ObjectKey class

A Key backed by the identity of value; equal only when both keys wrap the identical (identical) object.

Use this when value equality is too coarse — two distinct objects that compare equal by == must still be reconciled as separate children (Flutter's classic example: keying list rows by the model object itself so equal-looking entries stay distinct).
