var_with_no_type_annotation lint fires when using a var modifier with no type annotation in a formal parameter list. This is a preparatory lint that helps us migrate to Dart 3.13. All violations from this lint will become compile-time errors in Dart 3.13 when the primary constructors feature ships.

Fixes: dart-lang/sdk#62590

Related to breaking changes: There should be nothing that breaks from adding this lint. Function types with var are already a compile-time error and any customers overriding a method with a var parameter won't break their code.

// Framework code
class C {
  void m(int x) { ... } // Removed var here.
}

// ...

// User code
class B implements C {
  void m(var int x) { ... } // Will still work.
}

This change should be test exempt.

Pre-launch Checklist

If you need help, consider asking for advice on the #hackers-new channel on Discord.

If this change needs to override an active code freeze, provide a comment explaining why. The code freeze workflow can be overridden by code reviewers. See pinned issues for any active code freezes with guidance.

Note: The Flutter team is currently trialing the use of Gemini Code Assist for GitHub. Comments from the gemini-code-assist bot should not be taken as authoritative feedback from the Flutter team. If you find its comments useful you can update your code accordingly, but if you are unsure or disagree with the feedback, please feel free to wait for a Flutter team member's review for guidance on which automated comments should be addressed.
