Flutter is somehow v0.0.0, making it entirely unusable

I did a fresh install a few minutes ago, and flutter doctor -v gave me this:

root@localhost:~/notes-app# flutter doctor -v
   Woah! You appear to be trying to run flutter as root.
   We strongly recommend running the flutter tool without superuser privileges.

Any flutter app which depends on some specific version of flutter will error and refuse to build because flutter version is 0.0.0 and none app would want to target 0.0.0 flutter version.

Also, can flutter version be updated? Doctor said they downloaded version was released 9 months ago :(
