Missing Signup options cause NoSuchMethodError about amplify-flutter HOT 5 CLOSED

@JamesMcIntosh We can't make the options field required at this time, but we ARE implementing a fix to serializeAsMap call as you suggested. The result will be a response from the platform code indicating that this request is malformed, which should hopefull be more helpful.

Thanks for posting this issue.

@haverchuck Sounds good as long as the platform code error explains that it's the option field missing

@JamesMcIntosh A fix for this bug was released today in version 0.0.1-dev.3, so will go ahead and close it out. Please give it a try and let us know if you are still facing issues, and we can look into it.

@JamesMcIntosh I don't think we are currently surfacing the specific fields that are missing, but we are looking at large, general improvement to our error handling, so please be patient. We are aware that this (and other) error visibility issues exist.

Hi, I update amplify_auth_cognito to ^ 0.2.1, then I made this solution

class QCSignUpOptions extends SignUpOptions {
  final Map<String, String> options;
  const MySignUpOptions({required this.options}) : super(userAttributes: options);
  @override
  Map<String, dynamic> serializeAsMap() {
    return options;
  }
}

And finally

 var options = Map<String, String>();
      options["foo"] = "foo";
      options["bar"] = "bar";

var signUpOptions = QCSignUpOptions(options: options);

      await Amplify.Auth.signUp(
          username: emailController.text,
          password: passwordController.text,
          options: signUpOptions);
