我也遇到了。 flutter 3.0.4 boost v3.0-null-safety-release.2.1 idlefish/flutterboost/containers/FlutterTextureHooker.java:62: 错误: 无法将类 FlutterRenderer中的方法 startRenderingToSurface应用到给定类型; flutterRenderer.startRenderingToSurface(surface); 错误: 不兼容的类型: Activity无法转换为ExclusiveAppComponent getFlutterEngine().getActivityControlSurface().attachToActivity(getActivity(), getLifecycle())

我也遇到了这个问题， `flutter_boost/src/boost_lifecycle_binding.dart:96` `════════ Exception caught by services library ══════════════════════════════════ 'package:flutter_boost[/src/boost_lifecycle_binding.dart]()': Failed assertion: line 96 pos 12: 'container != null': is not true. package:flutter_boost/src/boost_lifecycle_binding.dart:96 ════════════════════════════════════════════════════════════════════════════════`

看看是不是有一个页面仍存在，没有消失，只不过因为设置了透明看不到而已。这种情况可以先试试设置别透明，操作一下，看看啥情况。
