Stagehand doesn't support Dart 2.3.1 error

原文 2019-09-05 12:34:07 6 1 flutter/ dart/ flutter-web/ stagehand

I got a "Dart upgrade" in VS Code (win10) right after when I try to create a new flutter web project I got

Unable to execute Stagehand. Stagehand exited with code 65. stagehand 3.3.2 doesn't support Dart 2.3.1.

given that I didn't have this problem before, I'm assuming that it's caused by the update.

I run "flutter upgrade" and this is my flutter doctor

and this is my "flutter --version"

Flutter 1.7.8+hotfix.4 • channel stable • https://github.com/flutter/flutter.git Framework • revision 20e59316b8 (7 weeks ago) • 2019-07-18 20:04:33 -0700 Engine • revision fee001c93f Tools • Dart 2.4.0

Any idea how to solve it?
