list method
Retrieves a list of billing rates.
This method supports paging.
Request parameters:
profileId - User profile ID associated with this request.
Value must have pattern ^\[^/\]+$.
billingProfileId - Billing profile ID of this billing rate.
Value must have pattern ^\[^/\]+$.
$fields - Selector specifying which fields to include in a partial
response.
Completes with a BillingRatesListResponse.
Completes with a commons.ApiRequestError if the API endpoint returned an error.
If the used http.Client completes with an error when making a REST call,
this method will complete with the same error.
Implementation
async.Future<BillingRatesListResponse> list(
  core.String profileId,
  core.String billingProfileId, {
  core.String? $fields,
}) async {
  final queryParams_ = <core.String, core.List<core.String>>{
    if ($fields != null) 'fields': [$fields],
  };
  final url_ =
      'userprofiles/' +
      core.Uri.encodeFull('$profileId') +
      '/billingProfiles/' +
      core.Uri.encodeFull('$billingProfileId') +
      '/billingRates';
  final response_ = await _requester.request(
    url_,
    'GET',
    queryParams: queryParams_,
  );
  return BillingRatesListResponse.fromJson(
    response_ as core.Map<core.String, core.dynamic>,
  );
