## Api

```dart

BadSocket.wrap(Socket socket, {

  int readLatency,

  int readLoss,

  int writeLatency,

  int writeLoss,

});

```

## Usage

Basic example:

```dart

import 'dart:io';

import 'package:bad_socket/bad_socket.dart';

main() async {

  // 1. Create a normal socket.

  Socket socket = await Socket.bind('0.0.0.0', 1234);

  // 2. Wrap it.

  Socket badSocket = BadSocket.warp(socket,

    writeLatency: 100,

    writeLoss: 0.15,

  );

  // 3. Write to this wrapped socket will take effect

  //    after 100 ms,

  //    and 15% of write calls will be discarded.

  badSocket.add([0xCA, 0xFE]);

}

```

A complete example:

```dart

import 'dart:io';

import 'package:bad_socket/bad_socket.dart';

Future startLocalEchoServer() async {

  final server = await ServerSocket.bind('0.0.0.0', 0);

  server.listen((socket) {

    final badSocket = BadSocket.wrap(

      socket,

      writeLatency: 100,

      writeLoss: 0.2,

    );

    badSocket.listen((data) {

      print('Server send: $data');

      badSocket.add(data);

      badSocket.flush();

    });

  });

  return server.port;

}

main() async {

  final port = await startLocalEchoServer();

  final client = await Socket.connect('127.0.0.1', port);

  client.listen((data) {

    print('Client recv: $data');

  });

  while (true) {

    final data = 'hello world'.runes.toList();

    data.shuffle();

    await Future.delayed(Duration(seconds: 1));

    print('Client send: $data');

    client.add(data);

    await client.flush();

  }

}

```
