Building with React Native + Expo: The FlexNative UI Approach

The FlexNative UI is a collection of reusable components tailored for applications built with React Native and Expo. This project focuses on creating scalable and maintainable mobile applications by leveraging Expo's capabilities and React Native's flexibility.

You can find the official documentation about React Native + Expo here.

Key Versions

• Expo: ^52.0.11
• React Native: 0.76.3
• React: 18.3.1

These versions were chosen to ensure the project remains stable while taking advantage of the latest updates in the ecosystem.

Enhanced Performance

The project utilizes Expo Router (~4.0.9) to simplify navigation through a file-based routing system. This approach makes it easier to manage and organize screens within the app directory, ensuring scalability and maintainability.

The app Directory

The app directory serves as the backbone of the project, housing all screens and allowing for layout configurations to ensure consistent user interfaces. This setup prioritizes simplicity and modularity, enabling a clean structure that supports project growth.

Why This Setup Matters

• Reusability: Designed to facilitate the reuse of components across the application.
• Simplicity: Reduces complexity by adhering to best practices and leveraging Expo Router.
• Scalability: Provides a robust foundation that grows with the application's needs.

This document outlines the essential elements of the FlexNative UI, focusing on the integration of Expo and React Native for optimal development practices.
