I use a Bottom Tab Navigator with several different stacks in my React Native app. I have created a screen that opens like a modal using this in the screen options:
{ presentation: "modal" }
On iOS, phones with no physical home button (e.g. iPhone 12) get a strange unwanted bottom radius when the screen has been navigated to:
When the screen is being dismissed, the border radius gets even larger for a couple of seconds until it disappears completely:
I've tried changing the border radius on the screen's view but no luck. How do I get rid of this unwanted border radius? Thanks.

I'm making an app with react native, expo, bottom-tab-bar navigation package, and expo-screen-orientation package.
The app is for reading some text that is inside some View elements in the middle of the screen, and is controlled with the bottom tab bar.
When I rotate the phone, and change the screen orientation (portrait-landscape), it kind of messes with the UI layout.
What I'd like to achieve, is to only have the View element that contains the readable text to rotate when the phone changes orientation, but the rest of the app (The bottom tab bar, background, buttons, etc.) to stay in the 'portrait' orientation.
What I've tried so far is this:
I've tried to lock the screen to portrait with
ScreenOrientation.lockAsync(ScreenOrientation.OrientationLock.PORTRAIT);
and then listening to orientation changes with eventListeners, Dimentions, useWindowDimentions, and expo-screen-orientation's ScreenOrientation.AddOrientationChangeListener(Listener),
and then maybe rotating the View element manually.
But if the screen is locked and not rotated, the change is not detected.
I've looked but couldn't find an answer.
I need a way to create a tab bar that will vertically bump up the upper text and stick to the top of the page.
I currently am using createMaterialTopTabNavigator and it sits in the vertical center of the screen. I would like such that when a person scrolls on the subpages from the tab navigator for the whole page to scroll with it until the topTabNavigator sticks to the top of the screen.
I am currently using React Native + Expo.
I am open to different options as well. I have tried using a panel and embedding the tab bar in that but it caused weird scrolling issues on Android devices.
Thanks!
So I have a react-native app which is using react-native-navigation.
Whenever I click a card in my app, it pushes me the card screen.
What I want to achieve is the following: when swiping down from that screen, as you swipe down the screen gets smaller and the other one is in the background, but I haven't found anything that can help me with that, any packages? Also, I'd have to pop the current screen to have the other one the background, but if I pop it, the current screen can't stay and get smaller as i swipe down.
So basically I need to animate a component pop.
If you haven't figured it out yet, you could show the card screen as an overlay or modal and add a swipe-down gesture to the Container component of the screen and when it reaches the bottom, you could dismissOverlay or dismissModal with no animation.
I am using native base tabs to display scrollable tab bars in react-native
I had 4 tabs and the content in each render item tab changes, so the length of the tab bar content changes. how can I adjust the height of the scroll view based on content in tabview. it should not scroll when content is less. it leaves blank space below when content is less.
when content in tab bar render item is more than the screen height it scrolls.
when content in tab bar render item is less than the screen height it should not scroll.
even if the content in the 2nd tab is less it scrolls based on height of 1st tab content height.
It should not scroll if the content on in tab render item is less.It should scroll based on the content in tab view
it's the sole reason why i left native-base because of the issue. It's and open issue with native base and they havent resolved it yet. The problem is that i had 3 tabs and three scrollViews had different height. so it takes the longest height and when we go to any other tab , it leaves blank space.
this is the link to the open issue in github native base tabs . Do check it out if you can find any resolution for it. I couldnt find it so ive switched to
react native tab view . .This is a better library for tabs and coz of the issue in native abse. i switched to it.
Hope it helps. Feel free for doubts
When app bar is present, the height of the app bar affects the content on the rest of the page.
For example, if the app bar has a Height of about 25px when ClosedDisplayMode="Minimal", the rest of the content on the page (rootGrid) would have its actual height of Screen Height - 25px. So the app bar is not overlay on page content.
This is visible especially when the content is VerticalAlignment="Center" or Bottom.
Is there any way to avoid this? Something like a ZIndex on the AppBar so that it is displayed over the page content and not trimming it on the bottom side of the screen.
It is possible to tell the renderer that the whole "window" should be used when rendering and not just the visible part. By calling Windows.UI.ViewManagement.ApplicationView.GetForCurrentView().SetDesiredBoundsMode(ApplicationViewBoundsMode.UseCoreWindow) the renderer will include the areas beneath the chrome of the window (ie the system tray on top of the screen and the app bar at the bottom). The chrome will always be on top of whatever is rendered from xaml.
ApplicationView is documented here.
If you don't want the system tray on the top of the screen to overlap the content, you'll have to compensate with a margin on the root container of your visible xaml.
