Summary:
I thought it would be useful to help clear out references to no longer used styles and also catch typos on style names to have flow error when we try to access a style that isn't defined.
Example:
```javascript
export default class AuthenticationScreen extends React.Component {
render() {
// This throws an error because `continer` is misspelled
return (
<View style={styles.continer} />
)
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
},
}
```
```javascript
export default class AuthenticationScreen extends React.Component {
render() {
// This throws an error because no fancyContainer style is defined
return (
<View style={[styles.container, styles.fancyContainer]} />
)
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
},
}
```

UIExplorer
The UIExplorer is a sample app that showcases React Native views and modules.
Running this app
Before running the app, make sure you ran:
git clone https://github.com/facebook/react-native.git
cd react-native
npm install
Running on iOS
Mac OS and Xcode are required.
- Open
Examples/UIExplorer/UIExplorer.xcodeprojin Xcode - Hit the Run button
See Running on device if you want to use a physical device.
Running on Android
You'll need to have all the prerequisites (SDK, NDK) for Building React Native installed.
Start an Android emulator (Genymotion is recommended).
cd react-native
./gradlew :Examples:UIExplorer:android:app:installDebug
./packager/packager.sh
Note: Building for the first time can take a while.
Open the UIExplorer app in your emulator.
See Running on Device in case you want to use a physical device.
Running with Buck
Follow the same setup as running with gradle.
Install Buck from here.
Run the following commands from the react-native folder:
./gradlew :ReactAndroid:packageReactNdkLibsForBuck
buck fetch uiexplorer
buck install -r uiexplorer
./packager/packager.sh
Note: The native libs are still built using gradle. Full build with buck is coming soon(tm).
Built from source
Building the app on both iOS and Android means building the React Native framework from source. This way you're running the latest native and JS code the way you see it in your clone of the github repo.
This is different from apps created using react-native init which have a dependency on a specific version of React Native JS and native code, declared in a package.json file (and build.gradle for Android apps).
