AgroU App-dev

I need a highly skilled team to help me develop an app for both iOS and Android platforms using firebase. It's a simple app that allows user to post on a feed list their products and follow others users I have a clear idea of the specific functionalities and features that I would like the app to contain, and I have already done the UI/UX design and began some development in flutterflow. The successful development of this app should provide a premium result and quality user experience. It is imperative that the development team have an excellent understanding of iOS and Android device architecture, so that the app is able to work across both platforms seamlessly. Previous experience in developing similar cross-platform apps is preferable.
