Flutter is an open-source UI software development toolkit by Google for building natively compiled applications for mobile, web, and desktop from a single codebase.

Plugins and packages in Flutter are reusable libraries that help extend app functionalities like accessing device hardware or implementing specific features.

Flutter uses the Navigator and routes for screen transitions and managing app navigation.

FlutterFlow is a no-code/low-code platform that helps build Flutter apps visually, reducing development time.

MaterialApp: Adheres to Material Design guidelines (used for Android).

The widget tree represents the hierarchical structure of UI components in a Flutter app, influencing layout and behavior.

Install the Flutter plugin in Android Studio, then configure the Flutter SDK path to start building Flutter apps.

Key advantages of Flutter include fast development, cross-platform compatibility, rich UI, and high performance.

StatelessWidget: Immutable and does not change its state.

Widgets are the building blocks of a Flutter app, used to define UI elements and behaviors. They include stateless widgets and stateful widgets.

Add the Firebase plugin to your Flutter project, configure the google-services.json or GoogleService-Info.plist files, and use Firebase SDKs.

Yes, Flutter supports web development, enabling apps to run seamlessly on browsers using the same codebase.

Deployment involves building the app using flutter build commands and publishing it on platforms like Google Play Store, App Store, or the web.

Null safety in Dart ensures variables cannot hold null values unless explicitly declared nullable, reducing runtime errors.

Flutter offers better performance due to its native rendering engine, while React Native relies on a JavaScript bridge.

Dart is the programming language used in Flutter. It is optimized for building UI and supports features like async programming and AOT (Ahead-of-Time) compilation.

Responsive layouts in Flutter adjust UI components dynamically based on screen size, using widgets like MediaQuery and LayoutBuilder.

The pubspec.yaml file in Flutter manages app dependencies, assets, and metadata.

State management in Flutter can be done using solutions like Provider, Bloc, Riverpod, or GetX.

Flutter provides animation widgets like AnimatedContainer, TweenAnimationBuilder, and Hero animations for smooth transitions and effects.

The Flutter inspector helps debug UI layouts and understand widget structures during app development.

Hot reload allows developers to see changes instantly in the app without restarting, enhancing productivity in Flutter development.

Use the Flutter DevTools, Android Studio debugger, or VS Code Debugger to debug Flutter applications effectively.

Popular IDEs include Android Studio, VS Code, and IntelliJ IDEA, all supporting Flutter development with plugins.

Flutter provides a single codebase, hot reload, and access to a rich set of customizable widgets, making it a preferred choice for cross-platform app development.
