values_declaration_in_enum

A member named 'values' can't be declared in an enum.

The analyzer produces this diagnostic when an enum declaration defines a member named values, whether the member is an enum value, an instance member, or a static member.

Any such member conflicts with the implicit declaration of the static getter named values that returns a list containing all the enum constants.

The following code produces this diagnostic because the enum E defines an instance member named values:

enum E {
  v;
  void values() {}
}

Change the name of the conflicting member:

enum E {
  v;
  void getValues() {}
}
