VirtualizedMessageListContext

VirtualizedMessageListContext is provided by VirtualizedMessageListContextProvider, which wraps the content rendered by VirtualizedMessageList. It exposes the minimal list-level API that custom components rendered inside the virtualized list need — currently a scrollToBottom helper.

Best Practices

• Use useVirtualizedMessageListContext for controls rendered inside a VirtualizedMessageList. For the standard MessageList, use useMessageListContext instead — the two lists provide different contexts.
• Use scrollToBottom() for “jump to latest” style controls rendered inside the virtualized subtree.
• Keep custom controls lightweight to avoid virtualization jitter.
• Avoid assumptions about off-screen DOM nodes because virtualization unmounts them.

Basic Usage

import { useVirtualizedMessageListContext } from "stream-chat-react";

const CustomComponent = () => {
  const { scrollToBottom } = useVirtualizedMessageListContext();

  return <button onClick={scrollToBottom}>Jump to bottom</button>;
};
