Running flutter doctor spits out error: Standard error: fatal: bad object HEAD

I had installed Flutter and Android Studio from the official websites. I am novice to Git, GitHub, mobile development and android development.

I was trying to run flutter doctor command in the Command Prompt (Windows 10). However, it spits an error in bright red saying:

Failed to find the latest git commit date: VersionCheckError: Command exited with code 128: git -c log.showSignature=false log -n 1 --pretty=format:%ad --date=iso Standard out: Standard error: fatal: bad object HEAD Returning 1970-01-01 05:30:00.000 instead.

Plz help me with this issue. I did face network issues while downloading but I resumed the download in time (in Chrome). I do NOT want to reinstall Flutter all over again because of data issues! Also because setting up this whole thing was really enervating!

You are correct, this is caused by incomplete or corrupted download. You may try the following-

  • initiliase the git repo again by-
git init
  • then fetch the missing files from the remote, by
git fetch
  • If you are facing, some kind of error, like 'your tree is behind HEAD', do-
git pull
  • lastly, check the status by
git status

you should get something like this in output-

On branch stable
Your branch is up to date with 'origin/stable'.

nothing to commit, working tree clean.
