Servicestack Service implementation to reproduce issue with dart-ref.
generated service reference: foos.dtos.dart
Using JsonServiceClient to get data from backend:
var client = new JsonServiceClient("http://localhost:5000");
var response = await client.get(new GetFoos());Results in this exception (screenshot taken from flutter app on ios simulator):
The call to createInstance() is in json_converters.dart where typeInfo is null.
We wrap retrieving lists in a PagedResult which leads to this problem. Using ts-ref/typescripts JsonServiceClient works perfectly fine in our other aurelia SPAs with these dtos and the same backend.
Backend:
public class FooService : Service
{
public PagedResult<FooListDto> Get(GetFoos request)
{
var list = new List<FooListDto>
{
new FooListDto {Id = "claims/1-A"},
};
return new PagedResult<FooListDto>(list, 1, 1, 1);
}
}

{
}
