如何在我的应用栏上方（z-index）显示我的小吃店？

Question

I have this snack bar, it works perfectly, but it displays under a headerBar. Sometimes, I have to scroll up to see it. User will missed the important alert message, and don't know what is going on. I'm hoping to display it on top of all other components.

Overriding the z-index seems to work fine.

 .v-snack{ z-index: 99;important; }
