Hi I've checkout your Project and tried to build it.

But after the command "flutter pub run build_runner build" the Adapter class was missing.

`
import 'package:freezed_annotation/freezed_annotation.dart';
import 'package:hive/hive.dart';

part 'demo.freezed.dart';
part 'demo.g.dart';

@freezed
class Demo with _$Demo {
@HiveType(typeId: 0, adapterName: 'DemoAdapter')
factory Demo({
@HiveField(0) required int val,
}) = _Demo;

factory Demo.fromJson(Map<String, dynamic> json) => _$DemoFromJson(json);

}

`

As shown above I have added the new line.

I was able to generate the Adapter class by moving the HiveType above the class.

`@freezed
@HiveType(typeId: 0, adapterName: 'DemoAdapter')
class Demo with _$Demo {
factory Demo({
@HiveField(0) required int val,
}) = _Demo;

factory Demo.fromJson(Map<String, dynamic> json) => _$DemoFromJson(json);
}

But this runs into the Problem that the required field is not set inside the read function.
Demo read(BinaryReader reader) {
final numOfFields = reader.readByte();
final fields = <int, dynamic>{
for (int i = 0; i < numOfFields; i++) reader.readByte(): reader.read(),
};
return Demo();
}`

Did this workaround still work?

Sincerely,
Zaim
