我在让 Flutter 与 Unity 一起工作方面遇到了非常困难的时期。 pub.dev 上的 xraph.com 有一个名为 flutter_unity_widget 的库，我正在努力使其工作。
规格：
Android，不使用模拟器/模拟器，仅使用我的真实/物理手机（Android v14 API 34 上的三星 Galaxy Z Fold 4）
Unity 2022.3.30f1。目前正在下载并试用 2022.2.0f1 作为当前的 fuw-XXXX.unitypackage 文件，可在 unitypackages 文件夹中找到。 “尝试使用最新的unitypackage。”是dev写的，github文件夹中的当前版本是fuw-2022.2.0、fuw-2022.1.7f1、fuw-2022.1.1-v2。版本与Unity版本相对应。

我遵循了主 github (https://github.com/juicycleff/flutter-unity-view-widget/tree/master) 以及 pub.dev () 上 Android 文档页面上的所有说明https://pub.dev/packages/flutter_unity_widget）和一堆 Youtube 视频教程和在线文章，这些教程和在线文章都执行了相互冲突的步骤，已经过时，并且不起作用。
当我尝试自己执行此操作，除了启动并显示它之外没有其他功能时，我收到以下错误消息，该消息无限重复，并且手机屏幕上没有显示任何内容。

在已知问题下，它说 Unity 在 Android 上冻结并崩溃，请使用 OpenGL3 作为图形 API。 我试过这样做，没有区别。
我手动停止那里的程序，因为“BufferQueue已被放弃”消息无限重复，并且屏幕上只是充满黄色的页面。
我也在 Github Issues 上问了这个问题，并从迄今为止为我工作的开发者 timbotimbo 那里得到了回复/解决方案。我将把这个留给其他有同样问题的人。
Github 问题页面上也有指向问题的链接，因此请查看：https://github.com/juicycleff/flutter-unity-view-widget/issues/985
“您遇到的这个问题是由 Flutter 3.19 中的错误引起的。 这应该在 Flutter 3.22 中得到修复。
如果您必须使用 Flutter 3.19，您唯一的选择是使用 useAndroidViewSurface: true 参数。这会将 Flutter 嵌入模式更改为不受此特定错误影响的替代方案。
如果您升级到 Flutter 3.24，则必须使用此问题中的解决方法，因为该版本需要对 pub.dev 上尚未提供的插件进行小修复。
对于 Unity 版本，请使用 2022.3.x 。" -timbotimbo
