flutter_boost缓存问题

flutter: 2.2.1
flutter_boost: 3.0_preview5

iOS端（iPhone12 mini iOS15）flutter页面触发重启逻辑，重新设定rootViewcontroller后，再次跳转flutter页面时，页面跳转错误，重新回到了重启前的画面，且画面状态没有更新。

尝试解决：每次重启时，重新调用setup方法，重新生成新的engin。
上述解决方式，解决了跳转错误的问题，但会造成内存的增长，如多次反复操作，则会因内存问题造成闪退。

请问：
1.是否有其他方式能解决跳转错误问题？
2.engin是否能够清除缓存？

Reproduce the navigation and memory behavior on an iPhone 12 mini running iOS 15 with Flutter 2.2.1 and flutter_boost 3.0_preview5. Start by tracing the setup call, engine recreation, rootViewController reset, and subsequent Flutter-page navigation; done means navigation returns to the expected current state without unbounded memory growth.
