React Native SafeAreaView background color - How to assign two different background color for top and bottom of the screen?

I was able to solve this using a version of Yoshiki's and Zach Schneider's answers. Notice how you set the top SafeAreaView's flex:0 so it doesn't expand.

render() {
  return (
    <Fragment>
      <SafeAreaView style={{ flex:0, backgroundColor: 'red' }} />
      <SafeAreaView style={{ flex:1, backgroundColor: 'gray' }}>
        <View style={{ flex: 1, backgroundColor: 'white' }} />
      </SafeAreaView>
    </Fragment>
  );
}

I was able to solve this by using some absolute position hacking. See the following tweak. Not future proof by any means, but it solves the problem I had.

import {
  ...
  SafeAreaView,
  View
} from 'react-native';
class Main extends React.Component {
  render() {
    return (
      <SafeAreaView style={styles.safeArea}>
        <App />
        <View style={styles.fixBackground} />
      </SafeAreaView>
    )
  }
}
const styles = StyleSheet.create({
  ...,
  safeArea: {
    flex: 1,
    backgroundColor: '#FF5236'
  },
  fixBackground: {
    backgroundColor: 'orange',
    position: 'absolute',
    bottom: 0,
    right: 0,
    left: 0,
    height: 100,
    zIndex: -1000,
  }
})

I ran into the same problem and was able to solve with the following:

const styles = StyleSheet.create({
  outerWrapper: {
    backgroundColor: 'orange',
  },
  innerWrapper: {
    backgroundColor: 'black',
  },
});

// snip

const MyComponent = ({ content }) => (
  <View style={styles.outerWrapper}>
    <SafeAreaView />

    <SafeAreaView style={styles.innerWrapper}>
      {content}
    </SafeAreaView>
  </View>
);

The outerWrapper applies the orange background color at the top. The first <SafeAreaView /> pushes the second one down so that it starts at the beginning of the "safe area" (below the status bar). Then the second SafeAreaView takes up the rest of the screen (including the bottom "unsafe" area) and gives it the black background color.
