Recently I had installed flutter plugin in android studio. And when I went for new project, it asked me flutter sdk. I chosen "Install SDK". And it was freezes at ""Unzipping Dart SDK". I kept as it is for more than 3hrs, but was there is no any response.
Please can any one help me to continue....

Copied from original issue: flutter/flutter#15485

same problem. Seems many people met this, it's not a new one. I met this when run "flutter dector" in cmd, it just hung at Unzipping Dart SDK... forever.
I work on Windows

@pq, can you look at what this step is doing that it might fail at? Is this after we've cloned? Is this message coming from flutter_tools?

@hanzhida, re:

Do you have references to other issues? I'm wondering if they might have some additional details, like if we're hitting issues with a virus checker.

flutter/flutter#11698
Seems some people also met this. It's better if it shows more detailed information.

@devoncarew: 👍 Looking now.

@hanzhida : thanks for the report and the extra context!

I'm also facing the same issue and nothing is happening.

Followed the instructions by c-born in flutter/flutter#11698, , I solved this problem. Great!!

I installed the latest 7Zip and added its directory (C:\Program Files\7-Zip) to my PATH
I also installed the latest PowerShell from https://www.microsoft.com/en-us/download/details.aspx?id=54616

Thanks for all the follow-ups. While the issue is coming up out of flutter_tools (and should be fixed there), I'm looking at our installation logic to see how we can harden it a little.
