React Navigation - conditional hide item in bottom navigation bar

How to hide one of the item in the react-navigation bottom navigation bar based on some condition

For Example : this.state.show == true

So far i had tried as below

const Main = createBottomTabNavigator(
{
  Home: {screen: HomeStack},
  CheckInOut:  this.state.show ? {screen: CheckStack} : null ,
  Attendance: {screen: AttendanceStack},
  Profile: {screen: ProfileStack},
},
