How to set backgroundColor of tabbar when the borderRadius is given to it?

I want to set my tabBar of borderRadius 30 and set the backgroundColor of the tabBar, but the problem is that there is white color background in the tabBar even if I have set the backgroundColor to other color! How to resolve this?

tabBarOptions: {  showIcon: true,  showLabel: false,  activeTintColor: '#333645',  inactiveTintColor: 'grey',  style: {    backgroundColor: '#FEB6B9',    height: 50,    borderRadius: 30,    marginBottom: 10  }}
