Flutter tiene varios enfoques de gestión de estado — desde los integrados (setState, InheritedWidget) hasta bibliotecas populares (Provider, Riverpod, Bloc, GetX). Comprender las opciones principales, sus filosofías y compensaciones ayuda a elegir el enfoque adecuado para una aplicación.
Enfoques integrados
setState → local state in a StatefulWidget (simple; doesn't scale to shared state)
InheritedWidget → built-in way to share state down the tree (the foundation many
libraries build on; verbose to use directly)
Provider — simple y recomendado
PROVIDER → official-recommended, built on InheritedWidget; simple, widely used:
→ provide state at a point in the tree; descendants "watch"/consume it
→ ChangeNotifier holds state and notifies listeners → UI rebuilds on change
→ good for many apps; gentle learning curve
