Fixing the Blank Screen Issue in Your React Native App: A Step-by-Step Guide

If you are a React Native developer, you might sometimes encounter frustrating situations where your app builds successfully, yet it displays a blank screen with no errors in the console. This is particularly common after configuring your navigation system. In this post, we’ll explore the causes of this problem and provide a clear, structured solution to get your app running smoothly again.

Understanding the Problem

The blank screen issue often arises due to improper return statements in your components, especially when setting up navigation. In the scenario presented, the developer has installed React Navigation and set up their Navigation component, but the screen remains blank after the app is built.

Key Symptoms of the Blank Screen Issue:

The app builds without displaying any error messages in the console.

The intended screen content does not render, resulting in a blank interface.

Step 1: Modify Your Navigation.js File

The first step is to change the way the Navigation component is structured. Here's the corrected version of the Navigation.js code:
