### 请说明如何操作会遇到上述问题

使用阿里云arms性能监控，可定位相关问题。

### 在下面填入关键复现代码

使用方法与demo一致。

### 复现的平台

Both

### Flutter SDK版本

flutter-ohos-3.7.12-1.1.4

### FlutterBoost版本

4.6.5

### 是否延迟初始化FlutterBoost

No

### 解决方案

无

Start with src/main/ets/components/containers/FlutterBoostEntry.ts, especially aboutToDisappear, onContainerDestroy, detachFromEngineIfNeeded, and performDetach. Trace the related calls in src/main/ets/view/FlutterView.ts and the router files, then reproduce the reported HarmonyOS main-thread stall during container destruction. Done means the reported stall is resolved or its responsible entry point is demonstrated with a regression test or reproducible measurement.
