SFTP Debug Log File Path

See more SFTP Examples

Demonstrates how to use the DebugLogFilePath property to get information if a Chilkat method crashes or hangs. Dart

import 'package:chilkat/chilkat.dart';

void main() {
  final sftp = CkSFtp();

  // Insert this code just before the method call that crashes or hangs.
  sftp.verboseLogging = true;
  sftp.debugLogFilePath = '/some/file/path/sftp_debug_log.txt';

  // Make the call that crashes or hangs,
  // for example, if the method is DownloadFileByName:

  final remoteFilePath = '...';
  final localFilePath = '...';

  // Note: If the method returns control to your application code, then it did not crash within Chilkat.
  // The DebugLogFilePath property causes all information that would be recorded in the LastErrorText to be emitted to the
  // log file (with immediate file write flushing, i.e. no buffering).  Thus, in a crash situation,
  // the log file will contain information up to the point of the crash.

  try {
    sftp.downloadFileByName(remoteFilePath, localFilePath);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }
}
