Please consider using Flutter technology for the User, Seller, and Delivery App. We request the development of a Flutter-based user mobile app. Recently, we had the opportunity to review a demo of your React User App, accessible via this link: https://drive.google.com/file/d/16IkXLe521iFt5_lRHzm7K5P6d13ZdcXH/view React applications tend to exhibit slower performance compared to Flutter apps. This was evident in your React user app demo, despite optimization efforts. The performance and responsiveness of your React app are abysmal compared to other e-commerce solutions on CodeCanyon Because they are using Flutter technology. Given that MARTVILL's website is more developed than others on CodeCanyon, choosing a robust technology for mobile applications in 2024 is essential. Failure to do so may result in business closures due to technological shortcomings. Both you and your customers should adopt a long-term perspective on market trends. With a React App, achieving good ratings, feedback, and customer experience may be challenging. Therefore, we strongly advocate selecting superior technology such as Flutter for mobile applications. You can adjust the price of the Flutter app accordingly to cover development costs. We hope this recommendation is clear and understandable. Thanks
