Pull-to-refresh gesture works smoothly (if implemented)

When a feed of dynamic data has no RefreshControl, users have no way to force fresh content — they back out of the screen and re-enter just to trigger a fetch, or they assume the app is broken. A stuck refreshing={true} that never resets is worse: the spinner burns indefinitely, users wait, then force-quit. Both patterns inflate perceived load time and trigger abandonment before the real content loads.

Add RefreshControl to every FlatList or ScrollView rendering dynamic data, and reset the refreshing flag in a finally block so network errors do not strand the spinner:

const [refreshing, setRefreshing] = useState(false);
const onRefresh = async () => {
  setRefreshing(true);
  try { await fetchData(); } finally { setRefreshing(false); }
};
<FlatList refreshControl={<RefreshControl refreshing={refreshing} onRefresh={onRefresh} />} />
