Scaffold extendBody not working with bottomNavigationBar

[JasonHao123]

I'm using SnakeNavigationBar, set padding to make it floating, but the body is not stretch to fill the space under bottom navigation.

我在用SnakeNavigationBar，当设定了Padding使导航按钮向上漂浮，页面没有扩展到导航按钮下方区域。

After encapsulate Scaffold into SafeArea, it works.
