Dart Restful Server doesnt show response data - dart

Question

I was not 100% sure on how to create a Restful Dart API I can make calls to, but i wanted to try. I wrote the following code:
import "package:rpc/rpc.dart";
import "dart:io";
final ApiServer _apiServer = new ApiServer(prettyPrint:true);
main() async{
_apiServer.addApi(new TestServer());
HttpServer server = await HttpServer.bind(InternetAddress.ANY_IP_V4, 8088);
server.listen(_apiServer.httpRequestHandler);
print('Server listening on http://${server.address.host}:'
'${server.port}');
}
#ApiClass(name:'test_server', version: 'v1', description: 'This is a test server api to ping for some quick sample data.')
class TestServer {
#ApiMethod(method:'GET', path: 'users')
List<User> getUsers(){
List<User> users = new List<User>();
return users;
}
#ApiMethod(method: 'GET', path: 'users/{id}')
User getUser(int id){
User u;
///TODO: Guts of User.
u = new User(id, "f_test_$id", "f_test_$id");
return u;
}
#ApiMethod(method:'POST', path: 'users/user/{id}/add')
User postUser(int id, UserData usr){
User u;
///TODO: Post the user.
u = User.fromUsrData(usr);
return u;
}
}
It is a pretty simple, small one which isnt actually doing anything.
When I run the dart file it will say something like:
Observatory listening on http://127.0.0.1:64969
Server listening on http://0.0.0.0:8088
So it makes me believe that i should be able to ping the server in localhost. I make a call in my browser to http://localhost:8088/test_server/v1/users
and it says: {"error":{"code":400,"message":"Invalid request, missing API name and/or version: http://localhost:8088/."}} which confuses me.
Did i do something wrong somewhere in my definition or how to access the localhost API?
EDIT It seems that when I go to that URL, it sits in a perpetual state of pending. It doesnt do do anything other than that.

Answer 1

After a deeper understanding of the issue, changing the name around etc, It seems that my server was having some issues so i needed to end the Dart execution, and restart the server.
When trying to go to the link again: http://localhost:8088/test/v1/users
it worked exactly as it should.
