Future<BuildTrigger> 
create(
    
- BuildTrigger request,
- String parent, {
- String? projectId,
- String? $fields,
Creates a new BuildTrigger.
request - The metadata request object.
Request parameters:
parent - The parent resource where this trigger will be created. Format:
projects/{project}/locations/{location}
Value must have pattern ^projects/\[^/\]+/locations/\[^/\]+$.
projectId - Required. ID of the project for which to configure automatic
builds.
$fields - Selector specifying which fields to include in a partial
response.

Completes with a commons.ApiRequestError if the API endpoint returned an error.
If the used http_1.Client completes with an error when making a REST
call, this method will complete with the same error.
