FlatList is killing the performance of your app

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

Does that mean its faster than recyclerlistview

I think you are using the flatlist wrong, the renderItem should be a memoized value, you can use useCallback for that and then pass the function to the flatlist renderItem={renderItem} . If you are not doing that the renderItem variable receives a new function every app rerender, and this can cause unnecerasy rerendering of the items in the list.

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

Very helpful 👍👍

thanks!

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

You are a beauty dude

Thanks! it will be very useful for my project.

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

"CommandError: Required property 'android.package' is not found in the project app.json. This is required to open the app."

Vadim sorry ur front end skills are horrendous

hey can you create video rn for new architecture?

hello sir can you please make video on voximplant message Am really stuck so please help me

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?

Great 👍

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

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.

very informative 🤘👍

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?

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!

I already use it

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

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

❤️

Vooooo

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