defaultProperties property Null safety

List<String>? defaultProperties

The list of default property names of this object.

By default, a Query will fetch the properties in this list. You may specify a different set of properties by setting the Query.returningProperties value. The default set of properties is a list of all attributes that do not have the Column.shouldOmitByDefault flag set in their Column and all ManagedRelationshipType.belongsTo relationships.

This list cannot be modified.

        .where((prop) => !prop!.isTransient)
        .map((prop) => prop!.name));

        .where((prop) =>
            prop!.isIncludedInDefaultResultSet &&
            prop.relationshipType == ManagedRelationshipType.belongsTo)
        .map((prop) => prop!.name));
