ChannelPreview class
Shows a preview for the current Channel.
Uses a StreamBuilder to render the channel information image as soon as it updates.
It is not recommended to use this widget directly as it is the
default channel preview widget used by ChannelListView.
The UI is rendered based on the first ancestor of type StreamChatTheme. Modify it to change the widget's appearance.
