avoid_renaming_method_parameters

The parameter name '{0}' doesn't match the name '{1}' in the overridden method.

The analyzer produces this diagnostic when a method that overrides a method from a superclass changes the names of the parameters.

The following code produces this diagnostic because the parameter of the method m in B is named b, which is different from the name of the overridden method's parameter in A:

class A {
  void m(int a) {}
}

class B extends A {
  @override
  void m(int b) {}
}

Rename one of the parameters so that they are the same:

class A {
  void m(int a) {}
}

class B extends A {
  @override
  void m(int a) {}
}
