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.

What are the ways to represent parameter names for generics? Select all that apply.

What are the ways to represent parameter names for generics? Select all that apply.

**E**: The letter E is used to represent the element type in a collection like List.

**R**: The letter R is used to represent the return type of a method or function.

**V**: The letter V is used to represent the value type in associative collections like Map.

**K**: The letter K is used to represent the key type in associative collections like Map.

What is the output of the code below:
```dart
void main() {
 List<List<String>> theList = List<List<String>>.from([
 ['Hi']
 ]);

 theList.add(['hello']);

 for (List item in theList) {
 print(item);
 }
}

```

What is the output of the code below:
<pre><code class="language-dart">void main() {

 ['Hi']
 ]);

 theList.add(['hello']);

 for (List item in theList) {
