Builds, integrates, migrates, and audits Stream Chat, Stream Video, and Stream Feeds in React Native CLI and Expo apps. Use when scaffolding a new RN/Expo Chat, Video, or Feeds app, adding Stream to an existing RN app, upgrading a Stream SDK version (stream-chat-react-native v8 to v9, Feeds v2 to v3), migrating from Sendbird (@sendbird/chat, @sendbird/uikit-react-native), answering RN/Expo SDK how-to questions, or customizing Stream RN UI. Triggers on React Native, Expo, Expo Router, stream-chat-react-native, stream-chat-expo, @stream-io/video-react-native-sdk, @stream-io/feeds-react-native-sdk, channel list, message list, MessageComposer, threads, attachment picker, audio messages, offline support, push notifications, video call, livestream, audio room, ringing, CallContent, ParticipantView, activity/timeline/notification feed, useCreateFeedsClient, StreamFeeds, comments, reactions, follows, and theming. React Native and Expo only - not web React (use stream-react), not Moderation review UI.
