It's actually cool that they brought out the actual engineers responsible for maintaining the respective components to discuss these topics

[@zeebradoom4774]

literally what I've been looking for!

[@user-fi2wt8du1m]

Just yesterday, while developing an app with multiple listviews, I gave up while debugging whether the iOS tab bar touch function was not working. Magically, this video has been chosen by the algorithm, and I'm going to deal with the issue.

[@Valeriaduranruiz]

Kate you are excellent! And your voice is like butter 🧈 (that’s a good thing , just in case you don’t love butter)

🤩 I will scroll up and down until I will find you... Nice voice, professional explained

[@wgolyoko]

Weirdly, this just unlocked comprehension of primaryFocus. Thanks !

[@laybunzz]

That's awesome to hear! Feel free to share what finally clicked or what you were missing - that might help us communicate about focus in the future :)

[@abdelrahmananwar885]

Thanks for sharing this great content

[@nipunshah1373]

1 question : Do intents for scroll up and scroll down on page up/down will be automatically handled by flutter for Focus systems ??

[@kurokitty1]

This was awesome, thanks!

[@karo7752]

An alternative option is ignore the error on web which Ive shamefully done for the past year. Maybe Ive contributed to the decision of making this video by the sheer number of errors coming into the flutter dev team analytics

[@laybunzz]

lolol

[@michaelmboya5085]

Awesome content. The Flutter team are just 🔥🔥🔥

[@flutterdev]

Thanks so much for your kind words. Have you checked out the documentation that goes along with the video? You can view it here: goo.gle/3poOjF5 😁

[@ayo-vz7jc]

Any way to get the iOS tab bar click event with my own scrollController? so that I can move my listview to the top. :)

[@maheshjamdade1]

Thank you so much for explaining it in simple words 🙏

[@bizeedolimited31]

Best ever ❤️

[@hitheshchowdary4366]

Awesome, thank you 😀👍

[@haidernaqvi87]

I have a chat app and want to scroll the SingleChildScrollView to a specific message like Whatsapp does when you reply to a message

[@jeison_sanches]

I learned this the hard way a few weeks ago while trying to implement some rather unusual behavior for a multi scroll screen. Really helpful video!

[@flutterdev]

We're delighted to hear that the tutorial was helpful for you! Be sure to check out the documentation for PrimaryScrollController here: goo.gle/3poOjF5 👍

[@magacaygamaxamuud7253]

thanks ++

[@tonyraulblancofernandez9632]

I 💙 kate voice!!!

[@Pesthuf]

I wish the web had this. There are many scenarios where your main scrollable isn't the document itself, but doing that causes various issues on mobile browsers...

[@andersmorille7653]

She said that this was the same default for web and desktop, so it should work as intended; or are you having problems? I'm working on web so it would be useful to know!

[@mushaheeed]

Where's the google io link?

[@walidloubar114]

kate the best

[@MohammadMalan]

The more you know

[@sarahfortunes6361]

:)

[@user-ev4nt1qd1c]

so ASMRxDeveloping is a thing now, and it's my new fetish I guess

[@whoeverofhowevermany]

I think you should apologize to all the people born on a holiday

[@prasantkumar7693]

Awesome content

[@flutterdev]

We're glad you're enjoying the content! We work hard to create great videos for you all, and it means a lot to us when you let us know what we're doing is awesome 😀

[@hawarhekmat1174]

Don't know it's me or something else, but when i attach a controller to a listview it won't activate untill user scrolls which is not good, when i want to execute some code via initState to check if user is a very bottom of screen for example set unseen chat to seen, but that won't work unless user scrolls then that code executes, 🥹

[@laybunzz]

Can you share a DartPad link that reproduces this?

[@flutterdev]

Hello Hawar! Please file a report on github so that we can investigate further. goo.gle/3DrQDUl
