get method
Returns the specified firewall policy.
Request parameters:
firewallPolicy - Name of the firewall policy to get.
Value must have pattern (firewallPolicies/)?\[0-9\]{0,20}.
$fields - Selector specifying which fields to include in a partial
response.
Completes with a FirewallPolicy.
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<FirewallPolicy> get(
  core.String firewallPolicy, {
  core.String? $fields,
}) async {
  final queryParams_ = <core.String, core.List<core.String>>{
    if ($fields != null) 'fields': [$fields],
  };
  final url_ = 'locations/global/firewallPolicies/' +
      commons.escapeVariable('$firewallPolicy');
  final response_ = await _requester.request(
    url_,
    'GET',
    queryParams: queryParams_,
  );
  return FirewallPolicy.fromJson(
      response_ as core.Map<core.String, core.dynamic>);
