type 'Null' is not a subtype of type 'Object' when serializing Null element in List and Set #190

Currently SerializeObjectFunction does not accept Null as object param, which affects _serializeObject of defaultIterableConverter when any element is null.

Should be able to workaround by changing the signature to 

typedef SerializeObjectFunction = dynamic Function(Object? object, SerializationContext context);

but I am not sure if it has any side-effect.

Delivered, thank you for reporting!
