rest - Dart RPC and object hierarchies -

this basic question rest apis. started reading docs , don't see how implement api object/model has sub-objects. instead there description of objects primitives (int, string, etc).

is there example object hierarchy? or maybe server model uses ids in class definitions refer sub-objects, how google's ndb it?

from docs:

currently supported types public fields int, double, bool, string, datetime, list, map, , message class.

this means can create structure need, requirement objects in must constructed of in particular way.

an example:

class person {   string name;   int age }  class address {   string city;   string street; }  class school {   list<person> staff;   person headmaster;   list<person> students;   address address; } 

one limitation did not cannot use inheritance in these classes, again whole point of rpc package create api can consumed client, not dart code.
