OverlayProvider

The OverlayProvider is the top-level Stream Chat for React Native component and wraps all other components provided by the SDK. The OverlayProvider allows users to interact with messages on long press above the underlying views, use the full screen image viewer, and use the AttachmentPicker alongside the keyboard.

General Usage

The OverlayProvider should wrap all other Stream Chat for React Native components and in most cases the majority of your application.

Note: For detailed implementation instructions of the OverlayProvider with navigation please refer to the Navigation guide.

import { StreamChat } from "stream-chat";
import { ChannelList, Chat, OverlayProvider } from "stream-chat-react-native";

const client = StreamChat.getInstance("api_key");

export const App = () => (
  <OverlayProvider>
    <Chat client={client}>
      <ChannelList />
    </Chat>
