Installation:

To install the React Native Vector Icon library, you will need to create your React project and set up the file, to begin with, the coding. After this, write the following command in the command window of the project folder. If you need any help, try search for top react js development company for further assistance.

Npm install react-native-vector-icons –save .
Enter fullscreen mode Exit fullscreen mode

The above code will install the required dependencies for the React library into your device folder. The save keyword is used for updating the React Native Vector Icon library form the package.json. Hence it is not mandatory to be written.

In the higher versions of React(form 0.60), the linking of the library is done automatically by react. Do you not need to link unless you are using a lower version of React. To link the library, use the below-mentioned code;

react-native link react-native-vector-icons
Enter fullscreen mode Exit fullscreen mode

Configuration of the Icon Component:

In the icon Component, you can make your own ions or can use one from the icon library. With the icon component, you are able to import as many as the icon you desire to include in your React project. The structure of the icon component is as follows:

import Icon from 'react-native-vector-icons/FontAwesome'; 
const myIcon = <Icon name="rocket" size={30} color="#900" />;
Enter fullscreen mode Exit fullscreen mode

This component will import the Rocket icon in your project, and the size and colour properties will be applied to it. In addition to the above colour and size stylizing properties, there are several more. React Native Vector Icon library allows you to experiment with a large collection of properties with your icons. They are as follows:

  1. backgroundColor
  2. borderWidth.
  3. borderColor
  4. border-radius.
  5. Padding.
  6. Margin.
  7. colour
  8. fontSize.

Creating an icon button component:

In the react Native vector Icon library you can choose from a vast collection of icons that can be linked to an address. These vector icons can also act as buttons for performing a task, on click. An example for this operation is depicted below:

import Icon from 'react-native-vector-icons/FontAwesome';
const myButton = (
  <Icon.Button
    name="facebook"
    backgroundColor="#3b5998"
    onPress={this.loginWithFacebook}
  >
   Login with Facebook
  </Icon.Button>
);

const customTextButton = (
  <Icon.Button name="facebook" backgroundColor="#3b5998">
    <Text style={{ fontFamily: 'Arial', fontSize: 15 }}>
      Login with Facebook
    </Text>
  </Icon.Button>
);
Enter fullscreen mode Exit fullscreen mode

The above program is designing a button for Facebook. This button takes you to the Facebook login page after you click on the icon. In the icon.button component, the icon type is specified, and the function type is written. After that, formatting is done for an icon; it includes text in the icon and its font styles and color.

The react native vector icon library also consists of Ionicons. These icons are capable of carrying out material and IOS specific designs. For using these icons, a specific convention has to be followed. Here prefixes like ios- and md- are used to integrate them into a certain platform. With these prefixes, you can import icons that are used in a specific platform like android or IOS.

For instance, you want to insert an add icon from the IOS platform for that you should use ios- prefix in the name of the icon. The below component explains the code.

import Icon from "react-native-vector-icons/Ionicons"; 

// ...
<Icon
 name="ios-add"
 color="#ccc"
 size={25}
/>
Enter fullscreen mode Exit fullscreen mode

You can do this work more efficiently by enabling the automatic naming of the icon according to the platform. To do this, you can use the React native Platform module, where you can target a specific platform. After this, all your names will be written in the version of the chosen platform.

import { Platform } from "react-native";
import Icon from "react-native-vector-icons/Ionicons";

// ...
<Icon
 name={Platform.OS === "ios" ? "ios-add" : "md-add"}
 color="#ccc"
 size={25}
/>
Enter fullscreen mode Exit fullscreen mode
