Creating split OTP input fields in React Native

React Native developers often face challenges when creating authentication flows that require a one-time password (OTP), particularly when managing TextInput components. This guide provides a detailed walkthrough on building split OTP input fields in React Native without relying on external packages. It involves setting up the development environment using Expo CLI, creating a TextInput component that serves as the source of truth, and implementing styled components for split input boxes. The tutorial also covers highlighting the current OTP digit, adding dynamic elements with useEffect, hiding the keyboard when pressing outside the boxes, and integrating a submit button that syncs with the OTP input state. The guide demonstrates these features with code examples and explains how to adjust them for various use cases, such as altering the number of required digits.
