You can use Column widget and generate your desired UI elements , and through GestureDetector you can navigate your pages on those respective elements.

How to change the splashRadius of a BottomNavigationBarItem in Flutter

I am trying to change de splashRadius of a BottomNavigationBarItem in Flutter as if it was an IconButton but there isn't a variable that woks as splashRadius. Any help?
You have some styling options in the bar itself, but I don't think it has an option for what I think is a splashRadius. If not, you'll probably have to create a bottom navigationbar yourself. (You can take a look at different packages to see how they do it)
