Expo UI

In my ~/github directory, run git clone [email protected]:expo/expo.git. This takes a while, as it has to download 3 GiB

Navigate to cd expo and run yarn, this might take a minute Navigate to: cd apps/native-component-list folder Run yarn start which should start the Metro server

• For web: run yarn web and it will show in your browser in localhost:8081
• For Android:
  • We cannot use Expo Go (maybe that is supposed to work, but gives an error), so we need to build the app locally first
  • Update the versions of two dependencies in package.json that fix errors with React Native 0.77: "@shopify/flash-list": "1.7.3", "@shopify/react-native-skia": "1.11.3",
  • Remove expo-updates completely from package.json, it will give you an error related to kspVersion otherwise
  • Remove the config.serializer.getPolyfills section from metro.config.js
  • run yarn again
  • run yarn android, if you are using Java 17 you might get an error, go to android/gradle.properties and remove -XX:MaxPermSize=2048m from line 13
  • Another error might be in packages/expo-ui/android/build.gradle, packages/expo-maps/android/build.gradle and packages/expo-modules-core/android/build.gradle with the version of the Compose Gradle plugin. In buildscript add: ext { kotlinVersion = '2.0.21' }
  • Now the app will be bundled and started in your default Emulator
  • Click on the 'Components' tab in the tab bar
  • Click on the list item 'Expo UI'
  • Note: if you want to run the app on your real device, connect it via USB and run yarn android --device
• For iOS:
  • From expo/packages/expo-notifications/expo-module.config.js remove the "appDelegateSubscribers": ["PushTokenAppDelegateSubscriber"] line, as it will cause a build error
  • Now run yarn ios --device and select a device connected by USB cable (or just yarn ios and use a Simulator)
  • If you get an Untrusted Developer popup on your phone, go to Settings -> General -> VPN & Device Management -> Developer App and press the button to trust your app developer. Then re-run your yarn ios command.
  • Sometimes if you get weird build errors, it helps to open the project in Xcode (run open ios/ExpoAPIs.xcworkspace) and build from there, then you can also select an App Developer or Team if it asks about that
