I'm new at FlutterFlow. I'm willing to read / view videos on the subject of creating an Android prototype app using FlutterFlow, but I don't know where to start. I don't want to find out that what I want is impossible with FlutterFlow. I want to know how to build an app for Android - a really minimal app will do - and if I can load the app on my Samsung Galaxy Android tablet computer device without having to put it in the Google App Store. Eventually I will need to know how to put the app in the Google App Store. Please share a) your thoughts; b) some pointers toward documentation and c) some pointers toward video resources for that I need.
