I will provide you with a Flutter application, which will can be converted to an iOS app, Android app and webapp, without having to do much more work (depending on the specifics of the app). The app will satisfy the requirements you set forth at the beginning of our collaboration.

Wireframe: I first create a wireframe depending on your requirements. Prototype: Once approved, I move on to the Figma design. I add life to the wireframe. Development: Once approved, I begin creating the application, according to the vision you have approved. Delivery: I deliver the final product, meeting expectations.
