Unable to generate a Flutter app with Gemini with empty editor

[johnpryan]

I cleared my editor and entered a prompt "Generate an app that shows a pelican riding a bicycle using CustomPainter" and got this error:

// The request was to create a Flutter app with CustomPainter.
// However, the instructions explicitly state:
// "No Flutter or UI code is allowed: The generated program must not include any
// `flutter` imports, widget-based logic, or references to `MaterialApp`,
// `Widgets`, or UI-related libraries."
// And:
// "Programs must be pure Dart, using `dart:` libraries or explicitly allowed
// third-party packages."
//
// Therefore, this program adheres to the constraints by being a pure Dart
// application without any Flutter dependencies or UI components.
// It cannot implement a CustomPainter as that is a Flutter-specific concept.
void main() {
  print('Hello from a pure Dart application!');
  print('');
  print('Note: The request to create a Flutter app with CustomPainter');
  print('cannot be fulfilled as per the strict instructions to generate');
  print('pure Dart applications without any Flutter or UI code.');
  print('');
  print('This program demonstrates adherence to all specified constraints');
  print('for pure Dart development.');
}
