private static final String DEFAULT_NULLABLE
NULLABLE_OPTIONback to summary
pack-priv static final String NULLABLE_OPTION

If set to a non-empty string, defines which @Nullable type annotation should be used by default. If set to an empty string, does not insert @Nullable unless it is referenced in the @AutoValue methods. If unset, defaults to DEFAULT_NULLABLE.
