这种应用进入后台长时间后进入flutter页面crash 怎么处理？

Start with FBFlutterViewContainer's surfaceUpdated: and viewDidAppear: entry points, using the reported Flutter 2.8.1 lifecycle sequence as the reproduction case. Confirm the long-background transition and determine what condition leads to the crash; done means the sequence no longer crashes when reopening the Flutter page after extended backgrounding.
