- Mobile
What is Flutter and what are its key advantages?
Flutter is a UI toolkit for building natively compiled applications across mobile, web, and desktop from a single codebase.
Explain the widget system in Flutter.
Everything in Flutter is a widget, including layout, styling, and gestures, making UI highly customizable.
How does Flutter handle state management?
State management can be done via setState, Provider, Bloc, Redux, or other patterns to manage UI state reactively.
What is the difference between StatefulWidget and StatelessWidget?
StatelessWidget has immutable state, while StatefulWidget can change state dynamically during runtime.
Describe how Flutter achieves high performance.
Flutter compiles to native ARM code and uses its own rendering engine for fast UI performance.
How do you handle navigation in Flutter apps?
Navigation can be handled via Navigator class, routes, and libraries like go_router for declarative routing.
What is the role of the pubspec.yaml file?
pubspec.yaml manages project dependencies, assets, and metadata for Flutter projects.
Explain how to debug and profile Flutter applications.
Flutter provides DevTools for debugging, performance profiling, and inspecting widget trees.
What are some common challenges faced in Flutter development?
Challenges include platform-specific integrations, managing app size, and learning Dart language.
How does Flutter support web and desktop applications?
Flutter uses the same codebase and rendering engine to compile apps for web browsers and desktop platforms.
