# Supertonic Flutter Example This example demonstrates how to use Supertonic 2 in a Flutter application using ONNX Runtime. > **Note:** This project uses the `flutter_onnxruntime` package ([https://pub.dev/packages/flutter_onnxruntime](https://pub.dev/packages/flutter_onnxruntime)). At the moment, only the macOS platform has been tested. Although the flutter_onnxruntime package supports several other platforms, they have not been tested in this project yet and may require additional verification. ## 📰 Update News **2026.01.06** - 🎉 **Supertonic 2** released with multilingual support!
