patch method

Future<Document> patch(Document request, String name, { bool? currentDocument_exists, String? currentDocument_updateTime, List<String>? mask_fieldPaths, List<String>? updateMask_fieldPaths, String? $fields, })

Updates or inserts a document.

request - The metadata request object.

Request parameters:

name - The resource name of the document, for example projects/{project_id}/databases/{database_id}/documents/{document_path}. Value must have pattern ^projects/\[^/\]+/databases/\[^/\]+/documents/\[^/\]+/.*$.

currentDocument_exists - When set to true, the target document must exist. When set to false, the target document must not exist.

currentDocument_updateTime - When set, the target document must exist and have been last updated at that time. Timestamp must be microsecond aligned.

mask_fieldPaths - The list of field paths in the mask. See Document.fields for a field path syntax reference.

updateMask_fieldPaths - The list of field paths in the mask. See Document.fields for a field path syntax reference.

$fields - Selector specifying which fields to include in a partial response.

Completes with a Document.

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.
