iOS14系统触发微信分享之后, 再从微信返回app会卡在启动页1分钟,再恢复到app的之前页面

flutter_boost: ^1.12.13+3
iOS原生工程混合接入Flutter页面, 从flutter页面发送事件给原生, 原生在调取微信分享, 到微信之后, 点击取消分享再回到app, 这个时候app不是显示最后的页面, 而是显示启动页卡主1分钟左右在显示原来的flutter页面.
麻烦有空帮忙看看, 谢谢

Reproduce the issue in a hybrid native iOS app using flutter_boost 1.12.13+3: send an event from a Flutter page, invoke WeChat sharing, cancel it, and return to the app. Trace the app lifecycle and Flutter page restoration around the iOS 14 return; done means the previous Flutter page reappears without remaining on the launch screen for about a minute.
