The React Native Chat App was developed to provide a mobile-friendly chat interface with the ability to send messages, images, and share location. The process started by setting up the development environment with React Native, Expo, and Firebase for data storage. I implemented a user interface where users could enter their names and choose a background color for the chat. The core functionality, using Gifted Chat, was developed for messaging, with additional features to share images and location using device APIs. I ensured offline message storage with Firebase for uninterrupted access to past conversations. Accessibility was prioritized by making the app compatible with screen readers for visually impaired users. I used Expo for easier development and testing across platforms (Android and iOS) and made sure the app worked seamlessly on both Android Emulators and iOS Simulators. The app is scalable with Firebase's real-time database for storing messages, ensuring both online and offline data availability.
