Install for React Native and Expo

Expo
React Native

npx expo install @superflag-sh/react-native @react-native-async-storage/async-storage

npm install @superflag-sh/react-native @react-native-async-storage/async-storage
npx pod-install

The current package requires React 18+, React Native >=0.65 <1, and @react-native-async-storage/async-storage >=1.0.0.

Add a public client key

Expo can expose the environment’s pub_ key:

EXPO_PUBLIC_SUPERFLAG_CLIENT_KEY=pub_...

Mobile applications are public clients. Never ship an sdk_, admin_, or cli_ credential in an app binary or OTA update.

Mount the provider

import { SuperflagProvider } from "@superflag-sh/react-native"

export default function App() {
  return (
    <SuperflagProvider
      clientKey={process.env.EXPO_PUBLIC_SUPERFLAG_CLIENT_KEY}
      targetingKey="install-or-user-id"
    >
      <Application />
    </SuperflagProvider>
  )
}

The package is tested through a clean Expo production Metro bundle and Hermes bytecode compilation. The SDK itself does not require a custom native module; AsyncStorage is the native peer used for persistent caching.
