4 | Flutter + React = Love 5 |

6 | 7 | This repo contains a proof-of-concept for adding React Native to an existing Flutter app for iOS and Android. 8 | 9 | It contains a basic Flutter app with added React Native brownfield integration. It leverages both platforms' abilities to host native platform views, which serve as the briding layer. 10 | 11 | ## Scope 12 | 13 | - [x] Basic React Native brownfield setup 14 | - [x] Added some popular React Native libraries: 15 | - [x] React Navigation 16 | - [x] Reanimated 17 | - [x] React Native WebView 18 | - [x] Functioning hot reload for both React Native and Flutter 19 | 20 | ## Running 21 | 22 | 1. Run `yarn install` 23 | 2. Install Cocoapods: `cd ios; pod install` 24 | 3. Start Metro bundler in the root folder: `yarn start` 25 | 4. Open the root folder in VS Code 26 | 5. In VS Code, open `main.dart` and open Run -> Start Debugging menu option 27 | 28 | ## Screenshots 29 | 30 | | iOS | Android | 31 | | :----------------------------------------------------------------------------------------------------------------------: | :--------------------------------------------------------------------------------------------------------------------------: | 32 | | | | 33 | 34 | ## References 35 | 36 | - [Flutter docs: Host a native iOS view](https://docs.flutter.dev/platform-integration/ios/platform-views) 37 | - [Flutter docs: Host a native Android view](https://docs.flutter.dev/platform-integration/android/platform-views) 38 | - [React Native docs: Integration with Existing Apps](https://reactnative.dev/docs/integration-with-existing-apps) 39 | - [React Native docs: Integration with Android Fragment](https://reactnative.dev/docs/integration-with-android-fragment) 40 | 41 | ## To Do 42 | 43 | - [ ] Support for React Native new architecture 44 | - [ ] Improve Flutter to React Native navigation to be more seamless 45 | - [ ] Add TypeScript support 46 | - [ ] Improved type safety and error handling on both Flutter and React Native side 47 | -------------------------------------------------------------------------------- /src/react-native-intro.js: -------------------------------------------------------------------------------- 1 | /** 2 | * Sample React Native App 3 | * https://github.com/facebook/react-native 4 | * 5 | * @format 6 | */ 7 | 8 | import React from "react"; 9 | import { 10 | SafeAreaView, 11 | ScrollView, 12 | StyleSheet, 13 | Text, 14 | useColorScheme, 15 | View, 16 | } from "react-native"; 17 | 18 | import { 19 | Colors, 20 | DebugInstructions, 21 | Header, 22 | LearnMoreLinks, 23 | ReloadInstructions, 24 | } from "react-native/Libraries/NewAppScreen"; 25 | 26 | function Section({ children, title }) { 27 | const isDarkMode = useColorScheme() === "dark"; 28 | return ( 29 | 30 | 38 | {title} 39 | 40 | 48 | {children} 49 | 50 | 51 | ); 52 | } 53 | 54 | /** 55 | * Default React Native intro component. 56 | */ 57 | export function ReactNativeIntro() { 58 | const isDarkMode = useColorScheme() === "dark"; 59 | 60 | const backgroundStyle = { 61 | backgroundColor: isDarkMode ?
