Resolving Text Visibility Issues in React Native for iOS and Android

Creating applications with React Native can sometimes lead to unexpected challenges, especially when it comes to displaying text on different platforms like iOS and Android. Many developers encounter situations where text appears correctly in a web view but fails to show up on mobile devices.

In this guide, we’ll explore a common issue faced by developers working with React Native: not being able to see text on the HomeScreen for iOS and Android. We’ll outline the steps to resolve this problem, ensuring your application is fully functional across platforms.
