如何在Dart中通过套接字发送文件

Question

I am trying to send a binary file like image or pdf over a socket. I have tried following:

   file.readAsBytesSync().forEach((f) {
     socket.write(f);
   });

And

   socket.write(file.readAsBytesSync());

But I receive a list of integers instead of a binary file. Code given below in JAVA works fine and receiving port gets file in correct format

DataOutputStream dos = new DataOutputStream(s.getOutputStream());
FileInputStream fis = new FileInputStream(file);
byte[] buffer = new byte[4096];

while (fis.read(buffer) > 0) {
    dos.write(buffer);
}

fis.close();
dos.close();

I am trying to figure out what would be Dart equivalent of above java code.

Thanks in advance.

Correct code:

Socket s = await Socket.connect(host, port);
await s.addStream(file.openRead());
print("ok: data written");
