React Native Vector Icons

Install Package

$ npm install --save react-native-vector-icons

then link it

$ cd android && ./gradlew clean && cd ..
$ cd ios && pod install && cd ..

on iOS, go to ios/PROJECTNAME/Info.plist add this under ~UIAppFonts~

  <key>UIAppFonts</key>
  <array>
    <string>AntDesign.ttf</string>
    <string>Entypo.ttf</string>
    <string>EvilIcons.ttf</string>
    <string>Feather.ttf</string>
    <string>FontAwesome.ttf</string>
    <string>FontAwesome5_Brands.ttf</string>
    <string>FontAwesome5_Regular.ttf</string>
    <string>FontAwesome5_Solid.ttf</string>
    <string>Fontisto.ttf</string>
    <string>Foundation.ttf</string>
    <string>Ionicons.ttf</string>
    <string>MaterialIcons.ttf</string>
    <string>MaterialCommunityIcons.ttf</string>
    <string>SimpleLineIcons.ttf</string>
    <string>Octicons.ttf</string>
    <string>Zocial.ttf</string>
  </array>

on Android we need add some text too, go to android/app/build.gradle under ~apply from: "../../node_modules/react-native/react.gradle"~

apply from: "../../node_modules/react-native-vector-icons/fonts.gradle"

Now you can use it like this

import { createBottomTabNavigator } from '@react-navigation/bottom-tabs';
import MaterialCommunityIcons from 'react-native-vector-icons/MaterialCommunityIcons';

const Tab = createBottomTabNavigator();

function MyTabs() {
  return (
    <Tab.Navigator
      initialRouteName="Feed"
      tabBarOptions={{
        activeTintColor: '#e91e63',
      }}
    >
      <Tab.Screen
        name="Feed"
        component={Feed}
        options={{
          tabBarLabel: 'Home',
          tabBarIcon: ({ color, size }) => (
            <MaterialCommunityIcons name="home" color={color} size={size} />
          ),
        }}
      />
      <Tab.Screen
        name="Notifications"
        component={Notifications}
        options={{
          tabBarLabel: 'Updates',
          tabBarIcon: ({ color, size }) => (
            <MaterialCommunityIcons name="bell" color={color} size={size} />
          ),
          tabBarBadge: 3,
        }}
      />
      <Tab.Screen
        name="Profile"
        component={Profile}
        options={{
          tabBarLabel: 'Profile',
          tabBarIcon: ({ color, size }) => (
            <MaterialCommunityIcons name="account" color={color} size={size} />
          ),
        }}
      />
    </Tab.Navigator>
  );
}
