Description
Exceeded max renders without commit. This might mean that you have duplicate keys in your keyExtractor output or your list is nested in a ScrollView causing a lot of items to render at once. If it's none of those and is causing a real issue or error, consider reporing this on FlashList Github
After updating to 2.2.0, I got this error on IOS. Tried to wrap FlashList not inside ScrollView and provided keyExtractor also, but still it doesn't work!
- expo: 54
- @shopify/flash-list: "2.2.0"
