Attachment

Renders message attachments inside MessageList. This is the default component for the Attachment prop.

It selects the correct renderer by attachment type (card, Giphy, file, etc.). For customization, use type-specific props like Giphy, Gallery, UrlPreview, or FileAttachment. See Attachment Customization for details.

Best Practices

• Prefer type-specific overrides (Gallery, FileAttachment) over replacing the whole Attachment component.
• Handle unknown or custom attachment types gracefully.
• Keep attachment rendering lightweight to avoid list jank.
• Use AttachmentActions for supported actions instead of custom tap logic.
• Ensure URL previews and media rendering are consistent with your app theme.
