Just wanted to hop back in and say thanks. I was just watching this video the other week, and today, I ran into a situation where I had to add a static element to my scrollview and I suddenly remembered your neat little trick of 'cancelling out' the translation during scroll. Worked like a charm, in less than a minute. Absolute lifesaver trick I would never, ever have come up with if it wasn't for your video. Keep 'm coming!

[@tamishkhurana8784]

Just wow, you motivated me more for animations after this, thanks🙏

[@PVideos10]

Please do more of these tutorials with the animated api.

[@wcandillon]

Message received. Will try to showcase other examples where it might make sense.

[@MrLucasEss]

The content on this channel is pure gold!! The only thing though is that you don't give a clear explanation on why every decision was made and what each value actually means. But then it's not on you to explain every concept, that's were being an autodidact comes handy. Either way, love the content

so jhonny sins is also a developer i am impressed

AHAHAHAHAHAHAHA

[@yaltharullist9181]

I already fell in love with your accent

[@mrst8086]

Looks awesome, thanks for your example!

[@lucaslaurens4208]

Really cool and fun to watch video. It's a great animation to copy. Thank you !!

[@_maksime]

Really interesting as usual ! Congrats

[@droidmakk4968]

It's the end of June 2020 already and I'm all gearing up for React Native animations and transitions 😇

[@loki6841]

Wow can't wait to try it out

[@oscar_cornejo]

Will there be a new series of these videos or more examples, but with Reanimated 2?

[@christianparra3162]

Great as always! back to the basics, will be great something like this with the "hide/show header on scroll" on android is kinda tricky and almost all examples are outdated

[@wcandillon]

That's a great idea.

[@weligamage1]

Thank you. keep up your good work

[@trigun539]

Great video, thank you!

[@WholeNewLevel2018]

Awesome video! May I ask you from where I can get such a beautiful card background style. Appreciated It if you can tell me how you made them or what this kind of design called.

[@hyacinthehamon]

Amazing as always :)

[@waroulolz]

Line 35 should be "outputRange: [0, -index * (CARD_HEIGHT + 2 * MARGIN)]" right ? With a bigger list, margins add up and you would see cards disappearing before hitting the top of the screen

[@lawrencelau3771]

So adorable french style english

[@Jorsfel]

Excellent tutorial, thank you! Also love your accent haha, you sound more French than Swiss to me but I'm Australian so am hardly qualified to tell the difference. :p

[@armaghanasghar2911]

Great observation. A large part of Beautiful Switzerland speaks French (~30%). They also speak German (~60%). William was likely raised in French speaking part of the region. Cheers!

[@wolfromkev]

If anyone is following along to add this to their own project, a good way to get the exact height of your element is to use the onLayout props, which will automatically calculate the height of your component. const [itemHeight, setItemHeight] = useState(0); const onLayout = (e) => { setItemHeight(e.nativeEvent.layout.height); }; ...content

[@wolfromkev]

Followup: Ensure to add the margin to this value if you have one on your component. const [itemHeight, setItemHeight] = useState(0); .... ... .. . { setItemHeight(e.nativeEvent.layout.height + MARGIN); }} style={[ styles.listing, { opacity, transform: [{ translateY }, { scale }] }, ]} >

[@danielnegrisoli]

Great tutorial!

[@akhiljain5214]

Can you update and explain the same animation for a two column flat list ?

[@joelsidy]

really cool !!! Thank you

[@linbook955]

hi，what recording software were you using? your image on the bottom left，how did you make it? thank you so much

[@makisetakashi]

I love the simplest one

[@deepakpanwar9717]

Nice tutorial mate, and please tell us which them you're using for VsCode, that's a delicious purple color theme. I want the same.

Hello, I need a flat list with optimization for the contact list. could you create a video for this? I didn't find a single thing on this. I have tried all the given solutions on the internet and perform all the optimization.

[@fam8937]

hello Sir. There is one problem with animations. if I have a list of dynamic items it depends on paggination, then the animation is not good.Initially it's working fine but after some item it somewhat lower than the top. experience some blank space on the top of the screen.

[@richardpatove4587]

where is the first lesson for animations is there any zero to hero playlist

[@SohaibKarim]

amazing explanation and accent 🙂 Can you do a tutorial on scratch card animation please ? It can help us with gesture + animation both.

[@shortquts]

Idea for another tutorial: Pinterests Masonry Image Layout

[@shristysinha3114]

hello sir, i have two doubts , ,instead of typescript i am using js, and since u have used in walletCard.tsx -> y as Animated.Value in interface and i have taken the y state as props from wallet.tsx -> like this -> const[y, setY ] =useState(new Animated.Value(0)); and using this as as prop in walletCardd.tsx and the other doubt is : how i should used the interface 'index: number' in my interpolate -> inputRange: [0, 0.00001 + index * CARD_HEIGHT], i have taken 'index' as prop from previous component. Please help me

[@mohammedalshafie8226]

im trying to do this with a horizintal flatlist but things got missed up can anyone help ?

[@guillaumeRean]

Great great great :D I'm going to implement that immediatly (in left to right..) !! But do you think it can work with the snapToInterval prop of the scrollview ?

[@guillaumeRean]

Yes it can (he said it in the video) but i've also implemented it.

[@yaroslav9586]

You create library react native reanimated?

[@rukmanaland]

if the Flatlist is horizontal we can simply change y to x?

[@kevinthomas4777]

You are just amazing ❤️❤️❤️❤️

[@dejijames4358]

Hi Wonderful Video. Is there a .js version of this ? Or must it be .tsx

[@rodrigososa5281]

how to animate remove item? After remove item, the item below it should slide slowly up? can you make video on that ?

[@wcandillon]

I have a video on that at kzbin.info/www/bejne/Z5WbkpKEj56fZ6c

[@praveensskillsoft4504]

@@wcandillon thanks for the prompt response. I have gone through and used varying the height of card. Its fine but some glitches as my card is of variable height, anyway to handle that?

[@misterio1980ful]

Hello William. I really enjoy your tutorials you are really good at coding. I got a question do you have the same tutorial in javaScript as you are using typeScript it vary a bit, I tried to create the same animation in javaScript but I struggled a bit.. Thank you again and hope you are having a great day!!!

[@shristysinha3114]

u got a solution, i am stuck in the same.

[@codigosimple1989]

you don't provide starter files to follow through the tutorial so in my case I couldn't follow through, I tried to run your source code but is filled with errors in my text editor and versioning problems

[@Tech4easy2015]

Hey! Noob question. But how would I go about navigating to another screen when clicking a card. My idea is to have different navigation pages for each card

[@Tech4easy2015]

Hey, still looking forward to reply😊

I'm gonna look into it.

[@VinhTruong-fo5bh]

Great!

[@benrobinson6055]

Nice! Would be really interested to hear why reanimated wasn't suitable for this?

[@wcandillon]

On Android, the frame by frame syncing of the scrollview animation value is not precise enough with reanimated. It might be fixed soon in Reanimated

[@thomazcapra5535]

@@wcandillon Is this answer updated?

[@hongngocle6979]

Perfect

[@wcandillon]

glad you liked it :)

[@jbradshaw7]

Nice, but I guess it only works of you have a fixed card height.

why did you use Animated from React instead of reanimated?

[@vasylnahuliak]

02:03 "We had to use the vanilla animated API from react native because here using reanimated that on Android we couldn't get frame by frame full control over the way the element moves"
