1 - Describe the architecture of a Flutter application.
Flutter uses a layered architecture with a Dart runtime, a UI framework (Flutter engine), and a platform specific layer that interacts with native code.
2) Explain the difference between a StatefulWidget and a StatelessWidget.
A StatefulWidget maintains internal state that can change over time, while a StatelessWidget is immutable and does not maintain state.
3) How does Flutter handle state management?
Flutter uses a declarative approach to state management through widgets. State is updated by rebuilding the widget tree based on changes in its properties.
4) What are some key performance optimization techniques in Flutter?
Using immutable state, avoiding unnecessary rebuilds, optimizing rendering, and minimizing memory usage.
5) How can you integrate native code into a Flutter application?
Through platform channels, which allow communication between the Dart and native code.
6) Explain the concept of reactive programming with Flutter's StreamBuilder.
StreamBuilder provides a way to build a UI that reacts to changes in a stream of data, allowing for dynamic updates.
7) How do you implement navigation in Flutter?
Using the Navigator widget to push and pop pages on a stack, and providing named routes for easy navigation.
8) What are some common debugging techniques in Flutter?
Using print statements, debugging tools like the Flutter Inspector, analyzing logs, and running unit tests.
9) Discuss the advantages of Flutter for building cross platform applications.
Fast development, native like performance, simplified UI development, and a large community and ecosystem.
10) How does Flutter handle accessibility and localization?
Flutter provides accessibility features through ARIA attributes, and internationalization support through i18n and l10n mechanisms.
11 - What are some best practices for designing Flutter applications?
Following Material Design guidelines, using semantic widgets, adhering to coding conventions, and implementing responsive layouts.
12) Describe the testing strategies for Flutter applications.
Unit testing with frameworks like Mockito, integration testing with Flutter Driver, and end to end testing with tools like Appium.
13) How do you deploy a Flutter application to production?
Using platforms like Firebase App Distribution or Expo, or through app stores like Google Play and the App Store.
14) What are the latest developments and trends in Flutter?
Support for the web, a new responsive layout system (Flex), and improvements in performance and tooling.
15) Discuss the challenges and limitations of using Flutter.
Potential performance limitations on low end devices, limited support for some native features, and a need for platform specific knowledge for some tasks.
There are a few ways to get more points on your credit report.
- Pay your bills on time, every time. This is the most important factor in your credit score. Payment history counts for 35% of your score.
- Keep your credit utilization low.* Credit utilization is the amount of credit you're using compared to the amount of credit you have available. Keeping your utilization below 30% is ideal.
- Don't open too many new credit accounts in a short period of time.* Each time you apply for new credit, it triggers a hard inquiry on your credit report. Hard inquiries can temporarily lower your score.
- Dispute any errors on your credit report.* If you find any errors on your credit report, you should dispute them with the credit bureaus. Errors can negatively impact your score.
- Become an authorized user on someone else's credit card.* If you have a friend or family member with good credit, you can ask them to add you as an authorized user on their credit card. This will help you build your credit history and improve your score.
- It takes time and effort to build a good credit score. But by following these tips, you can get more points and improve your creditworthiness.
