Reproduce the repeated Flutter page navigation on the listed Xiaomi 8SE setup and inspect the stack trace around FlutterViewContainerManager.setContainerResult, ContainerRecord.onDestroy, and FlutterActivityAndFragmentDelegate.onDestroyView. Done means identifying and preventing the setContainerResult crash during activity destruction, with a regression check for returning to the page repeatedly.
