Usage

An example:

import 'package:torrent_parser/torrent_parser.dart';

main() async {
  final parser = await TorrentParser.fromFile('test/multi.torrent');
  // or final parser = TorrentParser.fromString('d8:announce27:http://example.com/announcee');

  final torrent = parser.parse();
  // or final torrent = parser.tryParse();
  // which return null rather than throw an exception on failure

  print(torrent);
