expo vector icons install with code examples

Expo Vector Icons is a popular package for adding customizable icons to your React Native projects. In this article, we will go over the steps to install and use the package in your Expo app, with code examples.

First, you will need to install the expo-vector-icons package in your project by running the following command in your project's root directory:

expo install expo-vector-icons

Once the package is installed, you can start using the icons in your app. To use an icon, you will need to import it from the package and use it as a component. For example, to use the "heart" icon, you can add the following code to your component:

import { Ionicons } from '@expo/vector-icons';

<Ionicons name="ios-heart" size={32} color="red" />

Here, we are importing the Ionicons icon set and using the "ios-heart" icon with a size of 32 and a color of red. You can also use other icon sets such as MaterialIcons and FontAwesome.

You can also customize the icon by passing props, for example:

<Ionicons
  name="ios-heart"
  size={32}
  color="red"
  style={{ marginRight: 10 }}
/>

In addition to using individual icons, you can also use the createIconSet function to create your own custom icon set. This allows you to use your own SVG or TTF files for the icons.

For example, you can create a custom icon set like this:

import { createIconSet } from '@expo/vector-icons';
import fontJson from './path/to/font.json';
const CustomIcon = createIconSet(fontJson, 'CustomIcon');

<CustomIcon name="custom-icon" size={32} color="black" />

In this example, we are importing the createIconSet function and using it to create a new custom icon set from a JSON file that contains the font information. We can then use the CustomIcon component to display the custom icon.

In conclusion, Expo Vector Icons is a great package for adding customizable icons to your React Native projects. With the ability to use pre-built icon sets or create your own custom set, it offers a lot of flexibility and ease of use. With the above steps and examples, you should have no problem getting started with using Expo Vector Icons in your own projects.

Another great feature of Expo Vector Icons is the ability to use icons as buttons. By using the TouchableOpacity component, you can make an icon act as a button that can perform an action when pressed. For example, you can create a heart button that allows a user to "like" a post by adding the following code:

import { Ionicons } from '@expo/vector-icons';
import { TouchableOpacity } from 'react-native';

<TouchableOpacity onPress={() => { console.log('Post liked!') }}>
  <Ionicons name="ios-heart" size={32} color="red" />
</TouchableOpacity>

In this example, we are wrapping the Ionicons component in a TouchableOpacity component. The onPress prop is added to the TouchableOpacity component and a callback function is provided that logs a message to the console when the button is pressed. You can replace the console.log with your own function to handle the action.

Another thing that can be done is to change the color of the icon when it is pressed, this could be achieved using the state and onPress events:

const [iconColor, setIconColor] = useState('black');

<TouchableOpacity 
  onPress={() => { 
    setIconColor('red');
    console.log('Post liked!') 
  }}
>
  <Ionicons name="ios-heart" size={32} color={iconColor} />
</TouchableOpacity>

It's also possible to use the icons in the tab navigation. The package @react-navigation/bottom-tabs provides a way to use icons in the tab navigation. For example, you can create a tab navigation with icons like this:

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

const Tab = createBottomTabNavigator();

function MyTabs() {
  return (
    <Tab.Navigator
      screenOptions={({ route }) => ({
        tabBarIcon: ({ focused, color, size }) => {
          let iconName;

          if (route.name === 'Home') {
            iconName = focused ? 'ios-home' : 'ios-home';
          } else if (route.name === 'Settings') {
            iconName = focused ? 'ios-settings' : 'ios-settings';
          }

          // You can return any component that you like here!
          return <Ionicons name={iconName} size={size} color={color} />;
        },
      })}
      tabBarOptions={{
        activeTintColor: 'tomato',
        inactiveTintColor: 'gray',
      }}
    >
      <Tab.Screen name="Home" component={HomeScreen} />
      <Tab.Screen name="Settings" component={SettingsScreen} />
    </Tab.Navigator>
  );
}

In this example, we are importing the createBottomTabNavigator function and using it to create a new Tab.Navigator component. The screenOptions prop is used to specify the icon for each tab, and the tabBarOptions prop is used to customize the appearance of the tab bar.
