UserItem typedef
It shows the current User preview.
The widget uses a StreamBuilder to render the user information image as soon as it updates.
Usually you don't use this widget as it's the default user preview used by StreamUserListView.
The widget renders the ui based on the first ancestor of type StreamChatTheme. Modify it to change the widget appearance.
Implementation
@Deprecated("Use 'StreamUserItem' instead")
