Visual Studio Code Flutter Cannot Update Dart SDK

Question

Because depends on cupertino_icons >=1.0.1 which requires SDK version >=2.12.0-0 <3.0.0, version solving failed.

whenever I tried to flutter run, flutter pub get, flutter pub upgrade, I got this return in console.. I also have tried flutter update-packages it returns

Flutter is already up to date on channel stable Flutter 1.22.5 • channel stable • https://github.com/flutter/flutter.git Framework • revision 7891006299 (3 weeks ago) • 2020-12-10 11:54:40 -0800 Engine • revision ae90085a84 Tools • Dart 2.10.4

How can I update Dart SDK?

First, you already have the latest versions for Flutter and Dart. Second, this is not a problem of Dart version, read this page. — Ουιλιαμ Αρκευα

you should use 1.0.0 version of cupertino in your pubspec.yaml. I think there is a problem with new version of cupertino

 cupertino_icons: ^1.0.0

Thank you, downgrade the package.. Its one of a good idea, but how can't I update the Dart SDK into the newest version?I just don't understand, eventho I did "Flutter Upgrade"... the dart sdk version still not the newest

do what I said and run flutter upgrade if you face with that 'Flutter is already up to date on channel stable' there is no problem no need to upgrade yet if I helped you a little bit can you like my post –

As of 2021-03-10 or earlier, it is no longer necessary to use cupertino_icons 1.0.0 or switch to the beta update channel (flutter channel beta). Just upgrade (flutter upgrade) and re-run flutter pub get. For details, see issue 72231.

False. It is needed to change to dev branch: github.com/flutter/flutter/issues/72231#issuecomment-774627170
