Mi Barrio is a multi-vendor online mobile platform app that sells various things ranging from salon to clothing to electronics just to name a few. The app is currently serving in all major cities in Spain. The app has been built on Flutter platform. The most fascinating thing about Flutter is that the same codebase can be shared on both iOS and Android saving time, money and other resources. The app performs seamlessly on both platforms delivering cent percent output every time. The app has been built to handle large products, users and requests at a time and with a provision to incorporate more in the future: thanks to our developers.
