owner property

String? owner
final

owner Indicates the AccountID of the account that owns the corresponding NFToken. If the offer is to buy a token, this field must be present and it must be different than Account (since an offer to buy a token one already holds is meaningless). If the offer is to sell a token, this field must not be present, as the owner is, implicitly, the same as Account (since an offer to sell a token one doesn't already hold is meaningless).

Implementation

/// If the offer is to sell a token, this field must not be
/// present, as the owner is, implicitly, the same as Account
/// (since an offer to sell a token one doesn't already hold
/// is meaningless).
