Hi @jukaz, I have issue with enum generation,

type 'EnumElementImpl' is not a subtype of type 'ClassElement' in type cast

code example:

import 'package:hive/hive.dart';

import 'hive_object_types.dart';

part 'project_icon.g.dart';

@HiveType(typeId: HiveObjectTypes.icon)
enum ProjectIcon {
  @HiveField(0)
  heard,

  @HiveField(1)
  mask,
}

thanks
