Gallery

Renders image attachments inside MessageList.

Best Practices

Keep gallery layouts compact to avoid oversized rows.
Use setOverlay and gallery context helpers instead of custom image viewers.
Handle mixed image/video attachments gracefully.
Respect preventPress when you need to disable full-screen viewing.
Avoid heavy image processing in render; rely on caching or native components.

Basic Usage

Replace the default UI via WithComponents.

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

<WithComponents overrides={{ Gallery: () => <Gallery preventPress /> }}>
  <Channel channel={channel}>
    <MessageList />
    <MessageComposer />
  </Channel>
</WithComponents>;
