原生接入flutter得module和framework冲突问题

按照文档接入flutter module 没有问题，但后面接入一个第三方的SDK使用的flutter做的framework，再接入他们的framework后，导致原生跳转flutter无响应。

The issue names Flutter module integration, a third-party Flutter framework, and native-to-Flutter navigation, but no files or tests. Start by reproducing the documented module setup with the third-party framework and trace why native navigation becomes unresponsive; done means both integrations coexist and native navigation reaches Flutter.
