Lint for unused widgets and widget parameters

[rasitayaz]

It would be great to be able to see if a widget/widget property is unnecessary and not used.

Examples
Let's say I've created a widget and decided not to use it at some point in the app's development, but forgot to delete it from the project. So it will stay there forever unless I come across by chance. Same thing with the widget properties.

@rasitayaz hi, if you're interested in checking for unused code (like unused declared widgets), you can try https://dartcodemetrics.dev/docs/cli/check-unused-code (we also provide other commands for code refactoring)

thank you, couldn't find this as a rule on https://dart-lang.github.io/linter/lints/index.html. can i enable this as a linter rule in my analysis_options.yaml to display warnings if there is any unused code?

[incendial]

Nope, it's a separate package and this is a cli command. Running such check as linter rule will be quite memory expensive and might make the overall dev experience worse.

ok, thanks a lot, closing the issue 👍
