As you can see in the image below, I have to give some top margin in order to "not" hide my half of the content under the navigation header, isn't header supposed to be a "safe area" for the below content, to be on the safe side I provided the SafeAreaView but still my content goes under the Header and unfortunately I have to give some hardcoded margin top value to avoid hiding.

The above image is when I comment marginTop.

Above image is when I add marginTop: 70

Code:

NotificationScreen.tsx:

import {
  View,
  SafeAreaView,
  Text,
  StatusBar,
} from 'react-native';
import Animated, {FadeIn, FadeOut} from 'react-native-reanimated';
import OrderItem from '../../components/OrderItem';

const NotificationScreen = () => {
  const [orders, setOrders] = useState([]);

  useEffect(() => {
    // calling API...
  }, []);

  return (
    <SafeAreaView style={styles.container}>
      <StatusBar backgroundColor="transparent" translucent />

      <Text style={{color: 'lightgray', fontSize: 18}}>My Orders: </Text>

      <Animated.FlatList
        data={orders}
        entering={FadeIn}
        leaving={FadeOut}
        contentContainerStyle={{
          alignItems: 'center',
        }}
        keyExtractor={(_: any, index) => 'key' + index}
        renderItem={({item}) => <OrderItem key={item.id} data={item} />}
      />
    </SafeAreaView>
  );
};

const styles = StyleSheet.create({
  container: {
    marginTop: 70, // if I remove this, the content goes under the header as shown in image.
    flex: 1,
    padding: 10,
    backgroundColor: COLORS.primary,
  },
});

export default NotificationScreen;

One more query, why my OrderItem not taking the full width of FlatList (see image, the gray box is not takin the full width...), I have provided width: 100% to my OrderItem container:

OrderItem.tsx:

const OrderItem = ({data}) => {
  return (
    <View style={styles.container}>
      <View style={styles.textBlock}>
        <Text style={styles.label}>Strategy: </Text>
        <Text style={styles.info}>{data.strategyTitle}</Text>
      </View>
      // ... same views as shown in image
    </View>
  );
};

const styles = StyleSheet.create({
  container: {
    width: '100%',
    paddingVertical: 10,
    paddingHorizontal: 10,
    alignItems: 'center',
    justifyContent: 'space-between',
    backgroundColor: COLORS.lightGray,
    borderRadius: 10,
  },
  textBlock: {
    flexDirection: 'row',
    alignItems: 'center',
    justifyContent: 'space-between',
  },
  label: {
    color: 'grey',
    fontSize: 16,
  },
  info: {
    color: 'white',
    fontSize: 16,
  },
});

export default OrderItem;
