Flutter मा धेरै state management दृष्टिकोण छन् — built-in (setState, InheritedWidget) देखि लोकप्रिय लाइब्रेरी (Provider, Riverpod, Bloc, GetX) सम्म। मुख्य विकल्पहरू, तिनीहरूको दर्शन, र trade-offs बुझ्नु एप्लिकेशनको लागि सही दृष्टिकोण छनोट गर्न मदत गर्छ।
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 र सुझाएको
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
