Dart:如何实现类似的情况，例如“当hashcode()被覆盖时，==()也应被覆盖"? [英] Dart: How to implement a similar situation like "when hashcode() is overridden, ==() should also be overridden"?

问题描述

当在类中重写hashCode()或==运算符时，飞镖分析器将发出警告，表示另一个方法也应被重写.

When either hashCode() or == operator is overridden in a class, the dart analyzer warns, saying that the other method should also be overridden.

我可以在其他方法上实现类似的情况吗?还是Dart Analyzer提供的特殊功能?

Can I implement a similar case on other methods? Or is this feature a special case provided by Dart Analyzer?

例如，

class A {
  void method1() {}

  void method2() {}
}

class B extends A {
  @override
  void method1() {}
}

在这一点上，我想发出一个警告，指出B类也应该覆盖method2().有可能吗?

At this point I want to produce a warning that class B should also override method2(). Is that possible?

推荐答案

您看到的是一条短绒规则.飞镖分析器实现了许多这样的功能，您可以在此处进行查看，或仅查看该特定规则.
尽管您可以为您的项目自定义静态分析，但据我所知，定制的掉毛规则仍然不可用(至今).

What you are seeing is a linter rule. The dart analyzer implements a bunch of these which you can view here or check out just that specific rule.
While you can customize static analysis for your project, as far as I can tell support for custom linting rules is still not available (yet).
