After do above task now try to upgrade again Flutter but got again error mentioned below

My-Mac:flutter admin$ flutter upgrade
    Building flutter tool...
    Because flutter_tools depends on sockjs_client 0.3.5 which doesn't match any versions, version solving failed.
    Error: Unable to 'pub upgrade' flutter tool. Retrying in five seconds... (9 tries left)
    .
    .
    Error: Unable to 'pub upgrade' flutter tool. Retrying in five seconds... (1 tries left)
    Command 'pub upgrade' still failed after 10 tries, giving up.

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.
