FlatList is killing the performance of your app

Рет қаралды 30,135

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?

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!

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?

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 Жыл бұрын

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.
