Issue with EnumDeclarationsMacro

[BirjuVachhani]

I was playing with macros on enums with following macro:

macro class EnumTest implements EnumDeclarationsMacro {
  const EnumTest();

  @override
  FutureOr<void> buildDeclarationsForEnum(EnumDeclaration enuum, EnumDeclarationBuilder builder) {
    builder.declareInType(DeclarationCode.fromParts([
      'void test() {',
      'print("Hello World");',
      '}',
    ]));
  }
}

Usage:

void main() {
  UserPlan userPlan = UserPlan.free;
  userPlan.test(); // Error test method is not found.
}

@EnumTest()
enum UserPlan { free, premium, team, business }

This results into an error where the test method is not found/generated. The same operation on a class with ClassDeclarationsMacro works just fine. It adds a method called test in the class declarations. I was expecting the same with enums. Is this a bug or am I missing something here?
