Icons not showing on Tab Navigator with React Native - react-native

Question

I am having problems to show Icons using createBottomTabNavigator. I am using react-native-ionicons, and it works fine if I put any kind of Icon in the code, but is not showing on the tab bar. I already set showIcon: true.
Here is the code I am trying:
import React from 'react';
import {View, Text} from 'react-native';
import { createBottomTabNavigator, createAppContainer } from 'react-navigation';
import HomeScreen from './screens/HomepageScreen';
class SettingsScreen extends React.Component {
render() {
return (
<View style={{ flex: 1, justifyContent: 'center', alignItems: 'center' }}>
<Text>Settings!</Text>
</View>
);
}
}
const BottomNavigation = createBottomTabNavigator(
{
Home: HomeScreen,
Settings: SettingsScreen,
},
{
tabBarOptions: {
inactiveTintColor: 'gray',
swipeEnabled: true,
showLabel: true,
showIcon: true
},
}
);
export default createAppContainer(BottomNavigation);
Where HomepageScreen.js:
import React from 'react';
import {View, Text, Image, ScrollView} from 'react-native';
import {Card, CardItem, Right, Left} from 'native-base';
import {Header} from 'react-native-elements';
import Icon from 'react-native-ionicons'
class HomeScreen extends React.Component {
state = {
news: []
}
static navigationOptions = {
title: 'Noticias',
tabBarIcon: ({tintColor}) => {
<Icon style={{width: 10, height: 10, color: 'black'}} ios="ios-add" android="md-add" />
}
}
render() {
return (
//code
);
}
}
export default HomeScreen;
Am I missing something?

Answer 1

the size was probably too small, and you need to put color={tintColor} if you're going to put tintColor to use
import React from 'react';
import {View, Text, Image, ScrollView} from 'react-native';
import {Card, CardItem, Right, Left} from 'native-base';
import {Header} from 'react-native-elements';
import Icon from 'react-native-ionicons'
class HomeScreen extends React.Component {
static navigationOptions = {
title: 'Noticias',
tabBarIcon: ({tintColor}) => {
<Icon color={tintColor} ios="ios-add" android="md-add" />
}
}
render() {
return (
//code
);
}
}
export default HomeScreen;
hope it helps!
