numColumns stopped working after RN 0.77 on iOS

[brunozampirom]

Current behavior

After updating my app to React Native 0.77, my lists with more than one column are not working, they are always being rendered with only one column. Only happening on iOS, Android is fine.

Expected behavior

Correctly render more than one column

To Reproduce

const DATA = [
    {
        title: "First Item",
    },
    {
        title: "Second Item",
    },
    {
        title: "Third Item",
    },
    {
        title: "Fourth Item",
    },
];

const MyList = () => {
    return (
        <FlashList
            data={DATA}
            numColumns={2} // here
            renderItem={({ item }) => <Text style={{ margin: 6 }}>{item.title}</Text>}
            estimatedItemSize={200}
        />
    );
};

Platform:

• iOS
• Android

Environment

"@shopify/flash-list": "^1.7.3",
"react-native": "^0.77.0",

I just updated to 0.77 because of bugs with expo and Xcode 16.3 and this is the last outstanding bug 🫠
