Implementation

@override

void onError(FlutterErrorDetails details) {
  // Don't call this routine within itself.
  if (_inError) {
    return;
  }

  // If it involves the widgets library,
  // call the latest SateX object's error routine
  // Possibly the error occurred there.

      // Include it in the error reporting as well.

  super.onError(details);

  // Always test if there was an error in the error handler
  // Include it in the error reporting as well.
