将原先在initState中进行的初始化，改放到确保Overlay被mounted之后的时序中

这单纯就是Boost框架的问题吧，和initRoute也没关系，只是对MaterialApp中设置了locale后没做好兼容的问题。 而且为什么会有内部关键逻辑理解产生问题？关键逻辑没变吧，一直都是启动时获取已经挂载的Overlay然后做后续初始化，现在的PR也只是确保初始化时Overlay一定被挂载了。 |

@joechan-cq 这边建议可以自行拉分支修复～～主仓库暂不考虑修复哈 |
我混合项目使用了flutter_screenutil，也是必白屏，去掉就不会了 |
如果报错也是一样的，那原因应该也一样，screenutil的build方法，内部有延迟挂载的逻辑。 |
