Rikulo security client side login - dart

Question

I've been trying to create a Dart SPA using Rikulo security to log in. I have been unable to do so successfully. I found the following in the docs:
//If you'd like to login in an Ajax request, SOAP or others,
//you can invoke this method directly by providing the username, password
//and, optional, rememberMe:
//prepare username, password, rememberMe from, say, Ajax
security.login(connect, username: username, password: password,
rememberMe: rememberMe, redirect: false);
My question is how do I return a success/fail login value from Rikulo security for use on the client side.
An example would be extremely helpful. Thanks in advance.

I assume you'd like to log in over Ajax (and JSON). Basically, it is no different from handling Ajax -- you can refer to the Handle Post requests section here.
import "dart:convert";
import "package:rikulo_commons/convert.dart";
Future login(HttpConnect connect) {
return readAsJson(connect.request).then((Map<String, String> data) {
return security.login(connect, redirect: false,
username: data["username"],
password: data["password"]);
})
.then((_) {
//login successfully
response
..headers.contentType = contentTypes["json"]
..write(JSON.encode({"result": "success"}));
})
.catchError((ex) {
if (ex is AuthenticationException) {
// login fail
response
..headers.contentType = contentTypes["json"]
..write(JSON.encode({'result': 'fail'}));
} else {
throw new Http404.fromConnect(connect);
}
});
}
