Receive a Block of Bytes to a File

See more Socket/SSL/TLS Examples

Demonstrates Socket.ReceiveBytesToFile, which receives one available block of bytes and appends it to a file.

The file path is relative to the application's current working directory. An absolute path may also be used. Supply the path appropriate to your own environment.

import 'package:chilkat/chilkat.dart';

void main() {
  final socket = CkSocket();

  // Connect to the server using TLS.
  final bTls = true;
  final maxWaitMs = 5000;
  try {
    socket.connect('example.com', 5000, bTls, maxWaitMs);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // The file path is relative to the application's current working directory.  An absolute path
  // may also be used.  Supply the path appropriate to your own environment.

  // Receive one available block of bytes and append it to a file.  If bytes are already buffered,
  // they are used first; otherwise a single receive operation is performed.
  try {
    socket.receiveBytesToFile('qa_output/received.dat');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  print('Received block appended to the file.');
