FileAttachment

Renders file attachments inside MessageList.

Best Practices

Keep file rows compact and readable.
Validate file size/type before rendering heavy previews.
Use consistent icons and sizes across your app.
Customize via WithComponents instead of editing internals.

Basic Usage

Replace the default UI via WithComponents.

Example: change the file attachment icon size.

import { WithComponents, FileAttachment } from "stream-chat-react-native";

<WithComponents
  overrides={{
    FileAttachment: () => <FileAttachment attachmentIconSize="lg" />,
  }}
>
  <Channel channel={channel}>
    <MessageList />
    <MessageComposer />
  </Channel>
</WithComponents>;
