getDirectoryMetadata method
Retrieves a directory's contents' metadata from the backend.
Throws an ApiException if the metadata retrieval fails.
Implementation
Future<List<FileMetadata>> getDirectoryMetadata(String directoryPath) async {
assert(
directoryPath.endsWith('/'),
'$directoryPath is not a valid directory path, because it does not '
'end with a /');
return await _apiClient.get(
_metadataPath(directoryPath),
headers: _session.authenticationHeaders,
responseDeserializer: listOf(FileMetadata.fromJson),
);
}
