Missing error "Flutter requires PowerShell 5.0 or newer." in IDE #1892
Description
The error below is printed in the flutter console (flutter\flutter_console.bat) but VS code and Android studio console (flutter\bin\flutter.bat) do nothing (just waiting for resources), so users who have Powershell below 5.0 don't know that they need to upgrade. This is likely to affect those on Windows 7
It happens after running one of the following commands:
flutter upgrade
flutter update
flutter doctor
Environment variables are set up as follows:
C:\Windows\System32;
E:\flutter\flutter\bin;
E:\git\Git\bin;

Thanks! This is because we don't route all of the output to the console during the setup (because we replace it with a progress indicator). I've changed to now show an error message when this occurs.

Thanks Danny,
"...PowerShell 8.0..." - typo? Just to confirm, I've updated PS to 5.1 and all is working fine now.

Heh, the real message from Flutter will be passed through to the UI. I just changed Flutter to temporarily need "PowerShell 8" so that I could test it (since I already had >= 5) 😄

@Emred360 there's a link in the comment above - it's part of the Windows Management Framework.

@DanTup Thanks for your reply. I have updated my PowerShell.
But I have a new issue which I've been battling with for a long time now.
DanTup commentedon Oct 13, 2020
@Emred360 that seems like a Gradle issue rather than the VS Code plugin so it's not something I'm familiar with. However if the error is to believed, it seems like it's trying to allocate 1.5GB for the heap (possible because Java was launched with
Xxm1536?) but is unable to (this may be because you don't have enough RAM).You may wish to try some of the suggestions on StackOverflow:
