Functional programming with Flutter

[SimonLab]

While reviewing the OOP concepts in Dart ( I'm looking at async/await with shared preference and how to use it with classes https://github.com/dwyl/flutter-todo-list-tutorial/issues/18 ) I was wondering if we could simplify a Flutter code by Applying functional programming concepts with Flutter: https://buildflutter.com/functional-programming-with-flutter/

@SimonLab if we can make the code as functional as possible we should. But I suspect there will still be a fair amount of OOP in form of inheritance from base widgets. 💭
