The Marketplace Mobile App is a cross-platform solution that connects buyers and sellers in a user-friendly mobile environment. Built with Flutter and powered by Firebase, this application provides real-time updates, instant messaging, and secure transactions for users looking to buy or sell products locally or internationally.
The app features an intuitive interface that makes listing items for sale as simple as taking a photo and adding details. For buyers, the search and filter functionality allows them to quickly find what they're looking for and connect with sellers through the built-in messaging system.
One of the main challenges was creating a responsive and smooth user interface that worked consistently across both iOS and Android platforms. Flutter's widget system provided the flexibility needed to create custom UI components that maintained native feel on both operating systems.
Another challenge was implementing real-time messaging and notifications. Firebase Cloud Messaging and Firestore were utilized to create a reliable and scalable real-time communication system that could handle thousands of concurrent users without performance degradation.
Ensuring secure payments required implementing proper encryption and working with established payment gateways. The solution incorporated multiple layers of security while maintaining a seamless checkout experience for users.
