Advanced React Native FlatList animations at 60fps with Animated API

[@CatalinMironDev]

I received a lot of comments that this is not visible on Android devices. Here's the fix for it: snack.expo.io/@catalinmiron/react-native-movie-2.0-carousel-for-android. Thanks a ton!

[@zare775]

Hi, in your example you use useNativeDriver: false. It is too slow on my device. Do you have any solution with useNativeDriver: true for android ?

[@pixelwizardai]

I have managed to try and works on android, don't know the implication but I make the { useNativeDriver:false} in Animate.Flatlist} and follow the above code link, and made some changes as the input range is const inputRange = [ (index - 1.5) * ITEM_SIZE, (index - 1) * ITEM_SIZE ] and const translateX = scrollX.interpolate({ inputRange, outputRange:[0, width], extrapolate:'clamp' })

[@jeanwona2689]

Hello dear, thank you for all the work you have done. But for fix the flatlist active component in the middle of screen, you can use another smooth way. You can create a Empty component that will contain an empty view which must have SPACER_ITEM_SIZE as width value. Then put this component as listHeaderComponent and listFooterComponent for your flatlist. That is all. Sorry for my bad english guys. Please, have you a store of paid react-native advanced animations courses for people who want it?

[@sykn3z]

Thanks keep making videos like this! :D

[@CatalinMironDev]

Thanks Snaaapzter! ✌️

[@naibtahmazli6384]

instead of using if statement to check and add view u can directly add view to before an after flatlist using listHeaderComponent and listFooterComponent

The app was launched in the AppStore but Dribbble cut the whole API I think that knowing JavaScript and a little bit of CSS can help you out, knowing React is definitely a plus because will make your transition smoother. Yes, you can write cross-platform solutions in React/React Native I’m working at Skype which is a cross-platform application built with React and React Native. Thanks 🙏

It seems that the problem is with MaskedView maskElement, it is too expensive to recalculate something that's moving so I opted-in for using *width* animation and remove the MaskedView completely since it's not performant of Android.

Hey Catalin! Firstly, thanks for the tutorials, I've seen a lot of them already. I have a doubt, I'm trying to animate the FlatList using the Reanimated v2, but I'm getting frame drops, which is making me start using the AnimatedAPI. Do you know how can I avoid frame drops on FlatLists using Reanimated v2? Anyone who sees this comment and is experiencing the same problem, know how to fix it?

[@MerciBro]

Had the same problem yesterday. I solved it by building some limitor algorithms for the data being passed into the list. What's weird is that if you map the same data in a scrollview, you dont get the frame rate drop.
