Dart is a fully object-oriented, class-based, simple, and clean language. Google’s popular mobile framework, Flutter uses Dart language to implement high-quality native applications, so it’s recommended that you understand Flutter before beginning this course.

In this course, you will dive deep into Dart 2 language features while using interactive hands-on code playgrounds. This course will help you become confident with Dart extensions, enums, mixins, generics, libraries, asynchronous programming, class variables, callable classes, and generator functions.

By the end of this course, you will have a strong understanding of Dart principles, and you’ll be ready to start using this powerful language in your own projects.

Developing Web Applications with Dart

# Problem Statement
Assume you have an app that fetches data from a remote server. Depending on the type of response received from the server, the app could have one of the following states:
* **done**: The app received the response successfully.
* **waiting**: The app is waiting for the response.
* **error**: The app received an error from the server.

**Challenge #1:** Declare the enumeration `Status` to represent the above three cases.

**Challenge #2:** Print the following message for each status using the `switch` block.
* `Status.done`: The data is ready!
* `Status.waiting`: The app is waiting on a response from the server.
* `Status.error`: An error occurred.

**Challenge #3:** Add one more status: `delayed` to `Status.` Add the code to handle the default case.

Test your skills in implementing enumerated types in this challenge.
