How to Setup Environment Variables in React Native Expo

In this tutorial, you will learn how to set up environment variables in your React Native Expo project. Environment variables are an essential part of any software development project as they allow developers to store sensitive data such as API keys, database credentials, and other configuration variables outside of the codebase. This makes it easier to manage and secure the application's data.

In this video, we will cover how to create and manage environment variables in your React Native Expo project, including how to set them up in different development environments like local, staging, and production. We will also explore how to access these variables in your code and best practices for managing them.

Whether you are new to React Native Expo or a seasoned developer looking to improve your project's security and scalability, this tutorial will provide you with the tools you need to set up environment variables in your project with ease. Follow along with the step-by-step instructions and start improving your React Native Expo project today!

I know this way but how would u then set these environment variables values when u r bulding your app using EAS? Because i check the eas docs and it shows a totally different way for adding environektn varibales to the app
