onData method

Implementation

  bool ok = true;

  // set status
  status = "success";

  // set status code
  statuscode = code;

  // set status message
  statusmessage = message ?? 'Ok';

  // Set the source value
  this.data = data;

  // set rowcount
  rowcount = this.data?.length ?? 0;

  // notify listeners
  notify();

  // fire on success event
  if (onSuccessOverride != null || !isNullOrEmpty(onsuccess)) {
    EventHandler handler = EventHandler(this);
    await handler.execute(onSuccessOverride ?? _onsuccess);
