factory ReplayFileSystem({
@required Directory recording,
}) {
String dirname = recording.path;
String path = recording.fileSystem.path.join(dirname, kManifestName);
File manifestFile = recording.fileSystem.file(path);
if (!manifestFile.existsSync()) {
throw new ArgumentError('Not a valid recording directory: $dirname');
}
List<Map<String, dynamic>> manifest = new JsonDecoder()
.convert(manifestFile.readAsStringSync())
.cast<Map<String, dynamic>>();
return new ReplayFileSystemImpl(recording, manifest);
