Why do I get these VS Code errors after running flutter doctor :

Waiting for another flutter command to release the startup lock...

Answer 1

The current release of flutter does not properly detect the VSC extension because of case sensitivity errors. If it shows up in VSCode, it's installed. Ignore Flutter Doctor. :)

Answer 2

There could be several reasons for this, but the most likely cause is that you have VS Code installed but not the Flutter extension.

I get the same:

Run flutter doctor -v for more details as it tells you to in the error message:
