delete method
Deletes a conversation.
Request parameters:
name - Required. The name of the conversation to delete.
Value must have pattern
^projects/\[^/\]+/locations/\[^/\]+/conversations/\[^/\]+$.
force - If set to true, all of this conversation's analyses will also be
deleted. Otherwise, the request will only succeed if the conversation has
no analyses.
$fields - Selector specifying which fields to include in a partial
response.
Completes with a GoogleProtobufEmpty.
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<GoogleProtobufEmpty> delete(
  core.String name, {
  core.bool? force,
  core.String? $fields,
}) async {
  final queryParams_ = <core.String, core.List<core.String>>{
    if (force != null) 'force': ['${force}'],
    if ($fields != null) 'fields': [$fields],
  };
  final url_ = 'v1/' + core.Uri.encodeFull('$name');
  final response_ = await _requester.request(
    url_,
    'DELETE',
    queryParams: queryParams_,
  );
  return GoogleProtobufEmpty.fromJson(
      response_ as core.Map<core.String, core.dynamic>);
