I'm making a flutter app with VScode and I have a lot of unused variables declared at the top of the code, but it doesn't show me the underline. Is there a way to setting this?
P.D:The rest of unused code works.
Thank you!
Dart linter and analyzer have no rule for unused global variables, only for local variables. Here is all available rules and diagnostic messages:
https://dart.dev/tools/diagnostic-messages#diagnostics
https://dart-lang.github.io/linter/lints/
So answer is: you can't do that.
There is an open issue on github about opportunity to add custom rules, you can track it - https://github.com/dart-lang/linter/issues/697
