FlatList is killing the performance of your app

Lists are one of the most common components in React Native, but the FlatList has always been kinda slow and buggy when dealing with large lists. FlashList comes to solve this problem as a Fast & Performant React Native List.
In this video, we will compare the performance of the FlatList vs FlashList and see if it indeed improves the performance by x5 as it claims.

It's a cool video. Can you do more videos for optimize RN apps?

[@Muzly]

I second this suggestion.

[@DevRSC]

Same here

second

[@JesusMendoza-ky7et]

Just tested this on our app and it’s so much better! We have components in a Flatlist with remote images and where the standard FlatList mounts all of them triggering the requests, FlashList actually mounts components as you scroll so almost no network requests on mount! Then I could see the network requests come in as I scroll all with essentially the same API. Great video!

[@mystik5551]

Awesome, been searching for something better. Will definitely try it

[@betelgeus2029]

Thanks! it will be very useful for my project.

[@nguyenhuynh6769]

Great! I really like this video. It's useful for beginer as me.

[@surbhitrao]

Can you also compare recyclerlistview vs FlashList? That will be an intresting watch

[@rudeadyet1992]

Thanks for the Cool video! BTW the new architecture would drastically improve such issues. Have you guys thought of experimenting the new RN "Bridgeless" architecture in the near future?

[@anum2471]

very informative 🤘👍

[@davidlintin]

Hey nice video. However your thumbnail shows a SectionList. Is there a FlashSectionList?

[@gamingwithsanjay5748]

hey I have made reavt native with firestore that is too slow can you tell what to use to make it fast?

[@ytexchanger3093]

Thanks for the video bro... but i have a really important question. Is there anyway we can display react native/component over other apps just like Facebook messenger?

[@osmtechbox2658]

Yes I did this on android but you need to use native module and write code on native side. I did code for floating view in java which will be visible outside the react native app.

My application Uber clone in react cli crashed. After installing build gradle version 6.5 and plugin version 4.1.0. And build tools 29.0. Please help me.

[@visheshgupta4990]

[@maxaquilino7264]

Very impressive video! I'm using Animated.FlatList from Animated react-native library. How can I implement FlashList in that scenario?

[@thiagosilvaloopes]

Check out the FlashList documentation, they have a section about the implementation of react native reanimated with it

[@hungtran7681]

I tried and got this error: Invariant Violation: requireNativeComponent: "AutoLayoutView" was not found in the UIManager.How can i fix that? thanks

[@mycraplife]

Did you find a solution?

[@edena276]

Is that component stable enough to use on all sort of devices either new or old and iOS or Android ?

[@chetanbawankule2035]

This is important questions

[@notjustdev]

It has been well tested internally by Shopify team before making it public. Now, the library is stable for production

This is great! but fails to build on Android when using RN 0.70.8

[@lingarajsahoo3583]

❤️

[@MrRahulmalik]

Tried it for about 100+ items. Components are a lil complex with nesting but scrolling is still poor and visible blank areas in android

[@shubhamrathore5825]

Except these issues do you feel the worth of using this ...

[@MrRahulmalik]

@@shubhamrathore5825 if you have a pretty simple item layout and don't need the missing features then yes it is better than normal Flatlist, keep in mind it only works when you apply all the optimizations that they specify in order to be more efficient

[@shubhamrathore5825]

@@MrRahulmalik Thanks for this information!

[@valkyrieqp]

we tried to make the switch but the blank areas were a dealbreaker

[@MrRahulmalik]

@@valkyrieqp I solved it by exposing the native Android list to RN and using it, it's fast and smooth and no blank areas!

Does that mean its faster than recyclerlistview

I know people need to touch the 10 min mark, but when padding the content is so shameless, it feels like creator does not respect his viewers time. Like first 3:30 of this video can be completely skipped

Not doing it intentionally. Thanks for feedback
