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 - Optional. The collection ID, relative to parent, to list. For example: chatrooms or messages. This is optional, and when not provided, Firestore will list documents from all collections under the provided parent.

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

orderBy - Optional. The optional ordering of the documents to return. For example: priority desc, __name__ desc. This mirrors the ORDER BY used in Firestore queries but in a string representation. When absent, documents are ordered based on __name__ ASC.

pageSize - Optional. The maximum number of documents to return in a single response. Firestore may return fewer than this value.

pageToken - Optional. A page token, received from a previous ListDocuments response. Provide this to retrieve the subsequent page. When paginating, all other parameters (with the exception of page_size) must match the values set in the request that generated the page token.

readTime - Perform the read at the provided time. This must be a microsecond precision timestamp within the past one hour, or if Point-in-Time Recovery is enabled, can additionally be a whole minute timestamp within the past 7 days.

showMissing - If the list should show missing documents. A document is missing if it does not exist, but there are sub-documents nested underneath it. When true, such missing documents will be returned with a key but will not have fields, create_time, or update_time set. Requests with show_missing may not specify where or order_by.

transaction - Perform the read as part of an already active 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.
