Description

当对renderer做二次封装时，会出现如下warnning： image

初步判定PageRenderer调用getDerivedStateFromProps方法时，excuteLifeCycleMethod返回了undefined，而不是一个空值null，导致static方法getDerivedStateFromProps报错。

Contributor guide

Research direction
Investigate why executeLifeCycleMethod returns undefined instead of null when called from getDerivedStateFromProps in PageRenderer. Check the condition that leads to the undefined return and ensure it falls back to null.
