I hade the same problem. I download the flutter SDK. if you don't see the "flutter_windows_v1.12.13+hotfix.9-stable.zip" button then you need to use free VPN extension. After enabling VPN then you might see this "flutter_windows_v1.12.13+hotfix.9-stable.zip" button. download and extract the flutter SDK. setup env variable.

that's how I solved the problem, hope this will work for you.
