In this fantastic video, made by William Candillon from http://start-react-native.dev he shows how to make this off-screen menu. Code can be found here: https://github.com/wcandillon/can-it-be-done-in-react-native/tree/master/the-10-min/src/Menu
My question is, would it be possible to create a function that can close the profile screen programmatically instead of the user swiping on the profile card.
Preferably, it closes with the animation, but a plan B could be to just gracefully return the state of the animation back to the starting point. A general function that can fake a swipe would be awesome.
Thanks in advance!

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 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 would like to create a carousel that scrolls automatically until the user scrolls / touches the ScrollView itself.
The auto-scrolling itself works fine with using scrollView.scrollTo but how could I detect if the user is interacting with the ScrollView? I took a look at the onScroll event but this does not seem to distinct between a user generated event and an event that was generated by calling scrollTo.
Also I'd like to know if it is possible to get the current scroll position from the ScrollView directly instead of reading it everytime from the onScroll event.
I'm very thankful for any tips and suggestions.
By digging into ScrollView's source code you can notice a few undocumented callbacks that will help you achieve what you're after, namely onTouchStart and onTouchEnd. These two callbacks are triggered only when user interacts with the ScrollView and not when you scroll programmatically.
You will probably want to clear your auto-scroll interval on onTouchStart and restart it after a delay on onTouchEnd.
Regarding your next question, the answer is no. As far as I know, no getter is currently exposed to retrieve the current scroll position. Therefore, you need to rely on the event passed to onScroll, retrieve event.nativeEvent.contentOffset['x' or 'y'], and store it in your component's state.
Note that if you're doing some heavy animations that need to follow scroll position closely (e.g. animated header or parallax image), it would be a good idea to use the native driver for Animated.event. You can learn more about it on React Native's blog.
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.
I am developing this app for ipad and ios9 and at some point the user will click on a button to watch a video. But I wouldn't want the user to just see it in the split view size he's currently on (like 1/3rd or 14th) instead I would like the app to close the other open app and for it to take over the entire screen.
Does anyone know if that's possible? Thanks.
By-default, the video always get played in full-screen mode. When video playing is finished, the player gets dismissed and you will see your screen (from where you played the video). In your case, in split view controller.
Do let me know if you need further details.
