AckField class final

Overrides the inferred schema and/or presence for a class-first field.

schema must be a const tear-off of a top-level function returning an Ack schema. The generator validates the declaration and follows its expression. A no-op @AckField() is rejected.

Prefer @Optional() and @Required() for key presence. presence is deprecated and will be removed in 2.0.0.
