Steps to Reproduce

Having a shadow inside a flat list(in footerComponent, headerComponent, emptyListComponent and Item) using elevation for android shows nothing, while using shadow props for iOS works perfectly.

Expected Behavior

There should be a shadow in android.

Actual Behavior

No shadow is shown.

Reproducible Demo

renderItem = ({ item }) => {
    return (
        <View style={{
            shadowColor: '#000',
            shadowOffset: { width: 0, height: 2 },
            shadowOpacity: 0.1,
            shadowRadius: 1.5,
            elevation: 3,
            borderWidth: 1,
            borderColor: '#ccc',
            flex: 1,
            height: 42,
            backgroundColor: '#fff',
        }} />
    );
}

render() {
    return (
        <FlatList
            data={this.props.data}
            keyExtractor={item => item.id}
            renderItem={this.renderItem}
        />
    );
}

https://facebook.github.io/react-native/docs/shadow-props.html shadow props are only for iOS. Ran into the same issue.

Shadow is for iOS but the elevation should draw a shadow, right?

elevation: 3,

@nim23 I am using shadow props for iOS and elevation for Android, which normally should add a shadow to the view I am applying it on.

@am-een can u try this?

const StyleElements = () => (
  <ScrollView style={styles.container} contentContainerStyle={styles.content}>
    <View elevation={3}>
      <View style={styles.cardContent}>
        <Text>{'Hola'}</Text>
      </View>
    </View>
  </ScrollView>
);

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: 'white',
  },
  content: {
    flex: 1,
    paddingHorizontal: 20,
    paddingTop: 10,
  },
  cardContent: {
    alignItems: 'center',
    justifyContent: 'center',
    alignSelf: 'stretch',
    height: 200,
  },
});

elevation can be applied as a View prop as well.

I upgraded react-native and it looks like it has been fixed in the rn-0.50.2
Closing issue.
