Flutter authentication error although I am passing the required arguments to the endpoint-CodePudding

I am trying to sign up a user by posting to the endpoint with the required data, it works perfectly but the API returns an error message of fullName is required. As you can see clearly, I am passing the name to the fullName in the call.

Future<Map<String, dynamic>> signup({
    required String name,
    required String email,
    required String password,
  }) async {
    try {
      Response response = await dio.post(Api.SIGN_UP, data: {
        'fullName': name,
        'email': email,
        'password': password,
      });

      final responseData = response.data;
      print(responseData.toString());
      return responseData;
    } on DioError catch (err) {
      print(err.error);
      throw CustomException(err.message);
    } catch (error) {
      throw CustomException('An error occured. Please try again later');
    }
  }

Below is the endpoint I want to make the call to:

class Api {
  // DIO OPTIONS
  static var options = BaseOptions(
    baseUrl: 'http://localhost:3000/api/',
    connectTimeout: 5000,
    receiveTimeout: 3000,
  );
  static const SIGN_UP = 'onboarding/signup';
}

I tried in using postman to do it and it works correctly and signs up the user. I don't know where the error is coming from, whether the Dio or the backend.

CodePudding user response：

add this to headers

"Accept": "application/json",

CodePudding user response：

Add response type, and content type to your deo option

static var options = BaseOptions(
    baseUrl: 'http://localhost:3000/api/',
    connectTimeout: 5000,
    receiveTimeout: 3000,
    responseType: ResponseType.plain,
    contentType: Headers.jsonContentType,
  );
