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!

@pskink where is that file? – Gal Nezah Jan 21 '21 at 07:46

@pskink it seems I don't have it... – Gal Nezah Jan 21 '21 at 07:48

@SamChan doesn't work. I think this is for the imported packages, not declared variables. – Gal Nezah Jan 21 '21 at 07:50

1so check [The analysis options file](https://dart.dev/guides/language/analysis-options#the-analysis-options-file) – pskink Jan 21 '21 at 07:54

@pskink wow! we are on the right way... I see that is there a lot of config options there! Do you know what is the one that helps me? – Gal Nezah Jan 21 '21 at 07:59

`unused_local_variable: warning` – pskink Jan 21 '21 at 08:10

but apparently it is not working for global variable which is your case? ("*and I have a lot of unused variables declared at the top of the code*") – pskink Jan 21 '21 at 08:18

@pskink Yes, it doesn't work for globals. – Gal Nezah Jan 21 '21 at 08:19

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
