About this project

flutter_unity_widget is a Flutter plugin that allows embedding Unity 3D content into Flutter applications, supporting Android, iPad OS, iOS, and Web. It enables bidirectional communication between Flutter and Unity, and can be used in fullscreen or embeddable modes. The plugin requires Flutter >= 3.16.0 and supports Unity versions from 2019.4.3 up to 2022.3.x, with recommended use of the latest 2022.3 LTS. It is not recommended for new projects; the author has evolved it into Game Framework, a next-generation successor with a CLI, Unreal Engine support, and cloud publishing. The README provides detailed setup instructions for Unity project configuration, exporting, and platform-specific steps for Android and iOS, including AR Foundation and Vuforia integration. It also covers emulator limitations and notes on Unity version requirements for publishing to Apple and Google stores. The package remains available for existing projects but is no longer the recommended starting point.
