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

```dart
enum Season {
  fall, 
  winter,
  spring,
  summer,
}
```

```dart
Enum Season {
  fall, 
  winter,
  spring,
  summer,
}
```

```dart
enum Season {
  Fall, 
  Winter,
  Spring,
  Summer,
}
```

```dart
  const FALL = ‘Fall’;
  const WINTER = ‘Winter’;
  const SPRING = ’Spring’;
  const SUMMER = ‘Summer’;
```

Pick the correct enum definition for seasons of the year: Fall, Winter, Spring, and Summer.


Pick the correct enum definition for seasons of the year: Fall, Winter, Spring, and Summer.

Compilation error for missing case clauses for the rest of the seasons.

```text
Switch Seasons.
It’s Fall season.
```

What is the output of the code below?

**Enumeration:** 
```dart
enum Season {
  fall, 
  winter,
  spring,
  summer,
}
```
**Code:**
```dart
  var season = Season.Fall;
  print("Switch Seasons.");
  switch(season) {
    case Season.Fall:
      print("It’s Fall season.");
      break;
  }
```

What is the output of the code below?
Enumeration:
<pre><code class="language-dart">enum Season {
 fall, 
 winter,
 spring,
 summer,
}
</code></pre>
Code:
<pre><code class="language-dart"> var season = Season.Fall;
 print(&quot;Switch Seasons.&quot;);
 switch(season) {
 case Season.Fall:
 print(&quot;It’s Fall season.&quot;);
 break;
 }
</code></pre>
