Description

Hi There, I am using TouchableOpacity inside the FlatLis. And the FlatList data has 500 objects. when the data appearing on the screen, it is showing a warning as below

function for gating data const CallLogsAPI = async (employee_id) => { try { // setIsLoading(true) let res = await axios.post(${BASE_URL}/Temp/getCallLogs, { employee_id }, { timeout: 3000 }) let data = res.data.data // console.log('apiLogData', data) SetApiLogData(data) setIsLoading(false) }

    catch (e) { console.log("bb", e) }
    setIsLoading(false)
} 

return data to screen:

return ( <View style={{ height: '100%' }}> {/* { isLoading && <View style={styles.loading}> <ActivityIndicator size={50} color="dimgray" animating={isLoading} /> </View> } <View style={styles.sync}> <Icon name='sync-circle' size={70} color='#2196F3' onPress={() => { setIsLoading(true); GetDeviceLogs(employee_id) }} /> </View> */}

        <FlatList
            data={apiLogData}
            initialNumToRender='15'
            refreshControl={
                <RefreshControl
                  refreshing={isLoading}
                  onRefresh={()=>{setIsLoading(true); GetDeviceLogs(employee_id)}}
                  colors={['red','blue',"yellow"]}
                />}
            renderItem={({ item }) => {

                return (
                    <View style={[styles.card, styles.elevation]}>

                        <View style={{ flex: 2, flexDirection: "row", justifyContent: "space-between" }}>

                    </View>
                )
            }
            }
        />

Same issue here when rendering this item:

<TouchableOpacity
  key={item.id}
  onPress={async () => setResult(await getPickedImageResult(item))}>
  <Image
    style={{ width: size, height: size }}
    source={{ uri: item.uri, width: item.width, height: item.height }}
  />
</TouchableOpacity>

For me the warning triggers after some scrolling, sometimes after rendering 70 items, sometimes after more.

Changing the TouchableOpacity to a Pressable component no more triggers the warning so I assume this is caused by TouchableOpacity?

[mjmasn]

Yeah this seems to be caused by a change to TouchableOpacity in React Native 0.69....

https://github.com/facebook/react-native/commit/3eddc9abb70eb54209c68aab7dbd69e363cc7b29

(flattenStyle(prevProps.style)?.opacity !==
        flattenStyle(this.props.style)?.opacity) !==
        undefined

is always going to evaluate to true, therefore calling this._opacityInactive(250); as many times as the component is (re)rendered.

Quick fix: remove the !== undefined from node_modules/react-native/Libraries/Components/Touchable/TouchableOpacity.js then run npx patch-package react-native

[Charles-Johnson]

I get a similar error message but with react-native 0.68

VirtualizedList: You have a large list that is slow to update - make sure your renderItem function renders components that follow React performance best practices like PureComponent, shouldComponentUpdate, etc. Object {

@mjmasn that typo seems to be addressed here: https://github.com/facebook/react-native/pull/35387

[mjmasn]

@FrikkieSnyman yep 👍 I imagine it'll be released with React Native 0.72 unless it gets cherry picked onto 0.71 in the meantime

[linaia]

With react-native 0.71.3 (expo sdk48) it is not fixed, so you still have to patch it.

This issue is stale because it has been open 180 days with no activity. Remove stale label or comment or this will be closed in 7 days.

[linaia]

It's fixed in 0.72.6 (used by expo sdk49)

if (
      this.props.disabled !== prevProps.disabled ||
      // $FlowFixMe[underconstrained-implicit-instantiation]
      flattenStyle(prevProps.style)?.opacity !==
        // $FlowFixMe[underconstrained-implicit-instantiation]
        flattenStyle(this.props.style)?.opacity
    ) {
      this._opacityInactive(250);
    }

You can close the issue.

Any updates? Experiencing this in v0.73.4

[nguptaesaral]

Any updates? Experiencing this in v0.73.4

Use Pressable instead of TouchableOpacity.

[saczx]

Same in v0.73.6, change TouchableOpacity to Pressable, didn't work at all

[yummyelin]

seeing same error in v0.73.8 for <TextInput /> given to ListHeaderComponent
