React Native FlatList not scrolling to end - react-native

Question

I've got (what I thought was) a simple FlatList which renders a list of Cards (code below)
Problem: the list renders, but won't scroll to fully display the last element in the list, OR to the content below the FlatList
What I've tried: basically everything in related SO questions:
Removing ALL styling
Wrapping the FlatList in a View or a ScrollView or both
Adding style={{flex: 1}} to the FlatList or wrappers (this causes **ALL* content to disappear)
Any ideas?
<FlatList
data={props.filteredProducts}
renderItem={({item}) => (
<TouchableOpacity onPress={() => props.addItemToCart(item)}>
<Card
featuredTitle={item.key}
image={require('../assets/icon.png')}
/>
</TouchableOpacity>
)}
keyExtractor={item => item.key}
ListHeaderComponent={
<SearchBar />
}
/>
...

Answer 1

Add style={{flex: 1}} for each View element who is a parent for FlatList.

Answer 2

I had the same issue and just found the solution. Add the prop ListFooterComponentby giving it a React element/component. I just passed a view with the preferable height and it worked for me perfectly.
Here is the code snippet:
<FlatList
data={DATA}
renderItem={({ item }) => (<ListItem itemData={item} />) }
keyExtractor={item => item.id}
ListFooterComponent={<View style={{height: 20}}/>}
/>
This works 100%!

The ultimate solution is ✔
Any view/subview that holds a flatlist must have a flex of 1 - Regardless of how deep.
So if you apply this and it's not working, check your styling and make sure there's no mistake somewhere.

I'm not sure if your scenario is exactly the same as one I encountered on a project a few months ago, but I noticed that I had to add a margin/padding (depends on what you prefer) to lift the bottom of the scrollable container. This was usually because a parent container seemed to interfere with the styling of the scrollable element.
Have you tried adding flexGrow: 1 to your styling in place of flex?

Answer 5

My case is a little different, in that I used FlatList inside bottom sheet provided by reanimated-bottom-sheet package. But the problem was the same: scrolling didn't show the last item properly.
The way I did was I calculated and set the height of the view that included the FlatList. To make it look better when there is bottom inset, I gave more bottom margin to the last item of the FlatList by doing like this:
<FlatList
data={results}
keyExtractor={(item) => item.name}
scrollEnabled={bottomSheetIndex == 1 ? true : false}
renderItem={({ item }) =>
<LocationInfo
bottom={results[results.length - 1].id == item.id ? insets.bottom : 0}
result={item}
wait={waitState[item.id]}
bsIndex={bottomSheetIndex}
/>
}
/>
const LocationInfo = ({ bottom, result, wait, bsIndex }) => {
return (
<View style={[styles.container, { paddingBottom: bottom }]}>
...
for insets, see react-native-safe-area-context.

Answer 6

Remove flex:1 from the FlatList and leave only the parent View.

Answer 7

Add flex: 1 to child into renderItem
<View style={{ height: `93%` }}>
<FlatList
contentContainerStyle={{ minHeight: `100%` }}
scrollEnabled={true}
...props
renderItem={({item}) => (
<View style={{ flex: 1 }}>
...
</View>
)}

Answer 8

I had the same problem. What I did was to provide a marginBottom to the parent view of the FlatList with size that is equivalent (or a little larger) than the size of the rendered item .
<View style={{marginBottom: HEIGHT_OF_CELL + 60, flexGrow:1}}>
<FlatList
keyExtractor={(item, index) => index.toString()}
data={posts}
renderItem={renderItem}
/>
</View>

Answer 9

I method I used to resolve this is by setting the parent view to the FlatList's background color to a visible color(e.g red). Then adjust the margin bottom for that view so that it is large enough for all the contents in the FlatList to be viewed.
In my case the parent view was wrapped in another view which I could not give the flex: 1 style to.

Answer 10

use dimensions for parent view and set height as given:
const screenHeight = Dimensions.get('window').height - 100
<View style={{...styles.container,height:screenHeight}}>
....All child components
</View>

Answer 11

adding flex:1 to my render item worked for me
<FlatList
data={data}
renderItem={({ item }) => (
<ListItem
onPress={() => console.log('ok')}
bottomDivider
rightTitle={
<Divider style={{ marginBottom: 4, backgroundColor: item.status, width: '50%', height: '11%', borderRadius: 10 }} />
}
titleProps={{ numberOfLines: 1 }}
rightSubtitle={item.date}
rightTitleStyle={{ fontFamily: 'poppins' }}
rightSubtitleStyle={{ fontFamily: 'poppins' }}
titleStyle={{ fontFamily: 'poppins' }}
subtitleStyle={{ fontFamily: 'poppins' }}
title={item.device}
subtitle={item.type}
leftAvatar={{ source: item.icon, rounded: false }}
**style={{ flex: 1 }}**
/>
)}
keyExtractor={item => item._id}
ListHeaderComponent={renderHeader}
ListFooterComponent={renderFooter}
onEndReached={handleLoadMore}
onEndReachedThreshold={0.2}
/>
