                title:'',
                tabBarIcon: ({ tintColor }) => {
                    return (
                        <IconIonicons
                            name='ios-notifications'
                            size={40}
                            color={tintColor}
                        />
                    );
                },

You can use SwitchNavigator of React Navigation. As the SwitchNavigator is to only ever show one screen at a time. By default, it does not handle back actions and it resets routes to their default state when you switch away.

Kindly refer this https://reactnavigation.org/docs/en/switch-navigator.html

Remove the **Splash** Screen from your **StackHome** StackNavigator
Alter your **RootNav** with Switch Navigator like below

// Uses SwitchNavigator
const RootNav = createSwitchNavigator({
    StackHome:{
      screen: StackHome
    },
    Splash:{
        screen: Splash
    },Login:{
        screen: Login
    },
},{
        initialRouteName : 'Splash'
});

Your StackHome consist of some stack navigators screens, you can set the navigation options from there itself to set the image in the header. You can set like below.

const StackHome = createStackNavigator({
    CardView:{
        screen: CardView,
        navigationOptions: ({ navigation }) => ({
            headerTitleStyle: { flex: 1, fontWeight: 'normal', fontSize: 15, color: '#FFFFFF', fontFamily: 'DroidSans-Bold' },
            headerTintColor: "#2662b2",
            headerStyle: {
                backgroundColor: "#05BFFF",
            },
            headerRight:(<View><NotificationComponent navigation={navigation}/></View>)            
        })
    },
    Thumb:{
        screen: Thumb,
    },  Item:{
        screen: Item,
    }
});
