Adding a Filter Icon to Your Navigation Header in React Native

When developing applications in React Native, enhancing user experience often involves customizing navigation headers. One common requirement is to add icons that can serve various functionalities—like a filter icon to allow users to sort or filter content easily. Here’s how to do it effectively.

Problem: Adding an Icon in the Header

You may encounter challenges when trying to add an icon to the navigation header. For instance, you might get an error saying, "object is not a function." This usually happens if the icon component is not properly rendered or imported.

In this guide, we'll guide you through adding a filter icon using the MaterialCommunityIcons library and ensure that your navigation header looks polished and functional.

Solution: Step-by-Step Guide

Below, we'll break down the steps needed to add a filter icon to your navigation header using modern React Navigation libraries.

Step 1: Install Necessary Libraries

First, ensure you have react-native-vector-icons installed so you can use MaterialCommunityIcons. Run this command in your project directory:

Header Customization:

In the Home screen options, we define headerRight to render the filter icon with necessary properties such as size.

Step 4: Consider Handling Press Action

You might want to handle the icon's press event to trigger a filter action. Update the headerRight like this:
