Glitchy iOS search bar when using Section List

[KenanBouvier]

Description

Hi, I wanted to report this issue I am having regarding a glitchy iOS search bar.

Please see the video below for a demonstration of the glitch.

Similarly, you can see the search bar glitch with these images:

Whereas it should be as such:

Overview

Ideal app desired functionality: have sticky headers (located correctly), search bar (Normal behaviour) and (Non-glitchy) pull to refresh.

Here is an overview of the problem:

• To get the sticky headers to work, we have to use SafeAreaView  
• By using SafeAreaView, this results in glitchy pull to refresh 
• To fix the glitchy pull to refresh, we set the headerTransparent as true (To fix another trigger of glitchy refresh) and set the marginTop to be the header height. This is so that the content is pushed down accordingly, allowing for the sticky headers to "stick" in the right location (instead of up top and behind the header)
• This results in a glitch with the search input, in that it doesn't expand and collapse correctly        
• I believe the reason why the search input now doesn't behave correctly is due to the margin top.

About the search bar glitch, normal behaviour consists of "locking" in and out of view depending on if most of the search bar is show. When you pull to refresh (repository linked below), it initially shows the full search bar. However, it does not keep this behaviour when we scroll down then back up.

Refresh glitch replication

To demonstrate the glitchy pull to refresh, you can set the headerTransparent property to false within the useLayoutEffect hook in the App.tsx file. And if that is enabled then you can comment out the marginTop in the first View component as that is pushing the content the same as the headerHeight (for when it is transparent). E.g.

      headerTransparent: true, // set to false here to demonstrate glitchy activity indicator/pull to refresh.

And

     marginTop: headerHeight,  // Comment out if headerTransparent is false. I.e testing out glitchy refresh control.

Can you let me know if I'm doing anything wrong or advice with this issue?

Thanks!

I am looking into it now. I've tested the provided repro and allowed myself to simplify it a little. I found two separate problems:

1. the refresh spinner flickers when headerTransparent is set to false in screen options. Maybe related to this issue: https://github.com/react-navigation/react-navigation/issues/11818

Reproducer

``` import React from 'react'; import { Text, RefreshControl, SectionList } from 'react-native'; import { NavigationContainer } from '@react-navigation/native'; import { createNativeStackNavigator } from '@react-navigation/native-stack'; const sectionData = [ { title: 'Main dishes', data: ['Pizza', 'Burger', 'Risotto'], }, { title: 'Sides', data: ['French Fries', 'Onion Rings', 'Fried Shrimps'], }, { title: 'Drinks', data: ['Water', 'Coke', 'Beer'], }, { title: 'Desserts', data: ['Cheese Cake', 'Ice Cream'], }, { title: 'Main dishes', data: ['Pizza', 'Burger', 'Risotto'], }, { title: 'Sides', data: ['French Fries', 'Onion Rings', 'Fried Shrimps'], }, { title: 'Drinks', data: ['Water', 'Coke', 'Beer'], }, { title: 'Desserts', data: ['Cheese Cake', 'Ice Cream'], }, { title: 'Main dishes', data: ['Pizza', 'Burger', 'Risotto'], }, { title: 'Sides', data: ['French Fries', 'Onion Rings', 'Fried Shrimps'], }, { title: 'Drinks', data: ['Water', 'Coke', 'Beer'], }, { title: 'Desserts', data: ['Cheese Cake', 'Ice Cream'], }, { title: 'Main dishes', data: ['Pizza', 'Burger', 'Risotto'], }, { title: 'Sides', data: ['French Fries', 'Onion Rings', 'Fried Shrimps'], }, { title: 'Drinks', data: ['Water', 'Coke', 'Beer'], }, { title: 'Desserts', data: ['Cheese Cake', 'Ice Cream'], }, { title: 'Main dishes', data: ['Pizza', 'Burger', 'Risotto'], }, { title: 'Sides', data: ['French Fries', 'Onion Rings', 'Fried Shrimps'], }, { title: 'Drinks', data: ['Water', 'Coke', 'Beer'], }, { title: 'Desserts', data: ['Cheese Cake', 'Ice Cream'], }, { title: 'Main dishes', data: ['Pizza', 'Burger', 'Risotto'], }, { title: 'Sides', data: ['French Fries', 'Onion Rings', 'Fried Shrimps'], }, { title: 'Drinks', data: ['Water', 'Coke', 'Beer'], }, { title: 'Desserts', data: ['Cheese Cake', 'Ice Cream'], }, { title: 'Main dishes', data: ['Pizza', 'Burger', 'Risotto'], }, { title: 'Sides', data: ['French Fries', 'Onion Rings', 'Fried Shrimps'], }, { title: 'Drinks', data: ['Water', 'Coke', 'Beer'], }, { title: 'Desserts', data: ['Cheese Cake', 'Ice Cream'], }, { title: 'Main dishes', data: ['Pizza', 'Burger', 'Risotto'], }, { title: 'Sides', data: ['French Fries', 'Onion Rings', 'Fried Shrimps'], }, { title: 'Drinks', data: ['Water', 'Coke', 'Beer'], }, { title: 'Desserts', data: ['Cheese Cake', 'Ice Cream'], }, { title: 'Main dishes', data: ['Pizza', 'Burger', 'Risotto'], }, { title: 'Sides', data: ['French Fries', 'Onion Rings', 'Fried Shrimps'], }, { title: 'Drinks', data: ['Water', 'Coke', 'Beer'], }, { title: 'Desserts', data: ['Cheese Cake', 'Ice Cream'], }, { title: 'Main dishes', data: ['Pizza', 'Burger', 'Risotto'], }, { title: 'Sides', data: ['French Fries', 'Onion Rings', 'Fried Shrimps'], }, { title: 'Drinks', data: ['Water', 'Coke', 'Beer'], }, { title: 'Desserts', data: ['Cheese Cake', 'Ice Cream'], }, { title: 'Main dishes', data: ['Pizza', 'Burger', 'Risotto'], }, { title: 'Sides', data: ['French Fries', 'Onion Rings', 'Fried Shrimps'], }, { title: 'Drinks', data: ['Water', 'Coke', 'Beer'], }, { title: 'Desserts', data: ['Cheese Cake', 'Ice Cream'], }, { title: 'Main dishes', data: ['Pizza', 'Burger', 'Risotto'], }, { title: 'Sides', data: ['French Fries', 'Onion Rings', 'Fried Shrimps'], }, { title: 'Drinks', data: ['Water', 'Coke', 'Beer'], }, { title: 'Desserts', data: ['Cheese Cake', 'Ice Cream'], }, ]; function SearchScreen() { const [refreshing, setRefreshing] = React.useState(false); const onRefresh = React.useCallback(() => { setRefreshing(true); setTimeout(() => { setRefreshing(false); }, 500); }, []); return ( item + index} refreshControl={ } renderItem={({ item }) => {item}} renderSectionHeader={({ section: { title } }) => ( {title} )} /> ); } const Stack = createNativeStackNavigator(); export default function App() { return ( ); } ```

2. the header and the searchbar do not "snap" into fully expanded / folded state when the screen content (SectionList in the example above) has custom marginTop style set to a value within certain range (reproducible with headerHeight).

``` import React from 'react'; import { Text, RefreshControl, SectionList } from 'react-native'; import { NavigationContainer } from '@react-navigation/native'; import { createNativeStackNavigator } from '@react-navigation/native-stack'; import { useHeaderHeight } from '@react-navigation/elements'; const sectionData = [ { title: 'Main dishes', data: ['Pizza', 'Burger', 'Risotto'], }, { title: 'Sides', data: ['French Fries', 'Onion Rings', 'Fried Shrimps'], }, { title: 'Drinks', data: ['Water', 'Coke', 'Beer'], }, { title: 'Desserts', data: ['Cheese Cake', 'Ice Cream'], }, { title: 'Main dishes', data: ['Pizza', 'Burger', 'Risotto'], }, { title: 'Sides', data: ['French Fries', 'Onion Rings', 'Fried Shrimps'], }, { title: 'Drinks', data: ['Water', 'Coke', 'Beer'], }, { title: 'Desserts', data: ['Cheese Cake', 'Ice Cream'], }, { title: 'Main dishes', data: ['Pizza', 'Burger', 'Risotto'], }, { title: 'Sides', data: ['French Fries', 'Onion Rings', 'Fried Shrimps'], }, { title: 'Drinks', data: ['Water', 'Coke', 'Beer'], }, { title: 'Desserts', data: ['Cheese Cake', 'Ice Cream'], }, { title: 'Main dishes', data: ['Pizza', 'Burger', 'Risotto'], }, { title: 'Sides', data: ['French Fries', 'Onion Rings', 'Fried Shrimps'], }, { title: 'Drinks', data: ['Water', 'Coke', 'Beer'], }, { title: 'Desserts', data: ['Cheese Cake', 'Ice Cream'], }, { title: 'Main dishes', data: ['Pizza', 'Burger', 'Risotto'], }, { title: 'Sides', data: ['French Fries', 'Onion Rings', 'Fried Shrimps'], }, { title: 'Drinks', data: ['Water', 'Coke', 'Beer'], }, { title: 'Desserts', data: ['Cheese Cake', 'Ice Cream'], }, { title: 'Main dishes', data: ['Pizza', 'Burger', 'Risotto'], }, { title: 'Sides', data: ['French Fries', 'Onion Rings', 'Fried Shrimps'], }, { title: 'Drinks', data: ['Water', 'Coke', 'Beer'], }, { title: 'Desserts', data: ['Cheese Cake', 'Ice Cream'], }, { title: 'Main dishes', data: ['Pizza', 'Burger', 'Risotto'], }, { title: 'Sides', data: ['French Fries', 'Onion Rings', 'Fried Shrimps'], }, { title: 'Drinks', data: ['Water', 'Coke', 'Beer'], }, { title: 'Desserts', data: ['Cheese Cake', 'Ice Cream'], }, { title: 'Main dishes', data: ['Pizza', 'Burger', 'Risotto'], }, { title: 'Sides', data: ['French Fries', 'Onion Rings', 'Fried Shrimps'], }, { title: 'Drinks', data: ['Water', 'Coke', 'Beer'], }, { title: 'Desserts', data: ['Cheese Cake', 'Ice Cream'], }, { title: 'Main dishes', data: ['Pizza', 'Burger', 'Risotto'], }, { title: 'Sides', data: ['French Fries', 'Onion Rings', 'Fried Shrimps'], }, { title: 'Drinks', data: ['Water', 'Coke', 'Beer'], }, { title: 'Desserts', data: ['Cheese Cake', 'Ice Cream'], }, { title: 'Main dishes', data: ['Pizza', 'Burger', 'Risotto'], }, { title: 'Sides', data: ['French Fries', 'Onion Rings', 'Fried Shrimps'], }, { title: 'Drinks', data: ['Water', 'Coke', 'Beer'], }, { title: 'Desserts', data: ['Cheese Cake', 'Ice Cream'], }, { title: 'Main dishes', data: ['Pizza', 'Burger', 'Risotto'], }, { title: 'Sides', data: ['French Fries', 'Onion Rings', 'Fried Shrimps'], }, { title: 'Drinks', data: ['Water', 'Coke', 'Beer'], }, { title: 'Desserts', data: ['Cheese Cake', 'Ice Cream'], }, { title: 'Main dishes', data: ['Pizza', 'Burger', 'Risotto'], }, { title: 'Sides', data: ['French Fries', 'Onion Rings', 'Fried Shrimps'], }, { title: 'Drinks', data: ['Water', 'Coke', 'Beer'], }, { title: 'Desserts', data: ['Cheese Cake', 'Ice Cream'], }, ]; function SearchScreen() { const [refreshing, setRefreshing] = React.useState(false); const headerHeight = useHeaderHeight(); const onRefresh = React.useCallback(() => { setRefreshing(true); setTimeout(() => { setRefreshing(false); }, 500); }, []); return ( item + index} refreshControl={ } renderItem={({ item }) => {item}} renderSectionHeader={({ section: { title } }) => ( {title} )} /> ); } const Stack = createNativeStackNavigator(); export default function App() { return ( ); } ```

I think that headerTransparent: false should be used in this kind of situation. The second problem is caused by a hacky workaround for the first one.

Btw. It's related to a known issue: https://github.com/software-mansion/react-native-screens/blob/5301d3f226a80ec7983e49209e8cee505d3a2ae7/README.md?plain=1#L208
