if you are to use react-native-vector-icon is much easier, just create an array like the one i created below, for all the names of the icon you want to use and if you want to use image, then you will have to use image links because the last time i checked react native won't allow you to load static assets dynamically.
Benefit of using an icon especially react-native-vector-icon:
Access to tonnes of iconsets.
Styling based on if its focused or not.
....and others things i can't remember.
`

import Icon from 'react-native-vector-icons/Ionicons';
const styles = {
body: {
backgroundColor: '#3b4147',
height: 60,
},
tabWrapper: {
flexDirection: 'row',
justifyContent: 'center',
alignItems: 'center',
height: 50,
},
tabInnerWrapper: {
marginRight: 12,
marginLeft: 12,
justifyContent: 'center',
alignItems: 'center',
},
textStyle: {
fontSize: 12,
color: '#62666b',
},
focusTextStyle: {
fontSize: 12,
color: '#acafb1',
},
};
const {body, tabWrapper, tabInnerWrapper, textStyle, focusTextStyle} = styles;
const focusIconColor = '#acafb1';
const iconColor = '#62666b';
const IconNames = ['ios-compass-outline', 'ios-cut-outline', 'ios-chatboxes-outline'];
const IconNamesFocus = ['ios-compass', 'ios-cut', 'ios-chatboxes'];
const CustomTabBar = ({ navigation: { state, navigate }}) => {
const { routes } = state;
return (
<View style={body}>
<View style={tabWrapper}>
{routes && routes.map((route, index) => {
const focused = index === state.index;
return (
<TouchableOpacity
key={route.key}
onPress={() => navigate(route.routeName)}
style={tabInnerWrapper}
>
<Icon
name={focused ? IconNamesFocus[index] : IconNames[index]}
size={25}
color={focused ? focusIconColor : iconColor}
/>
<Text style={focused ? focusTextStyle : textStyle}>
{route.routeName}
</Text>
</TouchableOpacity>
);
})}
</View>
</View>
);
};
