FutureBuilder does not get into builder?

I want to get two parameters from createUser response. I have a raisedbutton and i want to use FutureBuilder when onPressed.
future property works well, but i can not get in builder property. I tried everything but i could not find solution. 

...
RaisedButton(
        elevation: 5.0,
        onPressed: (){
          FutureBuilder(
              future: createUser(usernameController.text, emailController.text, passwordController.text, '1', 1),
              builder: (context, snapshot) {
                if (snapshot.hasData) {
                  saveLogin(snapshot.data.userUnique);
                  nextScreen(
                      context,
                      UserDetail(
                        userUnique: snapshot.data.userUnique,
                      ));
                } else {
                  return MyHomePage();
                }
                return MyHomePage();
              });
        },
...


Future createUser(String username, String password, String email,
    String logintype, int userUnique) async {
  String url =
      "http://api.xx.com/api/register?username=$username&password=$password&email=$email&logintype=$logintype&userUnique=$userUnique";

  final response =
      await http.get(url, headers: {'Content-Type': 'application/json'});
  return registerFromJson(utf8.decode(response.bodyBytes));

I changed FutureBuilder to async / await method

thanks for your help @pskink

onPressed: () async {
                            var xx = await createUser( usernameController.text, emailController.text, passwordController.text, '1',userUnique());
                            print(xx.responseCode.toString());
                            print(xx.userUnique.toString());
                            saveLogin(userUnique());

                          },
