🔎Provide meaning for your UI.

With the Semantics widget, you can annotate your app UI with meaning. It can provide descriptions, metadata, and more to screen readers and search engines.

SERIOUS BUG of flutter on iOS !
flutter is very popular these days , so i looked for some apps on app store and installed them on my iphone xs 、iphone x and two android phones,then i found a serious bug on ios phones, that is : if you turn the app to background, after a short time, you open this app again and slide on a page of app ( especially a page contains listview ), you will find a serious janky ( skip frame ) happens( maybe not happen every time, but the probability at least 90%), slide over some distance , the janky will disappear.at first, i thought this happens because of a bug of the app , but after i tried many apps , EVERY app has this bug , i came to the conclusion : flutter has a SERIOUS BUG on iOS platform.anyone who has question for my opinion can just try the apps on : https://itsallwidgets.com/because of this bug, i'm confused, i dont know if i shoud continue to use flutter to develop.

First Flutter app on App Store | Feels great
Not sure if this belongs here.Our first fluter app has finally launched on Play store and App store. It has been there for more than a month but now it is much more stable than before.Our first choice of Tech for this app was React Native. We stuck with it for around 3 months with almost no progress. Finally we pushed back and picked Flutter. All the knowledge we gained from RN helped us in Flutter too. I am very proud of the app. It's simplistic, neat and smooth. Not much on features right now but all that will be added soon. Also, it doesn't look like a generic template app which I feel is very important when developing on hybrid frameworks. Each platform has a unique character and keeping that character alive in the app is a great achievement.You can check it out from the link belowhttps://weddingz.page.link/reddit​Feel free to ask any questions.
