|
return ThreadPage(
|
|
parent: parentMessage,
|
|
);
|
|
},
|
|
),
|
|
),
|
|
StreamMessageInput(),
|
|
],
|
|
),
|
|
);
|
|
}
|
|
}
|
|
```
|
|
|
|
### Customizing Parts Of The Header
|
|
|
|
The header works like a `ListTile` widget.
|
|
|
|
Use the `title`, `subtitle`, `leading`, or `actions` parameters to substitute the widgets for your own.
|
|
|
|
```dart
|
|
//...
|
|
StreamChannelHeader(
|
|
title: Text('My Custom Name'),
|
|
),
|
|
```
|
|
|
|
|
|
|
|
### Showing Connection State
|
|
|
|
The `StreamChannelHeader` can also display connection state below the tile which shows the user if they
|
|
are connected or offline, etc. on connection events.
|
|
|
|
To enable this, use the `showConnectionStateTile` property.
|
|
|
|
```dart
|
|
//...
|
|
StreamChannelHeader(
|
|
showConnectionStateTile: true,
|
|
),
|
|
```
|
