When updating the data passed to the FlatList, it will re-render all items from the beginning. How to prevent this behavior, we need to render only the newly added items without affecting the existing ones.

Hey! Excelente video!

Do you can upgrade your video about RevenueCat with React Native(Expo) principally in Android, because exists some changes in new versions and don't work perfectly. An example is when I show offerings in Android, unfortunally, don't show in my screen.

This is amazing thank you,

Quick one, if a result from the JSON didn't have an image for example, how could we only display the text for that result and skip the image view?

<Image source={{ uri: character.image }} style={styles.image} />

Did you ever figure out why duplicate items were showing up in the list? I'm running into similar issues

Thanks sir for this video.

In this if list is large then at the time of pull to refresh array is not clearing and when api response came data is duplicating.
For that i need to add list dependency in useEffect and once list clear calling api.
