Flutter में कई state management दृष्टिकोण हैं — built-in (setState, InheritedWidget) से लेकर लोकप्रिय libraries (Provider, Riverpod, Bloc, GetX) तक। मुख्य विकल्पों, उनके दर्शन, और trade-offs को समझना किसी app के लिए सही दृष्टिकोण चुनने में मदद करता है।
Built-in दृष्टिकोण
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 — सरल और अनुशंसित
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
