listDocuments method

Future<ListDocumentsResponse> listDocuments(String parent, String collectionId, { List<String>? mask_fieldPaths, String? orderBy, int? pageSize, String? pageToken, String? readTime, bool? showMissing, String? transaction, String? $fields, })

Lists documents.

Request parameters:

parent - Required. The parent resource name. In the format: projects/{project_id}/databases/{database_id}/documents or projects/{project_id}/databases/{database_id}/documents/{document_path}. For example: projects/my-project/databases/my-database/documents or projects/my-project/databases/my-database/documents/chatrooms/my-chatroom Value must have pattern ^projects/\[^/\]+/databases/\[^/\]+/documents$.

collectionId - Required. The collection ID, relative to parent, to list. For example: chatrooms or messages.

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

orderBy - The order to sort results by. For example: priority desc, name.

pageSize - The maximum number of documents to return.

pageToken - The next_page_token value returned from a previous List request, if any.

readTime - Reads documents as they were at the given time. This may not be older than 270 seconds.

showMissing - If the list should show missing documents. A missing document is a document that does not exist but has sub-documents. These documents will be returned with a key but will not have fields, Document.create_time, or Document.update_time set. Requests with show_missing may not specify where or order_by.

transaction - Reads documents in a transaction.

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

Completes with a ListDocumentsResponse.

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.
