Project Layout As A Way To Architecture Layers In Flutter

I have a need to have a specific flutter project structure for the apps I build to demo the paid Flutter UI Kits I am building and the Flutter demo apps I am building for my Flutter App Designer book series. And that happens to mirror the exact way one should use project layout to help architecture layers for a flutter app. Let me show you.

Using packages

And, it can also have and share assets. So I can use them in this way:

-Has the full domain layer with unit tests and is the first thing built of the app

2. Presentation (package)

-Contains the themes and custom widgets and only has unit tests but no goldens testing
