Dart-Code: "Failed to initialize Flutter: Process exited with code 1" after upgrade to Flutter 1.22

Steps to Reproduce

Upgrade to Flutter 1.22 on Stable channel
Flutter doctor
Open any project in VS Code (1.49.2)
Error: “Failed to initialize Flutter: Process exited with code 1.”

Restarting, flutter clean, uninstall re-install Flutter Extension, all have no effect. Thanks very much for all the hard work!

@tony123S it looks like the engine.version file in your SDK contains Git conflict markers (this could happen if something tried to merge two Git branches together - though I’m not sure how that would occur).

The easiest way to fix this would be to re-extract the SDK if you got it from a zip. Running git reset --hard 2.0.1 from the terminal inside your Flutter SDK folder would probably also work (note: this will discard any local modifications in your Flutter SDK, though unless you’re contributing to the Flutter SDK I would not expect you to have any).

Using git clean and git pull related commands didn’t work, but deleting the flutter folder and downloading a fresh copy of Flutter to install solved the problem. Thanks so much Dan!

At a later time I’ll try to get the git version of flutter working.
