1 - What is Flutter?
Flutter is an open source UI framework developed by Google for creating natively compiled applications for mobile, web, desktop, and embedded devices from a single codebase.
2) Why use Flutter?
Flutter offers cross platform development, fast development with Hot Reload, customizable widgets, and access to native features.
3) What's special about Flutter's architecture?
Flutter uses a layered architecture with a Dart VM and Skia graphics engine, providing fast performance and portability across platforms.
4) What are the benefits of using Dart with Flutter?
Dart is a fast, safe, and expressive language optimized for Flutter. It supports Ahead of Time (AOT) compilation and Native Ahead of Time (NAOT) compilation for efficient app execution.
5) How does Flutter handle state management?
Flutter uses a reactive programming model with widgets that track their state. The BLoC (Business Logic Component) and Redux patterns are popular for more complex state management.
6) What are the advantages of using Hot Reload?
Hot Reload allows developers to instantly see changes made to their code in the running app without having to restart it, greatly speeding up the development process.
7) What are some of the popular Flutter widgets?
Flutter provides a rich set of widgets including buttons, menus, sliders, forms, and layout widgets, allowing for easy and customizable UI creation.
8) How can I access native platform features in Flutter?
Flutter supports platform channels that enable communication between the Dart code and native code, providing access to platform specific features and APIs.
9) What is the Flutter SDK?
The Flutter SDK includes tools like the Flutter CLI, Dart SDK, Flutter editor plugins, and documentation for development and deployment.
10) How to deploy a Flutter app?
Flutter apps can be deployed to devices or emulators, packaged into APKs or AABs for Android, IPAs for iOS, or standalone executables for web and desktop.
11 - What resources are available for Flutter learning?
There are extensive official documentation, codelabs, tutorials, and community support available for learning and developing with Flutter.
12) Is Flutter suitable for enterprise development?
Yes, Flutter is used by many enterprises for cross platform app development due to its high performance, security features, and support for enterprise deployment tools.
13) What is the future of Flutter?
Flutter continues to evolve with new features, performance improvements, and wider platform support. Google's ongoing investment in Flutter ensures its long term viability.
14) What are some real world examples of Flutter apps?
Popular apps built with Flutter include Google Pay, Stadia, Hamilton, and BMW Connected.
15) Is Flutter suitable for game development?
Flutter can be used for 2D game development, but it's not optimized for 3D games. Consider using dedicated game engines for complex 3D games.
