Issue
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"

Any idea how to solve it?
Solution
Running
pub global activate stagehand
allows it to work again.
