Implementation

static Future<Status> resetPassword(
  String emailOrUserID, {
  final UriProductHelper uriHelper = uriHelperFoodProd,
  final OpenFoodFactsLanguage? language,
  final OpenFoodFactsCountry? country,
}) async {
  Uri passwordResetUri = uriHelper.getUri(
    path: '/cgi/reset_password.pl',
    addUserAgentParameters: false,
  );

  if (language != null || country != null) {
    passwordResetUri = UriHelper.replaceSubdomain(
      passwordResetUri,
      language: language,
      country: country,
    );
  }

    'type': 'send_email',
    '.submit': 'Submit',

    return Status(
      status: Status.serverErrorStatus,
      error: Status.serverErrorInEnglish,
    );
  }

  // Basically, if we see explicit errors or an html form, it's not good.
  const List<String> errors = <String>[
