Tá roinnt cur chuige bainistithe stáit ag Flutter — ó na cinn ionsuite (setState, InheritedWidget) go dtí leabharlanna coitianta (Provider, Riverpod, Bloc, GetX). Tuiscint a bheith agat ar na príomhroghanna, a ndearcadh, agus na malartuithe trádála cabhraithe dhuit an cur chuige ceart a roghnú do aip.
Cur chuige ionsuite
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 — simplí agus infheidhmithe
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
