​
React Native SDK Installation

The @superflag-sh/react-native package provides feature flags and remote config for React Native and Expo applications.

​
Requirements

  • React Native 0.70+
  • React 18 or higher
  • Expo SDK 49+ (if using Expo)
  • @react-native-async-storage/async-storage 1.0+

​
Installation

npx expo install @superflag-sh/react-native @react-native-async-storage/async-storage
AsyncStorage is required. The React Native SDK needs AsyncStorage for persistent caching. Make sure to install @react-native-async-storage/async-storage.

​
Platform Support

The React Native SDK works on:
  • iOS (14.0+)
  • Android (API 21+)
  • Expo (SDK 49+)

​
Bundle Size

  • ~6 KB minified (gzipped)
  • Zero dependencies (except peer deps: React, AsyncStorage)
  • Fully tree-shakeable ES modules

​
TypeScript Support

The SDK is written in TypeScript with full type definitions included. 
import { useFlag } from '@superflag-sh/react-native'

// Type-safe hooks
const enabled = useFlag<boolean>('feature-flag', false)
const config = useFlag<{ theme: string }>('ui-config', { theme: 'light' })
