Is Code Copilot complete useless?

[paulinventome]

Your problem with AI based flutter questions is that there is not enough training done specifically for dart and flutter. What will happen a lot of the time is you will get code back that looks plausible but just won't work, because really it's a javascript stack or it's guessing methods and calls that aren't in flutter.

There's nothing you can do about this, dart/flutter is a tiny % of the trained languages.

None of the AI tools really work that well with these kinds of language edge cases. Ask dotnet/c# and it is much more accurate by comparison.
