listAll method
List all items (files) and prefixes (folders) under this storage reference. List API is only available for Firebase Rules Version 2.
This is a helper method for calling list() repeatedly until there are no more results. The default pagination size is 1000.
Note: The results may not be consistent if objects are changed while this operation is running.
Warning: listAll may potentially consume too many resources if there are too many results.
Implementation
Future<ListResult> listAll() =>
handleThenable(jsObject.listAll()).then(ListResult.getInstance);
