How do you properly store a genuinely fully custom Dart object, rather than simply a basic primitive type, within Hive using a generated TypeAdapter?

Storing a genuinely fully custom Dart object directly within Hive requires generating a corresponding TypeAdapter, which properly and correctly teaches Hive exactly how to actually serialize that specific particular object down into its own efficient binary storage format and properly deserialize it back again later, and this is typically accomplished by annotating your own custom class with the @HiveType annotation along with individually annotating each specific field you genuinely want persisted with @HiveField, then running the build_runner code generation tool to actually properly generate that specific required adapter code completely automatically for you.

@HiveType(typeId: 0)
class Note extends HiveObject {
  @HiveField(0)
  late String title;

  @HiveField(1)
  late String content;
}
