I finally started working on a React native app last week and to be honest I have been thinking of doing so since an year now, but always lacked the motivation to start. A few weeks back I was reading this book “The Subtle Art of Not Giving a F*ck” and I came across this quote which gave me a final push to start writing a React Native App. The quote is: Action isn’t just the effect of motivation; it’s also the cause of it. And with that thought, let’s begin. Intent This article is about how to have a custom component for header, bottom tab navigation when you are using and how to style it since it took me one complete day to figure out all of it! It really took a lot of research, google search and reading all the github solutions by others, of which some did work and some did not. React-Navigation Here is how the final screen with custom header and tab look like: The entire code can be found here and can be tested with . expo So lets begin 😄 Pre-Requisites We are using 0.55.2 version and 2.0.0 React Native React navigation Follow the getting started guide from here to create a new react native app from scratch and then create a routes file similar to the one mentioned below. _This page will help you install and build your first React Native app. If you already have React Native installed, you…_facebook.github.io Getting Started · React Native Alternatively you can also install package. create-react-native Your route file should look like the following gist: is a function that returns a React component. It takes and, optionally, [createStackNavigator](https://reactnavigation.org/docs/en/hello-react-navigation.html) a route configuration object an options object Approach In this section, I have put down all the FAQs about customizing the header.We will use the solution for each of them to create our customized header. How do I use a custom header for my React navigation?

Solution:- Use **headerStyle** How do I style my header title? Solution: Use **headerTitleStyle** How do I change the color of the back arrow? Solution: Use **headerTintColor** headerTintColor: “#fff” How do I hide the back arrow? Solution:- Use and set it to **headerLeft** **null** headerLeft: null What if I do not want to show a header for some screens? Solution: Set **header** to **null** header: null The final code after all the changes would look like this: That pretty much should solve most of the customization regarding custom header. Up next is if I am using a for bottom tab navigation, how do I style the header for tabs and the bottom navigation? TabNavigator With TabNavigation and Header, the process is slightly complicated.

Now inside of your , have code like this: **navigationOptions** **TabNavigator** Finally after all the changes, the tab router looks like this: Conclusion Hopefully this article saves someone’s time while getting started with React Native.
