Flutter is a UI toolkit that offers: 1) Single codebase for multiple platforms (iOS, Android, Web, Desktop), 2) Widget-based development with rich customizable components, 3) Hot Reload for rapid development, 4) Direct compilation to native code without bridge, 5) Built-in Material Design and Cupertino widgets, 6) High performance with Skia rendering engine, 7) Complete development and debugging tools, 8) Strong community and package ecosystem.
Key differences include: 1) StatelessWidget is immutable and cannot change its state after creation, 2) StatefulWidget maintains mutable state with a separate State object, 3) StatelessWidget rebuild only when parent widget changes, 4) StatefulWidget can rebuild when setState() is called, 5) StatelessWidget is more memory efficient, 6) StatefulWidget is used for user interaction and dynamic content, 7) StatelessWidget is used for static content, 8) State persistence across rebuilds in StatefulWidget.
Key layout widgets: 1) Container for styling and positioning, 2) Row and Column for linear layouts, 3) Stack for overlapping elements, 4) Expanded and Flexible for responsive sizing, 5) GridView for grid layouts, 6) ListView for scrollable lists, 7) Wrap for flow layouts, 8) Custom SingleChildScrollView for scrollable content. Usage depends on layout requirements and content organization needs.
Key differences: 1) Container allows decoration and padding, 2) SizedBox is more lightweight and efficient, 3) Container can have multiple children through child property, 4) SizedBox primarily for dimensional constraints, 5) Container supports margin and alignment, 6) SizedBox for fixed dimensions, 7) Container for styling purposes, 8) SizedBox for space creation.
Button types include: 1) ElevatedButton for raised buttons, 2) TextButton for flat buttons, 3) OutlinedButton for outlined style, 4) IconButton for icon-only buttons, 5) FloatingActionButton for floating actions, 6) PopupMenuButton for menus, 7) DropdownButton for selections, 8) Custom button implementations.

Key differences include: 1) const is compile-time constant, final is runtime constant, 2) const requires all values to be known at compile time, 3) final can be set once at runtime, 4) const objects are canonicalized, 5) const constructors create immutable objects, 6) final allows for lazy initialization, 7) const improves performance for widgets, 8) final is used for runtime-dependent values.
Asset management includes: 1) pubspec.yaml configuration, 2) Asset bundling process, 3) Resolution-aware images, 4) Font integration, 5) Asset variants handling, 6) Package asset access, 7) Asset loading optimization, 8) Asset organization strategies.
Stack and Positioned: 1) Stack allows overlapping children, 2) Positioned controls child position, 3) Stack alignment properties, 4) Positioned absolute positioning, 5) Stack fit behavior, 6) Z-index ordering, 7) Overflow handling, 8) Size constraints management.
Popular state management solutions include: 1) Provider for dependency injection and state management, 2) Bloc pattern for reactive state management, 3) GetX for simple state management, 4) Riverpod for improved Provider pattern, 5) MobX for reactive programming, 6) Redux for unidirectional data flow, 7) InheritedWidget for built-in state propagation, 8) State management with ValueNotifier.
Key differences: 1) Ephemeral state is local to a widget, 2) App state is shared across multiple widgets, 3) Ephemeral state uses setState(), 4) App state needs state management solution, 5) Ephemeral state for UI-only state, 6) App state for business logic, 7) Ephemeral state is simpler to manage, 8) App state requires careful architecture.
ChangeNotifier provides: 1) Simple state change notifications, 2) Listener management, 3) Mixin capabilities, 4) Integration with Provider, 5) Automatic cleanup, 6) Fine-grained updates, 7) Memory leak prevention, 8) Widget rebuild optimization.
