Flutter’s widget-based structure makes UI design simple. Widgets in Flutter are the constructing blocks for creating interactive person interfaces, every with its personal properties and behaviors.

StatelessWidget is used when a widget’s configuration doesn’t rely upon mutable state saved within the widget itself. Use StatelessWidget for purely declarative, configuration-driven UI; when the UI must react to ephemeral, native adjustments (for instance, animation controllers, focus nodes, or native counters), use StatefulWidget or an exterior state supervisor.

StatefulWidget holds mutable state that impacts the widget’s look or conduct and might name setState to rebuild. For small, native UI state, setState inside a StatefulWidget is ok. For app-level state or complicated flows, choose an exterior state-management answer comparable to Supplier, Riverpod, or Bloc to maintain logic testable and scale back pointless rebuilds.

Flutter provides a wide range of structure widgets for arranging UI components. Primary widgets like Row, Column, and Container assist arrange and place components horizontally and vertically. For extra superior layouts, Stack permits you to layer components, ListView creates scrollable lists, and CustomPaint permits you to create customized graphics. This flexibility empowers builders to design every thing from easy interfaces to complicated, interactive UIs.

This widget-centric strategy simplifies UI growth by making elements composable and reusable, saving builders time when constructing scalable apps.
