when giving Flatlist data large array and using multiple ShimmerPlaceHolder then this error occur.

If array length is small( Flatlist data) or less number of ShimmerPlaceHolder used then I doesn't get this warning

<FlatList showsVerticalScrollIndicator={false} // keyExtractor={item => item.id} contentContainerStyle={{paddingBottom: 30}} style={{paddingHorizontal: 16}} data={[...Array(10).keys()]} // Generate an array of 10 items ItemSeparatorComponent={() => <View style={{height: 14}} />} renderItem={({index}) => ( <Button key={index} style={s.list_container}> <ShimmerPlaceHolder style={{ width: 60, height: 60, marginRight: 16, borderRadius: width * 0.25, }} LinearGradient={LinearGradient} /> <View style={{flex: 1, rowGap: 16}}> <ShimmerPlaceHolder style={{width: '90%'}} LinearGradient={LinearGradient} /> <ShimmerPlaceHolder style={{width: '90%'}} LinearGradient={LinearGradient} /> </View> <View style={s.btn_container}> <ShimmerPlaceHolder LinearGradient={LinearGradient} style={s.btn_shimmer} /> <ShimmerPlaceHolder LinearGradient={LinearGradient} style={s.btn_shimmer} /> <ShimmerPlaceHolder LinearGradient={LinearGradient} style={s.btn_shimmer} /> </View> </Button> )} />

Okay thanks. Does this make application slow during initial rendering. I have lots of item on mainscreen which use shimmer effect
