1 - Explain the bloc pattern: It's a state management pattern that follows the principles of unidirectional data flow and immutability.
2) Describe the provider package: It's a dependency injection framework for Flutter that allows you to share objects and state between different parts of your app.
3) Explain the difference between a bloc and a provider: Blocs manage state, while providers manage dependencies.
4) When should you use a bloc over a provider?: Use a bloc when you need to manage complex state that requires business logic.
5) Describe the layered architecture for Flutter apps: Typically includes a presentation layer for UI, a domain layer for business logic, and a data layer for data access.
6) Explain the importance of testing in Flutter: Testing ensures that your app works as expected and reduces the risk of bugs in production.
7) Describe the different types of tests you can write in Flutter: Unit tests, widget tests, and integration tests.
8) Explain the purpose of the Flutter DevTools: It's a set of tools that help you debug, analyze, and test your Flutter apps.
9) Describe the hot reload feature in Flutter: It allows you to make changes to your code and see them reflected in your running app without restarting it.
10) Explain the difference between a stateful and a stateless widget: Stateful widgets can change their state over time, while stateless widgets cannot.
11 - Describe the build method in a Flutter widget: It's where you define the UI for your widget based on its current state and the context it's in.
12) Explain how to handle user input in Flutter: Use event handlers such as onTap, onPressed, and onChange.
13) Describe the navigation system in Flutter: It allows you to navigate between different screens and manage the app's back stack.
14) Explain how to use the FutureBuilder widget: It's used to load data from an asynchronous source and display a loading indicator while the data is loading.
15) Describe the StreamBuilder widget: It's used to listen to a stream of data and update the UI accordingly.
16) Explain how to use the ChangeNotifier class: It's used to notify listeners when the state of an object changes.
17) Describe the Provider package: It's used for dependency injection and state management in Flutter applications.
18) Explain how to handle errors in Flutter: Use the try catch block or the FlutterError widget.
19) Describe the importance of performance optimization in Flutter: To ensure your app runs smoothly and efficiently.
20) Explain the different techniques for performance optimization in Flutter: Caching, lazy loading, using the correct widgets, and avoiding unnecessary rebuilds.
