Flutter uses git for SDK management. You'd need to review your repository located in $HOME/development/flutter. You can use git command to check your repostory status. For example,
$ git status
To see your local change
$ git branch
To see which branch you are using.
Following steps might help you when you find you've changed something un-committed, but you would like to undo all changed to simply switch to latest version (master).
$ git reset --hard HEAD
To undo all your changes.
$ git checkout master
To switch to master branch
$ git pull
To pull down and sync all commit on server.
