Hi, has anyone tried to automate generating DiffUtil.Callback methods? Mostly `areContentsTheSame`and `getChangePayload`)

Say I have a model, the usual case fo areItemsEqual is to use equals(), but what if I dont want to compare all the fields?

So, I could write a reflection util / codegen for this, but it requires to have some sort of a @Exclude annotation on a given field

*which in turn means that our data/domain layer Foo model knows about diff util stuff
so not sure if this is the way to go*

should it maybe be manual code and keep reflection (traversing all the fields) unit test to check if new fields are added) (edited)

-- or, create a UI layer level model from it, and use just the plain equals from it (or not, doesnt matter, since now diffutil annotations make sense)

Umm you can you use a annotation processor. and add annotations for the comparable fields
