I would like to write a new custom linter rule.

Especially, I want to write a rule that forbids the use of the setState function in flutter.

Is there any solution to customize your linter rules out there?

  • I have no experience with it, but there is a [custom_lint](https://pub.dev/packages/custom_lint) package that allows creating custom rules. However, using it requires running a separate command and not the usual `dart analyze`/`flutter analyze` commands. – jamesdlin Jul 14 '22 at 07:28

Yes, you can certainly do that. But why would you want to ban setState?

  • I agree, why would you do that? However, you can't customize the analyzer to do what the question asked via analysis_options.yaml. It would require custom hooks into the analysis server which is much more involved. But again... why would you ban `setState`? – Nico Spencer Jul 14 '22 at 03:52

Doing this kind of analysis would require an analysis server plugin. There's is an API and a Analyzer Plugin Package to do this as well as a view examples of projects using it.
