## Implementation

    String toString() {
      StringBuffer sb = new StringBuffer();
      sb.write("FileSystemException");
      if (message.isNotEmpty) {
        sb.write(": $message");
        if (path != null) {
          sb.write(", path = '$path'");
        }
        if (osError != null) {
          sb.write(" ($osError)");
        }
      } else if (osError != null) {
        sb.write(": $osError");
        if (path != null) {
          sb.write(", path = '$path'");
        }
      } else if (path != null) {
        sb.write(": $path");
      }
      return sb.toString();
    }
