[Flutter] When accessing the ID variable in isar database it returns the same variable in all...

I have a model called TransactionModel:

class TransactionModel {
final Id keyID = Isar.autoIncrement;
final DateTime dateTransaction;
final String concept;
final double amountDouble;
}


When I use:

print(data.keyID.toString());

-9223372036854775808
