[Feature Request] is there will have a sample example of an architecture for modular design of large projects in PyQt? 

Excuse me, is there will have a sample example of an architecture for modular design of large projects in PyQt? 
For example, Flutter has the following [modular design scheme](https://github.com/aka-zoe/flutter_module_sample). Is there a similar sample scheme for PyQt that can be used for reference?
