Implementation
Future<Uint8List> readBytes() async {
final Completer<List<int>> bytesFile = Completer<List<int>>();
final FileReader reader = FileReader();
reader.onLoad.listen(
(event) => bytesFile.complete(reader.result as FutureOr<List<int>>?));
reader.readAsArrayBuffer(this);
return Uint8List.fromList(await bytesFile.future);
}
