Need to build a flutter app

I am in need of a freelancer to help me build a mobile application using Flutter. I do not have the designs and assets ready yet, nor do I have an existing codebase; this is a fresh start. I need help creating designs and developing the entire application from scratch. If you have extensive knowledge with the Flutter framework and mobile app development, I look forward to working with you on this project.
