Android iOS app with flutter for WoWonder script

I am interested in developing an Android and iOS application using the Flutter framework to support a WoWonder script. The project will require integrating any relevant existing APIs, although I have not yet determined which ones will be necessary. Additionally, I am not sure about the design preferences at this stage and will need to discuss this further with the developer.

Furthermore, I require the application to have social login functionality, including Facebook, Google, and Apple for iOS.
