This library provides classes to encode/decode bencoded bytes.

Mainly used to implement bittorrent related functions.

## Features

- Decode/encode bencoded bytes.

## Usage

Example:

```dart

import 'dart:typed_data';

import 'package:bencode/bencode.dart';

main() async {

  var decoded = bDecoder.convertString('d5:hello5:worlde');

  // or final decoded = bDecoder.convert('d5:hello5:worlde'.runes.toString());

  print(decoded);

  // Output: {hello: world}

  print(decoded is Map);

  // Output: true

  decoded = bDecoder.convertString('i123e');

  print(decoded);

  // Output: 123

  print(decoded is int);

  // Output: true

  decoded = bDecoder.convertString('li123ei123ee');

  print(decoded);

  // Output: [123, 123]

  print(decoded is List);

  // Output: true

  decoded = bDecoder.convertString('11:hello world');

  print(decoded);

  // bencoded strings are converted to bytes by default.

  // Output: [104, 101, 108, 108, 111, 32, 119, 111, 114, 108, 100]

  print(String.fromCharCodes(decoded));

  // Output: hello world

  print(decoded is List);

  // Output: true

  var encoded = bEncoder.convert({'hello': 'world'});

  print(encoded);

  // Output: [100, 53, 58, 104, 101, 108, 108, 111, 53, 58, 119, 111, 114, 108, 100, 101]

  print(String.fromCharCodes(encoded));

  // Output: d5:hello5:worlde

  encoded = bEncoder.convert(123);

  print(String.fromCharCodes(encoded));

  // Output: i123e

  encoded = bEncoder.convert([123, 456]);

  print(String.fromCharCodes(encoded));

  // Output: li123ei456ee

  encoded = bEncoder.convert(Uint8List.fromList([123, 123]));

  print(encoded);

  // Output: [50, 58, 123, 123]

  print(String.fromCharCodes(encoded));

  // Output: 2:{{

}

```

Decode bittorrent files:

```dart

import 'dart:io';

import 'package:bencode/bencode.dart';

main() async {

  final data = File('test/multi.torrent').readAsBytesSync();

  final decoded = bDecoder.convert(data);

  print(decoded.keys);

  // Output: (announce, announce-list, created by, creation date, encoding, info)

}

```

## Tests

Run tests:

```

pub run test

```
