Describe the bug

updateRegistrationFlowBody requires

• flow - Flow ID as string
• updateRegistrationFlowBody - builder function to create flow body

Unfortunately creating UpdateRegistrationFlowBody provides only oneOf, whereas auto-generated docs describe the required for me arguments like method, traits and so on.

I have tried creating flow body with following snippets with no success:

1

  final body = UpdateRegistrationFlowBody((b) => b
    ..oneOf = UpdateRegistrationFlowWithPasswordMethod((p) => p
      ..password = password
      ..traits = Traits((t) => t..email = email)));

  kratosClient
      .updateRegistrationFlow(
        flow: registrationFlow.id,
        updateRegistrationFlowBody: body,
      )

2

final body = UpdateRegistrationFlowBody((b) => b
  ..oneOf = OneOf<UpdateRegistrationFlowWithPasswordMethod>.of(
    UpdateRegistrationFlowWithPasswordMethod(
      (b) => b..password = password
    )
  )
);

This package however provides needed function to create flow body - SubmitSelfServiceRegistrationFlowBody

Reproducing the bug

1. Create RegistrationFlow
2. Try to update its body

@Nelfimov Hi, I finally found a solution after really a long time of digging. I had the same problem as you.
So, first of all, we missing a lot of documentation on the dart client. You will need two package in order to have it working: OneOf and built_value.

Then I had it working doing so (this is maybe not the best way of doing it but since it was a error and try attempt, I didn't wanted to loose more time having it working):

final Response<SuccessfulNativeRegistration> response;
final JsonObject jsonObject = JsonObject(registrationModel.toJson());

    final UpdateRegistrationFlowBody registrationFlowBody =
        UpdateRegistrationFlowBody(
      (UpdateRegistrationFlowBodyBuilder flow) => flow
        ..oneOf = OneOf.fromValue1(
          value: UpdateRegistrationFlowWithPasswordMethod(
            (UpdateRegistrationFlowWithPasswordMethodBuilder builder) => builder
              ..csrfToken = ''
              ..traits = jsonObject
              ..method = 'password'
              ..password = registrationModel.password,
          ),
        ),
    );

      response = await _oryFrontEnd.updateRegistrationFlow(
        flow: url,
        updateRegistrationFlowBody: registrationFlowBody,
      );

Hope it will help you in future development !
