I have a screen with WebView (react-native-webview) which has scrollable content. If user continues scrolling after reaching the end of WebView, I want to take user to a different screen with a swipe up animation. With WebView's onScroll function property, I am able to determine if the user has reached end of content or not. But I am not able to take user to a different screen with an animation effect.
Since WebView acts different for android and ios platform (you can continue scrolling even after reaching end of content on ios), I had to use PanGestureHandler to identify if the user is performing swipe up action after reaching end of web content. But when I manually try to navigate user to a different screen, I am unable to create swipe up effect similar to one in GIF below.
I am using react-navigation v5 in my app.
I have already tried using react-native-swiper. It does not work well in Android because it internally uses Scrollable and WebView stop scrolling inside a Scrollable component.
I am using custom HTML content here, so replacing WebView is not really a choice. Is there a way to utilize Stack Navigator to create such an effect?
Thank you.

I am using React Native's FlatList component with pagination. I want to execute a callback with the destination page as a parameter whenever the user releases on scroll.
onScroll fires pre-maturely and switches pages before the users releases the screen.
onScrollDragEnd doesn't correctly give you the destination page unless you drag your finger at least half way across the screen (eg doesn't work if you do a quick swipe).
onMomentScrollEnd doesn't get fired until the display stops moving, which may not get fired if the user is constantly swiping.
Is there some sort of middle ground to achieve this functionality?
I want to have a scrollable (with snap points) react native navigation stack screen(presentation: "modal") in my app. I don't want anything like "react-native-modal" library or official Modal from react native library. I want an actual screen with modal behaviour and I can achieve that with presentation: "modal" property but I want it to have snap points. Perfect example would be the iOS fitness app.
So this is the screen when you initially press upload button. As you can see it takes maybe 40% - 50% height of the screen
If you scroll down height expands and it acts as ordinary screen with presentation: "modal"
And lastly if you scroll back up it springs back to its original position and it acts as a modal(no gap at the top of the screen as in second image)
That is the behaviour I am looking for.
If it is possible I would like to get similar behaviour on android as well.
I tried to implement that behaviour with "react-native-modal" and official Modal from "react-native" components but I want to have it as a separate screen. I also want it to feel "native like" and with these stuff it doesn't feel that way.
You may try this library react-native-simple-bottom-sheet
I use transparentModal for open a modal in react native.
Stack Group 1: Contains App Screens
Stack Group 2: using transparentModal for handling modal
The modal only occupies 2/3 of screen, and there are some button on the top which should be clickable. However, we cannot press these buttons.
Please take a look at the image below
If you have any idea, please let me know.
Thank you in advance!
Transparent modals are just another screen (s. docs). Meaning that the background's screen is set to transparent, but the underlying screen is not pressable.
A possible solution is to move your buttons in a custom header component for your transparentModal screen (s. docs).
Alternatively (but in your case that's seems not the right way to go), you can set cardOverlayEnabled: true to make the screen close if you tap on the background of your transparent modal screen.
Bad news is that we cannot do it using react-navigation
Please take a look at this link
I'm looking for a solution, if possible a library or a custom component, for React Native, without Expo.
I need to create a video frame that is movable in the screen, up and down, and cover the content. I also need to make it possible to click on the content behind it.
Another difficulty is that I need it to stay up on all screens during navigation.
I first tried to use reanimated-bottom-sheet with some increments, but the content behind the bottom is not clickable. Also, to make it available on all screens I needed to put in at the same level as React Navigation's BottomTabNavigator and it covers the tab bar too even with a zIndex.
I also tried to use modals, but I'm relatively new to React Native and couldn't find how to make the background touchable as well as making it movable.
I guess I need to make a view with absolute positionning and learn Reanimated, unless you have a simpler idea?
Thanks
I am developing my first React Native + Redux app. In my app I want to develop something similar to the friends requests slider of facebook:
There is a slider (left/right) where you can see the current content in a box and a little bit of the next and preview item. When swiping up or tap the content should be come to "full screen". Swiping left or right is disabled in full screen.
Only the current and maybe the two next and the two previous slides should be loaded but I think thanks to redux this is not a big deal.
Which components should I use for this?
A simple way to approach this might be to use a library like react-native-swiper for the swiping component and then use LayoutAnimation to animate the subview into the full screen view, taking care to remove the name in the header/etc.
