How can I customize a FlatList in React Native?

You can customize a FlatList by using props like renderItem, keyExtractor, and style. What specific customization do you have in mind?

I want to change the item layout and add some animations.

You can create a custom item layout by defining your own component for renderItem. For animations, consider using the Animated API.

Can you show me an example of a custom item component?

Sure! Here's a simple example:

const MyItem = ({ item }) => {
  return (
    <View style={{ padding: 20, backgroundColor: 'lightblue', marginVertical: 10 }}>
      <Text>{item.title}</Text>
    </View>
  );
};

You can use this in your FlatList's renderItem prop.

What about adding a loading spinner while fetching data?

You can use a state variable to manage loading. Set it to true while fetching data and render a spinner conditionally.
