  • Have you experienced any bugs using ListItem within FlatList ? I have implemented it like you did and when i scroll to bottom multiple times, the app crashes. No error logs are displayed. I removed ListItem from FlatList and rendered View components instead and there are no more crashes. Seems like ListItem is making this behaviour.

  • Quick question, I realize this might not have been around in previous versions of RN, but would it be better to use prevState when updating state variables using their current state? For instance:

    this.setState((prevState) => {
    return {
    data: prevState.page === 1 ? resp : […prevState.data, …resp]
    }
    });

  • Thanks for the nice tutorial Spencer! Exactly what I needed. I'm surprised to see how easy to use FlatList is (I've worked with Swift collection view before).

  • In renderItem, we're destructuring the argument with { item } syntax, but the object we're receiving is structured as:
    {
    info: {
    item: itemT,

    }
    }
    (source: https://facebook.github.io/react-native/docs/flatlist.html#renderitem)

    Why does the { item } syntax work, when `item` is actually under `info` in the data we receive?
