描述
Description
I attempt to add a alert popup box when user refreshes the FlatList, but it seems that Alert.alert will interfere with Animated.FlatList's animation and will cause it doesn't bounce back
Steps to reproduce
Minimal code to reproduce:
import { Animated, StyleSheet, Alert, Dimensions } from 'react-native';
import { View, Text } from 'react-native';
function App() {
return (
<Animated.FlatList
data={["item1", "item2", "item3"]}
renderItem={({ item }) => <Text style={{fontSize: 20, margin: 10, padding: 10}}>{item}</Text>}
style={{ position: "relative", borderColor: "black", margin: 10, padding: 10, borderWidth: 1, borderRadius: 10 }}
refreshing={false}
onRefresh={() => {
Alert.alert(
"Alert",
"Sure?",
[
{text: "cancel", style: "cancel", onPress: () => {}},
{
text: "ok",
onPress: () => {
console.log("ok");
},
},
],
);
}}
/>
);
}
const { width, height } = Dimensions.get('window');
export default function HomeScreen() {
return (
<View style={styles.container}>
<View style={[styles.box, {
position: 'absolute',
top: height*0.25,
left: width*0.25,
}]}>
<App />
</View>
</View>
);
}
const styles = StyleSheet.create({
container: {
flex: 1,
backgroundColor: 'white',
},
box: {
// backgroundColor: 'blue',
opacity: 0.5,
},
titleContainer: {
flexDirection: 'row',
alignItems: 'center',
gap: 8,
},
stepContainer: {
gap: 8,
marginBottom: 8,
},
reactLogo: {
height: 178,
width: 290,
bottom: 0,
left: 0,
position: 'absolute',
},
});

There's no crash so I don't think log will be useful

调研方向
从 Snack 复现开始,在 iOS runtime 上运行它,重点关注 Animated.FlatList 调用 Alert.alert 时的 onRefresh 行为。确认 alert 出现后列表无法恢复回弹,并在带有 alert 的刷新恢复预期的回弹动画时,认为该 issue 已完成。
