Future<Operation> 
create(
    
- LogicalView request,
- String parent, {
- String? logicalViewId,
- String? $fields,
Creates a logical view within an instance.
request - The metadata request object.
Request parameters:
parent - Required. The parent instance where this logical view will be
created. Format: projects/{project}/instances/{instance}.
Value must have pattern ^projects/\[^/\]+/instances/\[^/\]+$.
logicalViewId - Required. The ID to use for the logical view, which will
become the final component of the logical view's resource name.
$fields - Selector specifying which fields to include in a partial
response.
Completes with a Operation.
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.
